On the basis of absorbing advanced foreign technology, our company developed the JXD trolley luffing mechanism independently for small and medium-sized tower cranes.

This series of trolley mechanism consists of electromagnetic double-speed change-pole motor, semi-concealed planetary reducer, drum, frame and other components.Its characteristics include compact sturcture, high driving efficiency, and low noise, safe and reliable braking, accurate positioning, pleasing in appearance and so on. When users have higher requirements to the trolley running, variable- frequency speed regulation motor with the same interface and relevant electric contol system may be changed to form the variable-frenquency speed regulation trolley mechanism.
