Abstract:

The increase of the number of forklifts is associated with the elevated threat of accidents and dangerous situations that should be systematically analyzed. On the occasion of the assessment, it is worth using accident ratios for given devices and dangerous situations. The article presents the results of research into the causes and effects of accidents at work of forklift trucks’ operators in 2011÷2017. The most serious accident occurred in the case of: loss of stability of the forklift truck at the bend, crush caused by the truck, impact by the truck’s load, impact by the truck itself. Most injuries arose in the case of: overturning when reversing the truck, overrunning employees’ leg, crush by the truck or its load, impact by the truck. The safety of work of the forklift trucks operators under full supervision has improved. Errors in the operation of trucks increased, which requires more frequent verification of operators' skills and the increase of their awareness of hazards.

Abstract:

Purpose Forklift trucks are generally operated with frequent accelerations and stops, reverse and operations of load handling. This way of operation increases the energy losses and consequently the need for reduction of fuel consumption from forklift customers. This study aims to build a model to replicate the performance of forklifts during real operations and estimate fuel consumption without building a real prototype. Design/methodology/approach AVL Cruise has been used to simulate forklift powertrain and hydraulic circuit. The driving cycles used for this study were in accordance with the standard VDI 2198. Artificial neural networks (ANNs), trained by the results of AVL Cruise simulations, have been used to forecast the fuel consumption for a large set of possible driving cycles. Findings The comparison between simulated and experimental data verified that AVL Cruise model was able to simulate the performance of real forklifts, but the results were only valid for the specified driving cycle. The ANNs, trained by the results of AVL Cruise for a certain number of driving cycles, have been found effective to forecast the fuel consumption of a larger number of driving cycles following the prescriptions of the standard VDI 2198. Originality/value A new method based on ANN, trained by AVL Cruise simulation results, has been introduced to forecast the forklift fuel consumption, reducing the computational time and the cost of experimental tests.

Abstract:

This article describes that ergonomic design, improved operation, and increased lifting capability are key elements in the latest models of hydraulic forklifts. More supportive seats and touch-sensitive hydraulic controls are among the ergonomic innovations that Mitsubishi engineered into its latest generation of forklifts. Mitsubishi forklift engines are equipped with hardened steel valve inserts and automatic valves to extend their reliability throughout the length of their performance life. The Mitsubishi designers worked on improving the operator's ability to see through the forklift truck's mast, the structure that carries the forks, by repositioning the hydraulic cylinders and the multiplying chain. Outdoor forklift trucks, also known as rough terrain lift trucks, have been undergoing a change as well. These vehicles offload pallets of bricks, concrete blocks, insulation, and lumber delivered to construction sites. An operator mounts the Manitransit forklift on the rear of a trailer by inserting its forks into the truck's sleeves so that it can be transported to and from unloading sites. The forklifts give drivers full visibility because the telescopic boom needs no mast that might obstruct the view over the forks and load. The boom is mounted low on the truck to ensure a clear field of vision.

Abstract:

This study investigates the dynamic behavior of a recently developed counterbalance forklift truck. The final objective is creating virtual testing tools based on numerical multibody models to evaluate the dynamic stresses experienced by the forklift family of interest during a reference operating cycle, defined by the manufacturer’s testing protocols. This work aims at defining sufficiently accurate and easy-to-implement modelling approaches and validation procedures. It focuses on a specific test, namely the passage of a speed-bump-like obstacle at high velocity, which represents one of the most severe conditions within the reference cycle. Indeed, unlike most of the other wheeled vehicles, forklifts typically do not have advanced suspension systems and their dynamic response is significantly affected by ground irregularities. To this end, a preliminary model of the complete forklift, featuring rigid bodies and a simplified tire–ground contact model, is implemented with a commercial software. Experimental tests are conducted on the forklift to measure the vehicle vibrations when running on the obstacle, for model validation purposes. After model updating, the results provided by the numerical simulations match the experimental data satisfactorily. Hence, the modelling and validation strategies are proven viable and effective.

