Electric motor, reducer, hand brake, coupling, driving pulley and working brake, etc.
Based on the operating speed, it is divided into three categories: single-speed shuttle car, double-speed shuttle car and frequency-conversion shuttle car.
Single-speed shuttle car——runs at constant speed during material transportation no matter full load or empty load.。
Double-speed shuttle car——runs at slow speed with load and fast with empty load.
Frequency-conversion shuttle car?——the frequency-converting device changes the output speed of the driving system by adjusting the power frequency of the electric motor. It can achieve speed adjustment, soft start and soft stop to some extent. Within the speed range, the user can change the speed as per actual need. But the frequency-conversion shuttle car has the drawbacks such as high rate of frequency-conversion failure, harmonic wave interruption and contamination to the control signal of surrounding power grid and devices, large heat emission and large size.
