Hoist equipment installed before the transfer operation
Hoist equipment installed before the transfer operation, check the wire rope, clutches, brakes, insurance ratchet,electric chain hoist and trolley drive pulleys, etc., to determine the safety and reliability before operation. Wire rope on the drum must be arranged in neat rows, the job should be retained at least three times. When the job, it was not allowed to cross the wire rope hoist by preventing accidents.
Hoist equipment including motor, hoist, chassis, shields and other components; using three deceleration mode,strong electric winch with spiral pay transmission output torque greater. Hoist steel supporting civil overcome irregularities in order to reduce overall noise and vibration.hoist equipment with hydraulic hoist, winch hoist, doors, hand wheel hoist, hoist flashlight, hand hoist, screw hoist, dual crane hoist and so on.

The basic classification of steel wire rope electric hoist
Part of monorail wire rope hoist are: motor, drive mechanism, the drum and a steel wire rope. The motor and the reel mutually different positions can be divided into four types.
(1) the electric hoist motor axis perpendicular to the drum axis with worm gearing, width of large size, heavy weight, low mechanical efficiency, processing more difficult. There is no manufacturers of this type of product.
(2) the motor axis parallel to the drum axis electric hoist, the wire rope electric hoist has the advantages of small size and length of the height. The disadvantage for large width, grouping, complex manufacturing and assembly. Orbital radius.
(3) the strong electric winch motor mounted on the inside of the drum, the utility model has the advantages of compact structure, small size. The main drawback for motor cooling condition is poor, packet difference, inspection, installation, motor maintenance inconvenience, power supply device complex.
(4) the electric hoist motor mounted on the outside of the drum, the advantages of good for grouping, high level of generalization, changing the lifting height is easy, convenient installation and maintenance. Its shortcomings: large size.
