20t Heavy Duty Electric Double Girder Overhead Crane For Lifting Steel Plate

Introduction:

The double-girder overhead crane is composed of straight rail, crane main beam, lifting trolley, power transmission system and electrical control system, and is especially suitable for material conveying in the plane range with large suspension and large lifting capacity.
The double-girder bridge crane has strong bearing capacity, large span, good overall stability and many varieties, but its own quality is larger than that of the single-girder gantry crane with the same lifting capacity, and the cost is also higher. According to to the structure of the main beam, it can be divided into two forms: box beam and truss. Generally, a box-shaped structure is used.

Features:

The double-girder bridge crane is mainly composed of a bridge frame, a cart operating mechanism, a trolley, and electrical equipment.
