Abstract
Electric hoist  is one of the main models of lifting equipment. It is mainly formed by the reducer, running organizations, drum installation, hook device, the coupling stopper, conical rotor motor and other components. According to the design task demands, this book mainly Against to 3t mobile electric hoist single hook selection and determination of the overall program, and then design the transmission system.
According to the requirements and objectives of the design, reference CD-type electric hoist on the first take the 3t mobile electric hoist with the single hook for the process analysis, select reasonable organization and assembly programs, then design the shape of the reducer and electric motor, selection of wire rope and strength checking, reel The parameter calculation and checking, and calculate the gear transmission ratio, to determine the parameters of each gear, the strength calculation, select a reasonable bearings, keys, bushings and other components, to draw general assembly drawing. Finally, the tire type flexible coupling made some brief elaboration.
Key words: lifting equipment;Electric hoist;Rope drum;Reducer
