Features of 20 ton overhead crane

Double girder 20t crane is a great solution designed to carry medium and heavy duty loads. By using two adjacently positioned beams, traveling bridge crane offers improved support for the goods being handled, allowing the movement of larger capacities.

Product detail description:

1. Strong beams: the crane beams are of welded construction.
This result in lower dead weight with a high degree of vertical and horizontal rigidity and smaller wheel loads.
2. End carriage: crane traveling system, motor reducer-wheel driven system. The motor uses soft start motor which results in very stable starting.
3. Durable performance and high efficiency.
4. Modern cabin control with air conditioner can separate operators from harsh environment.
6. Long service lifespan with a low-maintenance.

Hook often hangs on the wire rope of lifting mechanism by means of pulley block and other components.

The reel group is a part of the winding rope in the lifting mechanism and the traction mechanism.

The brake has the function of stopping the falling of the suspended object and stopping machine movement.

Overhead cranes mainly have main girders and end beams.

After the crane is introduced into the power supply from outside, it will be allocated to the various electrical parts through the distribution box, and the electrical protection of these electrical equipment is necessary.

For reducer, its main function is to transfer the high speed of the motor into the actual speed required by the crane’s various mechanism, and to obtain a large torque.

An electric motor is a device that converts electrical energy into mechanical energy, so that the crane can run normally vertically or horizontally.
