QD type electric double girder overhead crane is applicable to the workshop of smelting aluminum, magnesium and other electrolytic non-ferrous metal materials. The crane is composed of box bridge, crane running mechanism, trolley and electrical equipment. In order to prevent the current on the live equipment from being transmitted to the crane through the lifted components during the working process, endangering the driver’s life and equipment, several insulation devices are set at the appropriate parts of the crane. This crane is a heavy duty system. To ensure lifting, the main lifting mechanism is equipped with double brakes. All mechanisms are operated in the cab.
Double girder overhead crane configuration is made up of two bridge girders, two end carriages and a hoist with trolley. The hoist travels on top of rails that are mounted to the top of bridge girders. It is widely used for transferring material, goods equipment installation and maintenance in factory, power station, storeroom, warehouse etc.
The double girder eot crane, of a classification group of A3-A7, has a commonly used lifting load 3-250t, so that it is suitable to work in factories, warehouses and freight yards where the ambient temperature is -10-40 degrees centigrade and the relative humidity is not more than 85%. It is prohibited to work in the environment with inflammable, explosive and corrosive gas.
-The bridge adopts box girder, which is welded by automatic submerged arc welding.
-The trolley adopts a new conductive device of I-steel track cable, which is reliable.
-The lifting mechanism of the double girder eot crane can also be equipped with another set of devices according to requirements. Increase reliability.
-Standardization, serialization and generalization of parts.
-The control room has a wide field of vision, all mechanisms are operated in the control room, and the operation is flexible.
