What is a Semi-Gantry Crane?

A semi-gantry crane is a type of gantry crane with a unique design. It has one leg standing on ground rails, while the other side runs on workshop rails (like a bridge crane). This makes it a hybrid between a gantry crane and a bridge crane.

Key Features:

• Saves Space: Uses factory columns and overhead rails, leaving more floor space free.

• Works with Bridge Cranes: Can be used alongside bridge cranes in the same workshop.

• Cost-Effective: Needs fewer supports than full gantry or bridge cranes, lowering costs.

Best Uses:

• Light to medium lifting tasks (loading goods, equipment maintenance, factories, docks).

• Small workshops (handles a few tons) to heavy industries (supports hundreds of tons).

Installation Note:

Since one side runs on ground rails, ensure enough space and clean tracks for smooth operation.
