The power manipulator is mainly used to assist workers in handling and assembling, and is a power handling equipment that reduces labor intensity. During the handling process, the equipment is controlled by a logical gas circuit, intelligently senses the weight of the load, and converts the weight of the heavy object itself into only 1% of the manual operating force. The "zero gravity floating operation" easily realizes the movement, handling and assembly of heavy objects at any position in the operating space, and safely and efficiently solves technical problems in the field of industrial handling and assembly. Non-standard customized slings can complete the actions of grabbing, handling, flipping, lifting, docking, etc. of workpieces (products), and quickly and accurately assemble heavy objects in pre-set positions, or complex operations on the assembly line. It is an ideal power and transfer equipment for material loading and unloading and production assembly, which can save manpower and improve efficiency for factories.
