Abstract

Manual loading of oil palm fresh fruit bunches (FFB) involves picking up the bunches with an iron spike and dropping them into a bin or tractor-trailer. Workers need to repetitively lift a load above their shoulders hence, giving extreme strain to the muscle. To overcome this issue, a prototype was designed and developed to directly transfer FFB. The device is equipped with a hydraulic system and powered by a battery. There is a need to assess the overall performance of the device compared with the manual. The time taken to transfer a different number of bunches, time taken for total FFB evacuation, productivity and battery depletion rate was evaluated. Three-wheel transporters were used and a plot with medium-size FFB was selected. The study indicated that the device was able to handle 400 kg of loads in 38.1 s. It was found that by using the device, unloading activity will only consume about 4% of the total FFB collection time. The study showed that the machine helped the workers by reducing their time to complete the task by 35% more than the manual. In conclusion, the device functioned and performed as it is designed. Workers can now directly transfer the FFB into a bin at a reduced time.

一种鲜果串装载倾卸装置的性能评价

手动装载油棕新鲜水果束(FFB)包括用铁钉将束捡起并将其放入垃圾箱或拖拉机拖车中。工人们需要在肩膀上反复举起重物，这给肌肉带来了极大的压力。为了克服这个问题，设计并开发了一个直接传输FFB的原型。该装置配有液压系统，由电池供电。有必要评估设备的整体性能与手册进行比较。评估了转移不同数量束所需的时间、总FFB疏散所需的时间、生产率和电池耗尽率。采用三轮运输车，选择一个中等大小的FFB小区。研究表明，该设备能够在38.1秒内处理400公斤的负载。通过使用该设备，卸载活动只会消耗大约4%的总FFB收集时间。研究表明，机器帮助工人完成任务的时间比手工减少了35%。总之，该装置的功能和性能与设计一致。工人现在可以在更短的时间内直接将FFB转移到垃圾箱中。
