In the hoisting appliance, the structure intensity is improved by using a truss structure. Because the free pulleys and the fixed pulleys are introduced into an actuating unit and the lever principle is adopted, the stroke of a hydraulic cylinder is half of the moving distance of the rope, thus the size of the hydraulic cylinder is reduced. By adopting a method of adding weights, the output power of driving links is reduced. The hoisting appliance realizes flexible transmission due to the adoption of the rope and overcomes the disadvantage of easiness in generation of movement dead spots of a four-rod appliance.
