Product Description
50t Movable Double Girder Gantry Crane

Gantry crane is a large-scale lifting equipment with a gantry-shaped frame, which operates on ground tracks or is fixed in a specific area, and uses lifting mechanisms, traveling mechanisms, etc., to realize the vertical lifting and horizontal transportation of heavy objects, and is widely used in factories, ports, storage yards and other places.

Double Girder Gantry Crane Structure

As a heavy-duty main model of gantry cranes, the double-girder gantry crane is characterized by its gantry main girder adopting a double-track structure composed of two parallel load-bearing steel beams. It achieves wide operational coverage via independently operating lifting trolleys and leverages stronger rigidity.