Abstract:

Today’s demand on forklift trucks performance and efficiency is high. The productivity is important but also the experience while handling the forklift. The handling has to be simple and genuine to make the driver feel confident and safe. To achieve high performance steering in articulated trucks, a hydraulic power system is often used.Simulation software are a powerful tool in development processes. The program gives the industry a possibility to develop, analyze and evaluate constructions and models more efficient.The purpose of this master thesis is to identify and increase the knowledge about the main challenges in the hydraulic steering system in an articulated forklift. The hydraulic system has been modelled in the simulation software Hopsan and validated against data from measurements performed on the forklift. The different challenges have been identified based on tests and the simulation results. For a deeper understanding of the system a literature study, mainly about the key components, has been done during the master thesis. A number of suggestions for improvement have been developed with focus on increasing the steering performance. The concepts and ideas have been evaluated and tested in the simulation model.The project resulted in a validated simulation model of the articulation and a number of suggested improvements on the hydraulic steering system.

Abstract:

The prevention of incidents and injuries is fundamental for any industry activity since those events may result in serious economic, environmental, and human losses. Due to the centralization of Linde filling operations within Sweden, several of their plants are being phased out to move the production to Enköping. The elevated raise of Linde's production led to a high increase of forklift drivers and stock levels and consequently brought up the number of incidents related to forklift driving. This thesis aims to obtain knowledge to mitigate forklift truck related safety hazards as well as understand how to eliminate risks and unsafe situations at this type of operation. This project was divided into 3 phases. Phase I consisted of understanding operations routines and its safety risks, assessing Enköping site internal state (with a safety survey, and several visits and interviews), and benchmarking the most common practices based on other companies' forklift-related processes (with visits and interviews). In phase II, parallelly to ISite software implementation, studies utilizing different engineering tools (Spaghetti Diagram, VSM, Fishbone Diagram, and FMEA) were performed in order to gather information and understand how to optimize the site's forklift-related safety. In this phase, a tailored observational KPI was developed in order to assess the site independently of incident measurement regarding four groups: Site, Pedestrian activity, Forklift operation, and Forklift operator behavior. In phase III, all data acquired was discussed, and conclusions were made based on the data analysis and discussions of the results of Phase II implementation allied with the theoretical references. The survey findings showed the high degree of importance given to safety at Linde in Enköping. It also revealed, in addition to all engineering tools applied, which elements should be focused in order to optimize the forklift trucks operational safety (mainly related to Technology dimension). Based on the benchmark comparison, it is possible to allege that the absence of a maintenance facility is the main disadvantage of Linde in Enköping. In contrast, the usage of I-Site fleet management software represents an important step towards safety. The I-Site knowledge and the awareness of its benefits grew among management and operators as setup issues, and technical malfunctioning was eliminated. The observational KPI has obtained preliminary overall values above 0,82 for all groups (on a scale of 0 to 1), proving itself capable of measuring the safety performance and identifying risks and unsafe situations.
Att förebygga incidenter och skador är grundläggande för all branschaktivitet eftersom dessa händelser kan leda till allvarliga ekonomiska, miljömässiga och mänskliga förluster. På grund av centraliseringen av Lindes fyllningsverksamheten inom Sverige har flera av deras anläggningar fasats ut för att flytta produktionen till Enköping. Den utökade produktionen på Linde Enköping skapade behov av fler truckförare, högre lagernivåer och ökade följaktligen antalet incidenter relaterade till gaffeltruck. Avhandlingen syftar till att få kunskap för att mildra säkerhetsrisker för gaffeltruckar samt förstå hur man kan eliminera risker och osäkra situationer vid denna typ av verksamhet. Detta projekt delades in i tre faser. Fas I bestod av att förstå driftsrutiner och dess säkerhetsrisker, utvärdera det interna tillståndet på Linde Enköpings arbetsplats (med en säkerhetsundersökning, flera besök och olika intervjuer) och benchmarka de vanligaste metoderna baserat på andra företags gaffeltruckrelaterade processer (med besök och intervjuer). I fas II, parallellt med I-Site-programvaruimplementering, utfördes studier med olika tekniska verktyg (Spaghetti Diagram, VSM, Fishbone Diagram och FMEA) för att undersöka och förstå hur man optimerar verksamhetens gaffeltruckrelaterade säkerhet. I denna fas utvecklades en skräddarsydd observations-KPI för att utvärdera verksamheten oberoende av att mäta incidenter avseende fyra grupper: Plats, fotgängare, gaffeltruck och beteende för gaffeltruck. I fas III diskuterades alla förvärvade data, slutsatser gjordes baserade på dataanalysen och diskussionerna om resultaten av fas II-implementering tillsammans med teoretiska referenser. Undersökningsresultaten visade hur högt säkerhet prioriteras vid Linde Enköping. Den avslöjade också, utöver alla tillämpade konstruktionsverktyg, vilka element som bör fokuseras på för att optimera truckens driftssäkerhet (främst relaterad till teknikdimension). Baserat på den benchmarking som genomfördes är det möjligt att hävda att frånvaron av underhållsanläggning är den största nackdelen med Linde i Enköping. Däremot är användningen av mjukvara för I-Site-flottanhantering ett viktigt steg mot säkerheten. Kunskapen om I-SITE och medvetenheten om dess fördelar växte bland ledningen och operatörerna när installationsproblem och tekniska funktionsfel eliminerades. Utfallen för observations-KPI har erhållit preliminära totalvärden över 0,82 för alla grupper (i en skala från 0 till 1), och visar sig kapabel att mäta säkerhet i genomförande samt att identifiera risker och osäkra situationer.

