Double drum lifting equipment

Two rolls have a connection with the shaft in different ways , one of which rolls through the wedge bond or liftech winch hoist thermal loading and spindle fixedly connected together, called fixed roll , also known as the death roll ; another roll slide mounted on a spindle , the spindle is connected via a clutch , so called swimming volume reduction, also known as live roll. The purpose of this structure is given to the production process to enhance the mine an elastic elongation of the rope under the load terminals , to enhance the level or multi- level conversion ascension possible relative liftech wind tubine hoist rotation between the two reels need to adjust rope length , making the two containers are aligned with the wellhead and the bottom level.
