European type double girder overhead crane is a new type double beams crane manufacturer, adopts the FEM standard, professional design, structure optimization, meet the requirements of strength, rigidity and stability.

During the design progress, Dongqi Cranes also take into account abut the manufacture, inspection, transportation, installation and maintenance convenience.
The electric trolley hoist adopts European type electric wire rope hoist. As for lifting speed, frequency control makes it has optional speed besides the standard speed to meet customers different requirement.
Light self-weight and compact structure can greatly reduce the cost of warehouse, also spare more room for the lifting height, greatly take advantages of the warehouse.
Capacity: Up to 100 ton. Span: 5 to 35m. Lifting height: 6 to 50m.
Control method: Ground control, remote control, cabin control.
