QY type insulated double beam bridge crane is suitable for factory workshops that produce electrolytic non-ferrous metal materials such as aluminum and magnesium. This crane consists of four parts: box bridge, large vehicle operating mechanism, small vehicle, and electrical equipment. In order to prevent the current on live equipment from being transmitted to the crane through the lifted components during work, which could endanger the driver's life and equipment, several insulation devices have been installed at appropriate locations on the crane. This crane operates on a heavy-duty system. The main lifting mechanism is equipped with dual brakes. All institutions operate from the driver's cab.

(1) The bridge adopts box shaped main beam and automatic submerged arc welding.

(2) The small car adopts a new conductive device of I-beam track cable, which is reliable.

(3) The lifting mechanism may also be equipped with another set of devices as required. Increase reliability.

(4) Standardization, serialization, and universalization of components.

(5) The control room has a wide field of view, and all mechanisms are operated in the control room, making work and operation flexible