Abstract:

Fuel economy has become an important consideration in forklift truck design, particularly in Europe. A simulation of the fuel consumption and performance of a forklift truck has been developed, validated and subsequently used to determine the energy consumed by individual powertrain components during drive cycles. The forklift truck used in this study has a rated lifting capacity of 2500kg, and is powered by a 2.6 litre naturally aspirated diesel engine with a fuel pump containing a mechanical variable-speed governor. The drivetrain consisted of a torque convertor, hydraulic clutch and single speed transmission. AVL Cruise software was used to simulate the vehicle powertrain, with coupled Mathworks Simulink models used to simulate the hydraulic and control systems, and fuel pump governor. The vehicle has been simulated on several performance and fuel consumption drive cycles with the main focus being the VDI 2198 fuel consumption drive cycle. To validate the model, a truck was instrumented and measurements taken to compare the performance and instantaneous fuel consumption to simulated values. The fuel injector pump was modified and calibrated to enable instantaneous fuel flow to be measured. The model has been validated to within acceptable limits and demonstrates how the model can be used to compare the fuel consumption and performance trade-offs when selecting drivetrain components.

Abstract:

This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip. The forklift truck was modelled using Simulink and validated by experiment. Different possible control strategies were investigated and three were chosen for implementation in simulation. These were controllers based on Model Following Control, Maximum Transmissible Torque Estimation and Sliding Mode Control. Model Following Control makes use of a nominal model to compare actual wheel speed values with nominal wheel speed values to determine if slip is occurring, Maximum Transmissible Torque Estimation makes use of a closed-loop disturbance observer to compute the maximum transmissible torque possible without inducing slip and using it as a limitation on the input signal, and Sliding Mode Control uses different functions to \say{slide} along a sliding surface to stay around a specific slip value. All three controller types were developed both as speed controlled and torque controlled. All of the controllers could reduce slip heavily in simulation. The Maximum Transmissible Torque Estimation controller reduced slip the most and kept oscillations at a minimum, but was not as responsive as the others to driver commands. The conclusion was that the controller of choice would depend on the working environment of the forklift truck. In a low friction environment where slip is expected to occur often, the Maximum Transmissible Torque Estimation controller is advisable, while the other two would be a better choice for environment with low slip occurrence. The use of torque control, while often better with regards to decreasing slip, could not be advised due to a perceived increase in implementation cost.

