Free Standing Bridge

1. Product Introduction:

 

The electromagnetic double-beam crane is composed of five major parts: bridge, trolley (equipped with lifting mechanism and operating mechanism), electromagnetic crane operating mechanism, electrical equipment, electromagnetic chuck system (electromagnetic double-beam), and rotating mechanism. The hoisting mechanism, trolley operating mechanism, rotating mechanism and crane operating mechanism are the various working mechanisms of the crane. Each mechanism is equipped with a separate electric motor for its own drive. The operation of each mechanism of the double-girder crane is controlled in the operating room. The control room is suspended under the transmission side platform near the end beam of the crane bridge. The control room is equipped with control equipment of various mechanisms and protection switchboards, emergency switches, bell buttons, etc.
