I studied the building is JM winch. JM series isa slow hoist. During the design of the main part of the hoist drive, work and the winch the main part of the design. In part using a transmission gear reducer and two open-gear transmission, the working part of the reel is used in welding-reel. The main characteristics of the hoist structure is simple, easy to operate. The primary function of this machine: the construction industry in the cold-drawn steel weights increase, the skidding in forestry work, while in the water and electricity, agriculture and other industries can be used. The development trend of such machines tobe large, the use of advanced electronic control, portable winch, non-power devices in the direction of the winch.
