Perancangan Ulang Tata Letak Fasilitas Internal Warehouse Untuk Meminimasi Ongkos Material Handling

Warehouse of Company X has two production supply destinations, TFD 315 and TFD 500. One of the supply destinations has a high workload for the forklift driver. It happened because of the long distance when doing material handling. Warehouse’s layout of company X is not optimal that causing huge material handling costs. So, relayout of the facilities is done in order to reduce material handling costs by shortening the distance between facilities based on the relationship of material handling activities. The stages of this research are data collection, calculating distance and material handling costs for the initial facility layout, making the activity relationship chart (ARC) between facilities, planning the new facility layout, then calculating the distance and cost of material handling of the new layout, and the last is comparing the initial and the new material handling costs. The results of this research is that after doing relayout of warehouse facility layout, material handling costs are reduced by 21.07% from the initial cost.

Universal Turning Forklift

Abstract: We describe the development of robotic forklift intended to operate alongside human personnel, handling palletized materials within existing, busy, semi-structured storage facilities. The main objective of this project is to fabricate a Mechanical forklift for material handling in industries. In this project a Universal Turning Forklift is fabricated which runs to carry material from one place to another by using Android App. To use forklift, it requires one spot guide to guide a forklift driver because of less visibility. This project discusses how to integrate Android App based remote controlled technology into a forklift to make it wireless to increase visibility and human safety. Along with this the forklift designed in this project can move in a semi-circular path from left to right hence it becomes more easier for the user to setup the warehouse efficiently.

Enlarging verrucous plaque in a Guatemalan male

A 43-year-old man is being evaluated for intractable pain from an enlarging plaque of 10 years' duration on his left knee. He emigrated from Guatemala 6 months ago and previously worked as a farmer and forklift driver. Originally focal, the lesion progressed to encompass the entire knee, medial leg, and distal thigh. Prior treatment with topical triamcinolone provided no benefit in reducing lesion size or symptoms. Physical examination demonstrates a 30 × 40–cm, indurated, verrucous plaque with central scarring, scalloped borders, and overlying white adherent scale (Fig 1).

Assessing occupational risk factors for forklift drivers

L’utilisation d’équipements de manutention est incontournable dans une chaîne d’approvisionnement en supply chain pour déplacer divers types de produits. Les chariots élévateurs à fourche figurent parmi les équipements les plus connus et les plus utilisés dans presque tous les secteurs, en particulier dans les entrepôts et les services d’expédition. Il est courant de considérer que le fait de transporter le bon matériel selon la bonne quantité en toute sécurité et en temps utile est lié à l’expérience du conducteur de chariot élévateur. S’il est prouvé que la conception des chariots élévateurs à fourche peut affecter les performances d’un conducteur, l’influence des facteurs environnementaux et cognitifs n’est en revanche pas étudiée en détail. Cette étude vise à examiner ces facteurs de façon à améliorer la santé et la sécurité au travail des conducteurs de chariots élévateurs. Une enquête a été conçue pour recueillir des informations sur les conducteurs de chariots élévateurs, leur niveau de confort vis-à-vis des facteurs environnementaux et leurs commentaires sur la conception et l’utilisabilité des chariots élévateurs. Les facteurs environnementaux sont mesurés à l’aide d’un multi-mètre. Le questionnaire de Cornell sur l’inconfort de l’appareil locomoteur (Cornell Musculoskeletal Discomfort Questionnaire) a été appliqué. Un eye-tracker portable a été utilisé pour collecter et analyser les données relatives à la durée et au nombre de fixations du regard, ainsi qu’à la modification de la taille de la pupille en tant qu’indicateur de la charge cognitive pour les tâches de manipulation de palettes. Les résultats sont analysés au moyen d’un test ANOVA. Ils conduisent à attirer l’attention sur l’importance de prendre en compte la situation de travail dans sa globalité et de demander l’avis des conducteurs sur le terrain.

