electric wire rope hoist - Liftech component

Wire rope hoist component are: motor, transmission, drum and wire rope. Mutual position of the motor and the reel to be roughly divided into four different types.
(1) The motor axis is perpendicular to the axis of the reel hoist using worm gear, large width aspect size,small electric hoist structure, bulky, low mechanical efficiency, more difficult process. Manufacturers have no such structure type of product.
(2) parallel to the axis of the roll axis motor is an electric hoist, the advantage of a small height and length dimensions. Its disadvantage is that the large width dimension,permanent magnetic lifter of the packet, the manufacturing and assembly complexity. Track turning radius.
(3) motor mounted on the reel inside the electric hoist, the advantage of a small length size, compact structure. Its main disadvantage is that the motor cooling conditions are poor, poor grouping,lever block inspection, installation, maintenance, motor inconvenience, power supply unit complex.
(4) mounted on the outside of the drum motor hoist, the advantage is for the group is good, high degree of common, easily changing the lift height for easy installation and maintenance. Its disadvantages are: large length dimension.