Abstract:

Reach truck masts are subjected to oscillations, which have signiﬁcant impacts on the dynamics of the entire vehicle. Mast oscillations can cause undesirable outcomes in extreme situations and therefore it is desirable to be able to predict these outcomes before they occur. A forklift manufacturer in Mjölby initiated a thesis with the intention to obtain a model that can simulate mast sway for situations where oscillations occur. The objective of the thesis was to create a model of Triplex masts and ﬁnd dependencies between model parameters and variables such as fork height and load. The thesis was conducted modelling the mast with a rigid multibody approach where torsion springs and dampers were used between mast parts to simulate mast elasticity. Clearance at the connections were considered and included in the model. The obtained model constitutes of 8 parameters that could be tuned to attain diﬀerent oscillation characteristics. Parametric optimisation was carried out to ﬁnd optimal sets of parameters for compliance with sway measurement tests with diﬀerent load and fork height cases. The thesis has resulted in a model that is able to simulate mast sway with diﬀerent oscillation characteristics depending on model parameters. Performed parametric optimisation resulted in parameters that reveal useful information about how model parameters depend on load and fork height. The method used for obtaining optimal parameters can likewise be applied to other mast models in order to gain insight into model parameters as functions of load and fork height.

Abstract:

The purpose of this thesis is to describe the steps undertaken in a “proof-of-concept” project aimed at improving the fuel efficiency of forklift trucks. In this study, a prototype forklift truck was developed which employs a continuously variable hydrostatic transmission in place of the traditional torque converter drivetrain. Through the application of backward- and forward-facing simulation techniques, a novel vehicle control system was created to target maximum drivetrain efficiency, while still working within the constraints of the prototype hardware and the demands of the driver. Different control strategies were designed to optimise the efficiency of the drivetrain in both steady-state and transient conditions, while several performance mode settings were included to allow the driver to adjust the trade-off between fuel consumption and maximum productivity. The prototype truck was tested in accordance with both VDI 2198 and VDI Turnover tests. When the quantity of work was fixed (i.e. during the VDI 2198 test), the control system and its various strategies proved to be functioning as desired by minimising the amount of fuel consumed to complete the task, regardless of the selected performance mode. When the quantity of work was not fixed (i.e. during the VDI Turnover test), a clear trend was demonstrated between fuel consumption and productivity depending on the selected performance mode, again proving that the control system was functioning as desired When compared to the current production truck of the same rated capacity, the prototype truck consumed an average of 36% less fuel over the VDI 2198 cycle. Additionally, the prototype vehicle also showed a 35% increase in effectivity (i.e. the number of loads moved per kilogram of fuel consumed) during the VDI Turnover test Finally, a forward-facing model of the prototype truck was created and partially validated using an industry-standard automotive simulation package with a view to allowing for future developments to be made through detailed vehicle simulation.

Abstract:

ABSTRACT Carton Clamp Test Methodologies and the Effects on Load Containment and Retention Tyler Don Blumer A carton clamp is an alternative device for moving packages and material. Instead of using iron tines like that of a conventional forklift, a carton clamp uses two large aluminum platens to slightly compress and secure the load for handling. This is advantageous as it allows operators to move layers of a unitized load individually, and eliminates the need for a pallet when handling full unitized loads. When using a carton clamp attachment, it is often difficult for operators to accurately gauge the amount of force being applied to the load. The required clamping force changes depending on the size, shape, and weight of the load. This creates the potential for under-clamping (slippage) and over-clamping (compressive damage). Seeing a market need for a reliable means of testing, two organizations set out to develop a testing protocol. A rift formed between schools of thought regarding the correct testing procedure. ISTA provides a sterile, calculated, and stationary simulation of carton clamp handling in its ISTA 6-SAMS test protocol. ASTM offers a more holistic, dynamic, observational approach in its mobile ASTM 6055 standard protocol. One school of thought is suggested to imply that a package should be developed to be handled by the carton clamp (ASTM). The other school of thought is that the carton clamp attachment should be properly adjusted to the package specimen (ISTA). Previous studies have been performed citing the ISTA standard and using a specialized carton clamping device vibration device that is calibrated for laboratory research. Arguably, this method, though repeatable in nature, does not accurately simulate carton clamp handling found in industry. Likewise, the equipment investment is cost prohibitive for those in industry wishing to duplicate such a study. ASTM uses a carton clamp truck as used in industry, but does not specify any specific parameters making repeatability between laboratories and practitioners ambiguous. This study examined whether or not a common ground can be reached; implementing a carton clamp lift truck as found in industry allowing for mobile (hazard course) testing. A modified version of ISTA 3B will be paired off against ASTM 6055 for evaluating both column and cross stack pallet patterns with a variety of treatments. This study attempted to determine if carton clamps as found in industry are capable and repeatable enough to provide consistent data. Similarly, this study examined the test methodologies effect on load containment via stretch film force, load retention via unitized load slippage, and the effects of ride height and driver interaction. The study sought to understand if these effects are uniform across the unitized load, or if particular layers of the load more affected than others.

