Cantilever Gantry Crane

A cantilever gantry crane is a specialized lifting equipment designed for efficiently handling materials in various industrial settings. What distinguishes a cantilever gantry crane is its unique structure, featuring a horizontal cantilever beam extending beyond its supporting legs. This design allows the crane to reach and lift loads located outside its framework, making it particularly useful for scenarios where obstacles or obstacles limit direct access.
