LH  electric hoist double beam crane is composed of four parts: box bridge, truck operating mechanism, car and electrical equipment. The fixed electric hoist is installed on the trolley frame as a lifting mechanism. The trolley runs with LD type transmission, and the truck runs part of LD type transmission and QD type transmission. The structure is simple and light, with the overall height is small, light weight and other characteristics, suitable for small and medium weight range of factories, mines, workshops and warehouses and other workplaces.

Operation mode with ground handle, wireless remote control and driver’s cab three operating forms. The cab has two types: open and closed

Feature description
The double beam structure makes the crane bridge have sufficient strength, stiffness and stability.

The box girder design fully meets the requirements of strength, stiffness and stability.

The simple design of the end beam can be easily connected to the main beam by high-strength bolts.

CD or MD wire rope electric hoist used as lifting mechanism.

Run motor soft start, ground control.

The use of dual motor independent drive device, reduce track bite wear, reduce the possibility of wheel off track failure.

The motor is controlled directly by the contactor, allowing the motor to achieve single and dual speed and commutation control.

The frequency converter is used to change the frequency and voltage of the motor power to realize the motor speed control function.
