Gantry Cranes
Gantry cranes are similar to overhead cranes, but instead of being suspended from a beam or support structure, they are supported by a gantry, which is a structure that consists of a frame supported by legs or pillars. Gantry cranes are typically used in outdoor settings, such as docks, yards, and construction sites, and are often used to move heavy equipment or materials.
Single girder cranes:
These cranes have a single beam that supports the trolley and hoist. They are suitable for lighter loads and smaller spans.
Double girder cranes:
These cranes have two beams that support the trolley and hoist. They are more suitable for heavy loads and longer spans.