Development of automated monitoring safety system of the forklift DP 3510

In this article, the problem of ensuring the safe operation of the forklift truck is analyzed, as well as the development of an automated monitoring system for preventing the occurrence of accidents in the territory of warehouses, enterprises and organizations using special transportation equipment. A model of the DLE system has been developed: Truck loader driver (D), Auto-loader (L), Environment (E). Hazard sources during loading operations are identified. Based on the analysis of the necessary and sufficient conditions for the transition of system states, an instrumental security assessment model has been developed that is used in the synthesis of a finite state machine. A ladder circuit and a forklift driver’s console have been developed, implemented on the Omron software and hardware system. The developed onboard computer for the forklift truck takes into account the load of the mechanisms when lifting the load and, if it is necessary, generates an alarm or blocking mechanisms in a dangerous situation.

The Effect of Forklift Driver Behavior on Energy Consumption and Productivity

This research investigates the impact of forklift driver behavior on energy consumption and productivity (i.e., the average number of pallet movements per operating hour) by conducting various statistical and regression analyses. Forklift driver behavior data are collected from actual warehouse setting to evaluate the relationships between different driving behaviors (i.e., concurrent travel and lift, travel speed, acceleration, and braking) and driver performance. The research results show that 1) drivers perform similar tasks have different driving behaviors; 2) driver productivity increases with longer durations of concurrent travel and lift; and 3) average speed is the most significant variable that affects the energy consumption.

Two Cases of Lung Cancer in Foundry Workers

BackgroundIron and steel foundry workers are exposed to various toxic and carcinogenic substances including crystalline silica, polycyclic aromatic hydrocarbons, and arsenic. Studies have been conducted on lung cancer in iron and steel founding workers and the concentration of crystalline silica in foundries; however, the concentration of crystalline silica and cases of lung cancer in a single foundry has never been reported in Korea. Therefore, the authors report two cases of lung cancer and concentration of crystalline silica by the X-ray diffraction method.Case presentationA 55-year-old blasting and grinding worker who worked in a foundry for 33 years was diagnosed with lung cancer. Another 64-year-old forklift driver who worked in foundries for 39 years was also diagnosed with lung cancer. Shot blast operatives were exposed to the highest level of respirable quartz (0.412 mg/m3), and a forklift driver was exposed to 0.223 mg/m3.ConclusionsThe lung cancer of the two workers is very likely due to occupationally related exposure given their occupational history, the level of exposure to crystalline silica, and epidemiologic evidence. Further studies on the concentration of crystalline silica in foundries and techniques to reduce the crystalline silica concentration are required.

Vibration Research on Fork-Lift Truck by Harmonic Analysis

Aimed at the vibrations of driver seat and wheel of a working fork-lift truck, the acceleration was measured and a vibration analysis based on the finite element method was made. Comparing the finite element analysis result with the result of model test analysis, the finite model is modified with the result of test. The mode analysis is done. The result shows that the fork-lift truck driver seat and wheel frequency is far away from the exciting frequency of engine. The vibration is forced vibration but not resonance.

Real‐time performance monitoring, goal‐setting, and feedback for forklift drivers in a distribution centre

In this study conducted in two auto‐parts after‐market distribution centres, immediate performance goals and feedback were delivered to employees in a warehouse on wireless vehicle‐mounted computers. Engineered labour standards (ELS) calculated work‐unit goal times and presented the driver with immediate performance feedback. Ultimately, the ELS feedback was linked to the company's forklift driver team pallet‐per‐hour quota achievement. Replenishment performance for forklift drivers (N=12) was improved by 2.14 pallets per hour when an intervention package that included the depiction of goal times and immediate performance feedback on wireless vehicle‐mounted computers and a newly developed ELS. The implications of these findings, limitations, and safety issues are discussed in terms of operational issues regarding ELS in large industrial settings.

