XCMG Factory Bridge Erecting Machinery Traveling Cranes Machine for Construction

The bridge erecting machine is a special construction machinery that hoists prefabricated reinforced concrete (or prestressed concrete) beam slabs and places them on bridge bearings (piers).

It is mainly composed of the main structure, the trolley system, the hole-passing system and the power system, etc., and can be divided into types such as single-girder bridge-erecting cranes, double-cantilever bridge-erecting machines, and double-girder bridge-erecting machines.

Working principle of the bridge erecting machine The working principle of the bridge-erecting machine is to lift the beam slab through the trolley system, then move along the main structure to the designated position, and then accurately place the beam slab on the pier through the hole-passing system. The appearance of the bridge-erecting machine has greatly improved the efficiency and quality of bridge construction and reduced the investment of manpower and material resources.
