Conventional gantry cranes are used for installation on roads or railways. It lowers a cable connected to a hook point on the storage container. The gantry crane then lifts the container and moves it further for stacking or loading onto a trailer for shipment. Rubber tyred gantry cranes also work on a similar principle. The difference is that the entire device can be moved from one location to another.

A semi gantry crane consists of a bridge, a trolley running mechanism, a trolley running mechanism and a lifting mechanism, which are basically the same as a overhead crane. This semi gantry crane is a combination of a overhead crane and a gantry crane.

The main structure of the double girder overhead crane consists of a box steel with two beams or a profiled steel with a mobile electric carriage. The lifting system consists of a winch or a wire rope hoist, running on the beams as required, allowing horizontal movement.

Rail mounted gantry cranes are composed of main beams, rigid and flexible gantry legs, running trolleys, lifting mechanisms, trolley running mechanisms, electrical systems, operating cabs, etc. According to the yard operation process, the cantilever in the direction of the single gantry leg or the double gantry leg becomes a single cantilever or double cantilever model, and the non-cantilever model becomes a cantilever-free model.

The underhung crane is light in weight and has good performance. For different needs, as a leading manufacturer and supplier of professional bridge cranes, we can provide customers with high-quality products and the best service.

The portable mobile jib crane can be operated in any direction to the desired location, and the electric hoist can travel on the cantilever, which is suitable for occasions where the heavy object needs to carry or rotate.
