Part of the wire rope electric hoist
Part of the wire rope electric hoist：Motor, transmission, roll and sprocket.
The mutual position of the motor and reel can be broadly divided into four types.
(1) perpendicular to the motor axis in the roll axis of the electric hoist using the worm gear, the size of the width of the area is large, a bulky structure, the low mechanical efficiency and processing more difficult. Has no product manufacturers this structure type.
(2) The motor axis is parallel to the roll axis electric hoist, the advantage of height and length dimensions. Its disadvantages for the width dimension of the packet, and manufacturing and assembly complexity. Track turning radius.
(3) electric hoist motor mounted inside the drum, the advantage for the length of the small size, compact structure. The main drawback to the motor heat, poor, poor packet, inspection, installation, maintenance Motor inconvenience, complexity of the power supply unit.
(4) electric hoist motor out of the reel, the advantage for the grouping is good, high level of generalization, change from the lift height, easy installation and maintenance. The disadvantage: the length size.
