MG series gantry cranes are patent products specially designed for bridge construction. Because bridge double girder gantry craneconstructions are characteristic of little work batch, large weight, short power supply and frequent worksite changing, combined with advantages of existing machines at home and abroad, ZZHZ designs gantry cranes featuring simple structure, convenient installation, easy operation and energy savings. Advantages of the gantry crane are as below:

(1)   Unique honeycomb girder first made by ZZHZ features light self weight, large bearing load and high wind resistance

(2)     Mature pin connection mechanism, stable and reliable, fast and convenient assembly (it only takes several minutes to put a steel pin)

(3)     Pipe support legs can be disassembled as single pieces as transferring sites, quite convenient to transport

(4)     Min power solves the problem of electricity supply in the wild.

(5)     Travelling mechanism uses frequency converter whose speed is multistage and adjustable, high alignment precision and small impact on the complete machine.
