L-type gantry crane is a single-girder gantry crane. Its main structure includes main beam, support legs, ground beam and electrical control part. The lifting mechanism adopts a crane trolley. The trolley runs on one side of the main beam, and the legs are L-shaped.

The structural characteristics of the L-shaped gantry crane are as follows:

It has a simple structure, is easy to manufacture and install, and is light in weight. The main beams are mostly offset rail box frames.
Compared with the double main beam gantry crane, the overall rigidity is weaker, so this form can be used when the lifting capacity is less than 50 tons and the span is less than 35 meters.
The L shape is easy to manufacture and install, has good stress resistance and has low mass.
L-type gantry crane has low cost. Especially suitable for pipelines, lumber companies and logistics. It has unique advantages. It can stack goods within the span and load trucks on the cantilever side, which is suitable for cantilever side loading of pipes with a length of more than 5 meters, which is something that a double-girder gantry crane cannot do.
