Product Description

Where are Gearboxes on the overhead Crane hoist?

1.Trolley (Cross Travel) Mechanism

The trolley drive on an overhead crane moves the hoist along the bridge girder horizontally. A gearbox is used here as well to convert the high-speed motor rotation into the necessary low-speed, high-torque motion that drives the wheels or rollers to move the trolley across the crane’s bridge.

2. Bridge Travel (Longitudinal Travel) Mechanism

This is the part of the crane that enables the entire bridge to travel along the runway beams. Similar to the trolley mechanism, there's a gearbox attached to the motor that controls longitudinal movement. It adjusts the motor's speed to provide smooth and powerful propulsion along the length of the crane's track.

3. Lifting or Hoisting Mechanism

The hoist gearbox is a crucial component in the lifting mechanism of the crane. It's connectedto the electric motor and reduces the high-speed rotation from the motor to a lower speed but higher torque output to lift and lower heavy loads safely and precisely. The hoist gearbox usually works together with a brake system and a wire rope drum or chain hoist.

Safe, Reliable, and Strong

Based on your load specifications, lifting speed, and FEM level, our lifting technical experts will provide you with the best configured drive system. The FEM level mainly emphasizes the quality of the driving device. Under the most competitive conditions, the drive device you choose will have a longer service life. Even outside of our regular product portfolio, you can collaborate and communicate with us. Even in different voltage conditions and harsh usage environments, powerful drives can operate reliably and safely. Adopting soft start and dynamic start curve to ensure larger start Boost and maximum torque.
