Complex building conditions require specialized solutions that are easily implemented by underslung bridge travelling cranes. The gantry rails are mounted on the ceiling instead of free-standing alone or building columns. Therefore, the best results can be obtained even under a narrow space and difficult conditions.

Huada Heavy Industry underslung bridge travelling cranes has optimized the existing building width by adopting a very small side approach size and a customized main beam cantilever. It is also possible to optimize the highest hook position by placing a main beam between the end carriages.

One type of underslung bridge travelling crane, low headroom light duty (single beam hung crane) is traveling under I-section or H-section steel beam, using CD1, MD1 electric hoist for hoisting equipment, adopts ground controlling, is a light duty rail traveling crane with trajectory which applies to and used at Mechanical, Assembling Sites and Warehouses.