Abstract:

Past studies have indicated that the greatest risk that a forklift operator faces is the hazard of an overturning forklift crushing the operator. This conclusion has been developed largely based on accident experience with sit-down forklifts. In contrast, this paper examines a data set of approximately 3,000 stand-up lift truck accidents (rather than sit-down forklifts) and finds that the operator of a stand-up lift truck is at greater risk of being involved in a collision with a stationary object than at risk for an accident involving the stability of the forklift. Greater than 50% of the approximately 3,000 accidents studied involved a collision between a stand-up forklift and a stationary object, resulting in approximately 700 serious injuries and 22 deaths of stand-up forklift operators. This paper will also identify the hazards associated with the use of stand-up lift trucks and the statistical likelihood of the hazard based on the approximately 3,000 accident data set.

Abstract:

This paper investigates the threshold of dynamic postural stability during standup forklift (lift truck) operation. Through a series of controlled tests, live subject data is gathered to determine the effect of upper extremity support during acceleration perturbation of the forklift (standing platform). The level of perturbation causing loss of balance is in close agreement with earlier studies and supports the use of a door in a standup forklift to arrest loss of balance, falling and injury during routine standup forklift (lift truck) operation.

Abstract:

This paper investigates dynamic standing postural stability during standup forklift operation through a series of live subject tests to determine the sensitivity to loss of stability and falling. Through a set of controlled tests, the tolerance to accelerations in the lateral, oblique, and longitudinal orientations is determined. The levels of acceleration causing loss of balance are in close agreement with earlier studies and support the use of a door in the case of a standup forklift and the use of a control corridor in the case of a pallet jack (walkie-rider) during routine operation.

Abstract:

This paper discusses the evaluation of the structural integrity of the SAFKEG radioactive material package to ensure hazardous material confinement during the postulated accident event of forklift truck collision. When a SAFKEG Package carried by a forklift truck traveling at 7 miles per hour collides with another forklift truck moving at the same speed but in the opposite direction, the structural response of the package components represents a complex problem. Because of its complex geometric configuration and complicated contact conditions between the neighboring component interfaces, the problem can not be solved using the implicit numerical scheme that would involve solving a large number of simultaneous equations through numerical iteration. In addition, material degradation and failure caused by collision can create severe convergence difficulties in the implicit analysis. Consequently, the explicit solution method is used in the present analysis, and thus the problem has to be treated as a dynamic one even though the inertia effect is insignificant due to the low speed of the forklift trucks. Applying the explicit dynamic technique to quasi-static problems involving very large deformation and material degradation require special considerations in overcoming solution convergence and extremely long computing time. The techniques used to overcome these difficulties are discussed in this paper. This paper also discusses the development of the constitutive models of the thermal insulating and shock absorbing materials used in the SAFKEG. The resin-bounded cork material is represented by the “crushable foam” plasticity with volumetric hardening. On the other hand, the material model of the brittle foam is developed by using the combination of the Mohr-Coulomb and Drucker-Prager plasticity theories. The analysis utilizes the finite-element method and the ABAQUS/Explicit Computer Code, version 6.3. A combination of the “General Contact” method and the “Contact Pair” method is employed to simulate the complicated interface variations among the neighboring components of the model.

In ASME 2016 International Mechanical Engineering Congress and Exposition. American Society of Mechanical Engineers, 2016. http://dx.doi.org/10.1115/imece2016-65169.

