motorized mobile gantry crane

The motorized gantry crane is a lifting and handling device which has two legs extended by vertical posts supporting a sliding girder system.

Main Beam: A horizontal load-bearing structure—typically an I-beam or box girder—that supports the hoisting trolley and the load.
Support Legs: Vertical support structures—commonly A-shaped, U-shaped, or box-shaped—that provide stability.
Traveling Mechanism: Equipped with swivel casters, solid tires, or rail wheels at the base of the legs to facilitate movement and steering.
Hoisting System: Fitted with a manual or electric hoist (or winch) to execute vertical lifting and horizontal movement.
Control System: Features a push-button pendant or wireless remote control for simple and convenient operation.
