The hot chamber dynamic manipulator is widely used in the spent fuel treatment plant, which can be used for the preparation and temporary storage of high-level radioactive waste, and also for the disposal of high-level nuclear waste. The hot chamber dynamic manipulator system is mainly composed of power arm, big car and its driving device, telescopic cylinder system, camera system, cable and its penetration, running track, emergency recovery system, replacement device, operating tools and control system (safety limit) and other modules. The power manipulator can be applied in the environment where there is radiation or human cannot be present at the scene, and complete the inspection, assembly, disassembly, welding, transportation, decontamination, storage, repair, decomposition and other operations of the target parts through remote control and video system. It has the characteristics of remote operation, large coverage, strong flexibility, flexible operation, large force, radiation resistance and so on.