Full text

Abstract:

Neck and back loads of sit down forklift operators have not been fully evaluated in the scientific literature. In this study, we evaluate the neck and back loads of an obese forklift operator who experiences a sudden vertical drop while operating a sit down lift truck. A ballasted 50th percentile male anthropomorphic test device (ATD) was used to measure loads available to a sit down forklift operator. Telemetry was used to remotely operate the sit down lift truck with the ATD properly belted. The belted ATD and lift truck were traveling, forks-leading along a stationary flatbed trailer when the right front forklift tire dropped into a defect in the floor. Several runs were performed at forklift travel speeds less than 5 miles per hour (2.2 meters per second). Back loads of the ATD were compared to activities of daily living (ADLs); and neck and back loads of the ATD were compared to published human tolerance levels and Injury Assessment Reference Values (IARVs) used in compliance testing. Review of ADLs, IARVs, and tolerance data show little correlation between the potential for spinal injury and experiencing a sudden drop while operating a sit down lift truck.

Abstract:

A significant hazard related to the use of stand-up lift trucks, or stand-up forklifts, is the hazard of a lower limb crush injury or foot crush due to the opening across the rear of the operator compartment. According to one lift truck manufacturer’s statistics, there have been over 500 accidents that resulted in an injury to the lower limb of the operator in the last 30 years that involved their stand-up lift trucks. [1] Other manufacturers have had similar accidents. The injuries have occurred to the lower limb of the operator due to the close proximity of the operator’s lower limbs to the exterior of the lift truck, and the confined areas that stand-up lift trucks operate in. The operator’s lower limb can become pinned and crushed between the moving lift and another fixed object such as a rack system, a column or another lift truck. Objects, such as a fork tine, can also intrude into the operator compartment, injuring the operator’s lower extremities. The ANSI/ITSDF B56.1, Safety Standard for Low Lift and High Lift Trucks, encourages stand-up lift trucks to be designed with an open compartment to permit easy ingress and egress. [2] According to the standard, the open design allows an operator a free and easy egress from the truck in the event of a tip-over or off-the-dock accident. However, the standard permits the use of additional guarding and enclosure of the operator compartment. Spring loaded doors (or spring assisted closing guards) have been designed, implemented and are available from many manufacturers, but no data has been published regarding the time to open and egress from the operator compartment. Latching doors have also been designed and manufactured, but are not currently available on the market except in the case of trucks equipped with freezer cabs, for operation in refrigerated environments. However, latched doors have been criticized for extending the egress time duration by approximately 1/2 second. This study shows that a spring loaded door can be implemented on a stand-up forklift while only increasing egress time by a negligible amount, 0.05 seconds over an open compartment configuration. Furthermore, this study shows that an optimized latching door, designed by Knott Laboratory engineers, can also be implemented for a stand-up forklift while only increasing egress time by 0.09 seconds. The latching door designed by Knott Laboratory decreases the change in egress time associated with a latched door by a factor of 5. Therefore, the addition of a spring loaded door, or a latching door will not significantly increase operator egress time and provide additional protection to the operator in the event of a collision while still maintaining quick egress.

Abstract:

The objective of this study was to evaluate the properties and kinematics of an ASTM steel toe cage during quasi-static loading and forklift runover. Example ASTM F2413-05-compliant steel-toed shoes were loaded via forklift and via mechanical test device, and examined visually for external damage and fluoroscopically for internal displacement and damage of the steel-toed cage. Resulting displacement was quantified and analyzed to assess likely foot injuries and their location sustained by the wearer. When loaded by a lift truck, an ASTM F2413-05-compliant steel toe supported the weight without crushing, but the structure of the shoe around the steel cup did not, causing the steel toe to rotate and translate fore-aft or laterally, depending on the direction of loading. The survival of the steel toe combined with the failure of the shoe around it may lead to sparing of the toes, with crushing of the distal midfoot due either to direct or induced loading of the foot. Steel-toed shoes are unlikely to prevent injury to the midfoot or proximal phalanges when loaded by a forklift.
