Hoist motor uses a unique turbine rod design which contains motor, brakes, reducer, and rope pressing device etc. When suspended platform rises or falls, the hoist does not roll or release wire rope. Power comes from friction between rope wheel and wire rope.
As a building maintenance suspension platform hoist, its motor block torque is not less than 180% of the rated torque. It should have good rope wearing performance and should not get stuck or blocked. All rotating exposed parts should be provided with a hood or protective device. The brake must be suspended with a rated load of 125% and stop running within a slip distance of no more than 100mm.
The hoist and its accessory is important component of window cleaning suspension platform. There are two types, one is driven by electromagnetic brake three-phase asynchronous motor, after secondary deceleration drive wire rope conveyor so that working platform move up and down, another is also three-phase disc motor driven by electromagnetic braking, when deceleration, coaxial transmission drives wire rope working to move suspension platform up and down.
