The rubber tyred gantry crane is a large-scale lifting equipment widely used in ports, docks, logistics parks, construction sites, etc. It combines the structural features of a gantry crane with the flexibility of a tire-driven walking mechanism, enabling free movement without the need for laying tracks, which significantly improves operational efficiency and site adaptability.
The rubber tired gantry crane is mainly composed of a gantry structure, a lifting mechanism, a running mechanism, an electrical control system, and a tire-driven walking device. The gantry structure usually adopts box-type beams or truss structures to provide sufficient strength and rigidity to support the lifting load. The lifting mechanism is responsible for the vertical movement of the goods, typically consisting of an electric motor, reducer, brake, drum assembly, and steel wire rope. The running mechanism drives the entire crane to move on the horizontal plane, and the tire-driven walking device is its core, allowing the crane to freely travel on hard ground without relying on tracks.
RTG cranes are particularly suitable for scenarios where the operation location needs to be frequently moved, such as temporary storage areas, multi-commodity docks, and construction sites that require rapid deployment.
