Brief Description
The double girder bridge crane is made up of box shape bridge girder, hoisting trolley, crane traveling mechanism and electric system. The typical features of this double girder crane include light dead weight, low wheel load, small outline dimension, reliable performance and convenient operation.
Compared with traditional cranes, this lifting machine comes with smaller critical distance between hook and the wall. In addition, the lowest headroom enables it to be closer to the roof, thus effectively improving lifting height. Therefore, depending on the light dead weight and low wheel load, the double girder overhead crane can largely save covering space of workshops and broaden functions.
Above all, this industrial hoisting equipment can save you a huge amount of money from initial construction investment, long-term heating and air conditioning as well as other maintenance costs. Currently, YUNTIAN has been well known as a specialist bridge crane manufacturer in China. We are always committed to producing and distributing the most superior, efficient and cost effective overhead cranes.
