The rubber tyred gantry crane is a kind of storage yard handling equipment gradually developed since the 1970s. It not only has the performance of large storage yard and high operation efficiency of the common rail type gantry crane, but also has the mobility of general rubber tyred mobile machinery. It can be flexibly mobilized in a large range, and has the characteristics of high space utilization, high productivity and full storage yard mobility.

With the development of small and medium-sized multi-purpose wharves in inland rivers and the emergence of a large number of third-party logistics storage and transportation yards around the port, the demand for rubber tyred gantry cranes is increasing. In the actual equipment selection, these multi-purpose and small-scale storage yards can not afford to buy, manage and use professional rubber tyred gantry cranes. However, it is difficult for general lifting equipment to take into account the working requirements of loading, unloading, stacking and handling of multi-purpose storage yards, so these small and medium-sized multi-purpose storage yards face many difficulties in the selection of loading and unloading equipment.

The multi-purpose rubber tyred gantry crane is a storage yard machine developed to meet the domestic market demand. The multi-purpose rubber tyred gantry crane reduces the dead weight of the equipment, reduces the wheel pressure, and the cost is only 1/3 of that of other rubber tyred hoisting machinery and equipment, and greatly reduces the infrastructure investment of the storage yard. Therefore, it not only has the characteristics of strong mobility and flexible movement of the professional rubber tyred gantry crane, but also has the advantages of simple structure, low quality, low investment and easy maintenance.
