Is there a difference between single girder bridge crane and double girder bridge crane?
- Apr 03, 2018 -

As the name suggests, the single beam bridge crane has a transverse main beam, which is located on the top of the large field column. It hangs on the electric hoist, and the big car is equipped with electric hoist to move up and down, around and back, mainly with LD type single beam bridge crane. Two girder bridge cranes consist of two main girders. The top ones are hook trucks, gourd cars or hoists. Double girder bridge crane mainly has 1.QD type double beam bridge crane: the top running is the hook car, the working mechanism is higher, the tonnage is higher, and the 2.LH double beam bridge crane: the top running is the gourd car, the working mechanism is not very high relative to the QD type double beam bridge crane, but the general workshops and wharf work are possible; so when the weight is lifted to a certain extent QD type double beam bridge crane should be selected for tonnage.
