Design and development of tractor rear loader arrangement for material handling in constructional applications

ABSTRACT This rear loader attachment is developed to minimize the labor work as well as to minimize a time for material handling in various applications like constructional work. It is simple in construction and can be easily attached with the existing rear mechanism of any tractor so no need to develop a new mechanism for rear loader attachment. This attachment is developed to overcome the various limitations which other earth moving equipment have like larger size, heavier in mass generally in tones etc. Rear loader is designed with components which are easily available in market so maintenance and replacement of components is not a problem. Important benefit of this design is that, it allows mower desk to stay attached to the tractor while providing quick engagement-disengament features. Unskilled person can also operate this arrangement very easily as it does not requires any special training which requires while working with other machines like lathe machine. The loader arm and bucket assemblies are completely detachable from the tractor in landscaping task. This rear loader attachment also allows for a greater load carrying capacity and lift range. It can pick up a load up to 120 kg to 150 kg and has enough lift to be able to put loads of mulch, soil and gravel. Various models of tractors like Arjun (605), Mahindra (575), Swaraj (744), Sonalika (855) Select tractor-Arjun (605) can use this rear loader attachment as accessory without changing its actual mechanism at rear side. It can lift weight of material up to 5 to 8 fits. Its capacity of load lifting can be improved by small changes in design and it can be improved up to 200 to 250 kg. Its cost is much lower as compare to other accessories available in market.
