DESIGN AND FABRICATION OF HAY BALE LIFTERABSTRACTHay bale lifter is one of the material handling equipments used to lift and lower the load. It helps a dairy farmer for lifting the load (hay bales) in to the barn loft. Worm gears are used to transmit power between two intersection shafts which are right angels to each other. The gear box output shaft is coupled to the winch drum shaft. The drum acts as a capstan around which is wound a rope that has forged hook at its end. The farmer can lift the hay bales with little effort. This is caused by gear ratios inside the lifter. Thus it simplifies lot of load lifting works. It can be easily operated by an amateur. A lifter can be built as one integral-package unit, designed for cost-effective purchasing and moderate use, or it can be built as a built-up custom unit, designed for durability and performance.BLOCK DIAGRAM
