Practice a hoist. Construction units, to hoist should be installed on a flat solid, good foundation vision hoist price, body and must be firmly anchor. Requirements hoist should be perpendicular to the centerline of the guide pulley alignment hoist manufacturer, hoist pulley distance generally should not be less than fifteen meters. 2. Before transfer loading operations, should check the rope, clutches, brakes, insurance ratchet drive pulleys, etc., to determine the safe and reliable operation only. Wire rope on the drum must be neat, jobs need to retain a minimum of three times. When the job, it was not allowed to cross the wire rope hoist by preventing accidents. 3.

Jobs sudden power failure, should immediately pull the knife, and the delivery of objects down. Hoist winch for the spreader and the gate is connected to the transmission system so that the winch drum around, put the cable through the gears so as to drive a mechanical lift (Figure 2) with a rope or wire rope pulley block, also called fixed rope hoist . It is relatively simple and easy to manufacture structure, easy maintenance and repair, are widely used in various types of gate opening and closing. Hoist winch into twin-lift and two single hanging point. Twin-lift hoist winch is connected to the shaft by two single hanging point hoist connected together for synchronous operation, can be made into one side or both sides of the drive drive. Hoist winch usually 一扇 gate with a hoisting equipment, mounted on top of the tank above the gate of the pier. China has produced and put into operation the hoist winch capacity has been reached: Inception force 6000kN, opening and closing stroke 30m, and open the door force 4000kN, hoist travel 120m.
