KBK crane is a single-girder crane with suspension system. But it does not use I-beam, but consists of C-shaped steel and pendants. The structure is relatively simple and the carrying capacity is limited. Based on the customer’s working environment, we recommended the KBK crane to the customer. The lifting mechanism used a low-clearance electric chain hoist, which solved the problem of limited factory height. kbk crane adopts modular design structure, which is very convenient and quick to disassemble. The overall scheme design saves customers a lot of money and improves track operation efficiency.