Case study: Aluminum‐dust explosion

AbstractAn explosion occurred in equipment that was being used to pulverize aluminum‐alloy ingots, to form a powder with small particle size. In this process, air was recycled through a grinder, cyclone product separator, and blower, with a side stream to extract undesired dust to a dust collector. However, the concentration of dust in the circulating air stream was above the minimum explosible concentration in most of the recycle system. Ignition of this dust/air dispersion occurred as a result of an exothermic oxidation of accumulated combustible dust in the return‐air ductwork, accelerated by the relatively high temperature of the circulating air. Because the system was not protected against internal explosion, an access door on the grinder was forcibly ejected, and the door struck a hose on the liquefied petroleum gas (LPG) cylinder on a nearby forklift truck. Escaping LPG vapors—ignited by the dust fireball from the open grinder door—resulted in a flash fire that caused fatal burn injuries to the forklift driver. The primary cause of this incident was failure to adequately manage changes to the process. The causes and lessons learned as a result of this incident are described in detail, together with recommendations for improved practices to avoid similar events. Although they are related to this specific incident, the lessons are especially relevant for preventing combustible‐dust explosions. © 2007 American Institute of Chemical Engineers Process Saf Prog 2008

THE FATE OF MRS ROBINSON: CRITERIA FOR RECOGNITION OF WHOLE-BODY VIBRATION INJURY AS AN OCCUPATIONAL DISEASE

Several recently published critical reviews conclude that there is strong epidemiological evidence for a relationship between occupational exposure to whole-body vibration (WBV), low back pain (LBP) and back disorders. Whether this exposure is only a modest or a substantial risk factor for the onset and recurrence of LBP is still a matter of debate. In spite of this controversy, four European Union countries have decided to recognize and compensate LBP and certain spinal disorders as an occupational disease. In this paper, we review the criteria currently in use for the recognition of this occupational disease. A search of the literature was performed; additional information was obtained in work visits to national occupational disease institutes in Germany, France and Belgium, in annual reports and national statistics on occupational diseases. Belgium was the first country to add WBV injury to the official list of occupational diseases (1978), followed by Germany (1993), the Netherlands (1997), and France (1999). The incidence of newly recognized cases in 1999 varied considerably: 763 in Belgium, 269 in France, 16 in Germany, and 10 reported cases in the Netherlands. The findings of this review indicate that significant differences exist in the established and applied diagnostic and exposure criteria in the four EU countries. This is illustrated by the case of Mrs Robinson, a 41-year-old forklift driver with LBP, who would probably get recognition and compensation in the Netherlands and Belgium but would be rejected in France and Germany. The development of uniform internationally accepted criteria is recommended, also from an epidemiological point of view, as many data are collected in the process of recognition of this occupational disease.

Evaluation of a swiveling seat to reduce the physical load on forklift drivers

Many forklift drivers have musculoskeletal disorders such as low back pain related to poor work posture and whole-body vibration. With a forklift operator's seat capable of 45-degree swiveling, we evaluated the physical reduction in the load in 10 subjects working in a back-looking position by means of surface electromyography (EMG) and the angle of rotation of the trunk and neck regions. The amplitude of surface EMG on the trapezius, erector spinae, and latissimus dorsi muscles in looking back or maintaining a back-looking position decreased with a swiveling seat compared to the stationary seat. Nevertheless, there was little alleviation of the amplitude of surface EMG on the sternocleidomastoid muscle in maintaining a back-looking posture and no decrease in looking back. The angle of rotation of the trunk maintaining a back-looking position was decreased greatly with the swiveling seat, but no decrease in the rotation angle of the neck was seen. Our study suggests that a swiveling seat is effective in reducing the physical load on the forklift driver during back-looking operations, and this may lead to the prevention of low back pain.

Effect of fork-lift truck driving on low-back trouble.

In a population of 240 male fork-lift truck drivers who drove at least 4 h daily, the occurrence of low-back trouble was studied in relation to that of two reference groups. The participation rate of the fork-lift truck drivers was 88%. The responses to a questionnaire concerning low-back trouble were reviewed. Among the fork-lift truck drivers, a statistically significant higher occurrence of low-back trouble was reported for the year preceding the study, in comparison, according to age, to that of a reference group of 399 working men (65 against 47%); however, there was no significantly increased frequency when compared to that of a reference group of 66 unskilled male workers (65 against 51%). The fork-lift truck drivers had a significantly higher rate of absence from work within the previous year due to low-back trouble than the two reference groups (22% compared to 7 and 9%). These findings were confirmed during the follow-up year. A correlation was found between length of employment as a fork-lift truck driver and the occurrence of low-back trouble within the preceding year. It was concluded that fork-lift truck driving may be a contributory cause for low-back trouble.
