Skills Of Purchasing Diesel Winch In China

The diesel winch realizes the scheme of double variable transmission system of variable speed motor and transmission. Most of the existing tower crane lifting mechanisms use variable speed motor speed reducer, and the transmission ratio of diesel winch reducer is fixed, 

so the variable number of variable speed motor determines the speed gear, and the maximum far pole ratio of common three speed motor is 4 / 6 / 24. It cannot meet the requirements of the standard for the ratio of the maximum speed to the minimum speed of the tower crane. Therefore, only relying on motor speed change and changing magnification can not meet the standard requirements, but must be supplemented by speed change mechanism.
