Double Drum Hoist Winch is mainly composed of electric motor, reducer, reel (or friction wheel), braking system, depth indication system, speed limit system and control system, and is driven by AC or DC motor. According to the working principle of the lifting wire rope, it is divided into winding Double Drum Hoist Winch and friction Double Drum Hoist Winch. The winding type Double Drum Hoist Winch has two types of single reel and double reel. The steel wire on the reel is similar to the ordinary winch. Most single cylinders have only one wire rope and are connected to a container. Each drum of the twin drum is equipped with a wire rope to connect two containers, one container is raised during operation and the other is lowered. Double Drum Hoist Winch is mainly used in mines with an annual output of less than 1.2 million tons and a depth of less than 400 meters. Friction Double Drum Hoist Winch's lifting rope is suspended from the friction wheel, and the container is raised by friction with the friction wheel pad. One end of the lifting rope is connected to a container, or one end is connected to the container and the other end is connected to a balance weight. The friction type Double Drum Hoist Winch is divided into two types according to the arrangement: tower friction type Double Drum Hoist Winch (machine room is set on the top of the shaft) and floor friction type Double Drum Hoist Winch (machine room is set directly on the ground). According to the number of lifting ropes, it is divided into single rope friction Double Drum Hoist Winch and multiple rope friction Double Drum Hoist Winch. The latter has the advantage that thinner steel ropes and smaller diameter friction wheels can be used, so the unit is small in size and easy to manufacture; fast speed, large lifting capacity, and good safety. This type of crane is used in most shafts with an annual output of more than 1.2 million tons and a depth of less than 2,100 meters.
About Double Drum Hoist Winch:
This is a large crane. Motor drive The motor drives the wire rope to drive the container up and down in the wellbore to complete the transportation task. Double Drum Hoist Winch was developed from the original water lifting tool. Hyundai Double Drum Hoist Winch has a large number of upgrades, high speed, high security, and has developed into a fully automatic heavy mining machine controlled by an electronic computer.
