ABSTRACT
Crane is used to start heavy materials, transportation, handling and installation of machinery and equipment and other operations, which can reduce manual labor, improve labor productivity and in the production process for some special process operation, mechanization and automation. Lifting mechanism includes a motor, brake, reducer, drum and pulley. Motor through reducer, driving drum rotation, so that the wire rope around the drum or from a roll down to lift heavy loads.
In this paper, ten tons crane hoisting mechanism to do the design calculations to determine the transmission scheme lifting mechanism, hoisting mechanism to determine the working level of the main components of the hoisting mechanism drum, wire rope, wire rope winding system pulleys, motors, United coupling, reducer drives the design calculations, validation reel wall stress, stress reel, hook device is configured to determine program, hook beams, pulley shaft calculation. Hoisting mechanism for running processes, including the lifting speed, lifting and braking time calculations and checking.
