This set of vehicles (3 units) is used for transfer in the workshop of the docking platform. It has the advantages of omnidirectional movement, high positioning accuracy (0.5mm), high linkage accuracy, and wide range of activities. This mode of transportation replaces the original rail transportation and manpower-propelled transportation methods, and solves the problems of long transportation time and low reset efficiency, while taking into account the safety of personnel and aircraft protection. The original multi-person operation, low transfer efficiency and complex operation process, has been transformed into an efficient and rapid realization of the rapid transfer of the dock when the aircraft is out of the warehouse.
