Hoist

  With a compact, light weight, small size, parts versatility, easy operation, it can be installed separately on the beam can also be installed in electric or manual single-beam, dual-beam, cantilever, gantry the use of a crane.
electric wire rope hoists structure
Part of the wire rope hoist are: motor, transmission, drum and sprocket. The mutual positions of the motor and the spool can be roughly divided into four different types.
(1) The motor axis is perpendicular to the axis of the hoist drum using worm gear, large width aspect size, structure, heavy, low mechanical efficiency, more difficult process. Manufacturers currently have no such structure type of product.
(2) motor axis parallel to the axis of the drum hoist, the advantage of small size, height and length. The disadvantage of a large width dimension, of the packet, manufacturing and assembly complexity. Track turning radius.
(3) The motor is mounted inside the drum hoist, the advantage of a small length dimensions, compact structure. Its main drawback is the motor cooling conditions are poor, poor groups, inspection, installation, maintenance, motor inconvenience, power supply unit complex.
(4) motor mounted on the outside of the drum hoist, the advantage is for the group is good, high degree of common, easy to change the lifting height, easy installation and maintenance. Its disadvantages: large length dimensions.
