The hoist is an important mechanical equipment for the construction unit. The use of some single-speed electric or motorized hoists has certain limitations. At present, the hoisting machine of our basic company system must have the following characteristics: First, it can meet the requirements for land and water operations. Second, can be suitable for the edge, the lack of energy in the area of operational requirements. Third, in order to enable the winch to be used on board, the prime mover must use a diesel engine.
