ABSTRACT
Electric hoist lifting equipment is one of the main models. It is mainly made up of
reducer, running-device, roll device, hook device, coupling limit, cone-shaped rotor motors,
and other components. This paper mainly studies hook 3 t-mobile electric hoist, It is widely
used by machinery equipment company and terminals or other places. Based on the design
requirements of the task, carry out a single hook 3 t mobile electric hoist the options and
determine the overall plan, then the transmission system design. According to the first
design requirements and objectives, reference CD-based electric hoist to 3 t-mobile electric
hoist hook for process analysis, rational choice and the assembly program, and then the
appearance reducer and motor design, the choice of wire rope and intensity of checking, the
reel Parameters and checking, and then calculated the gear transmission ratio to determine
the parameters of the various gear, strength calculation ,select a reasonable bearing, bond,
bushings and other parts, then draw general assembly. Finally, the tire-flexible coupling
made some simple exposition.
