Installation requirements for group hoist electric hoist
Electric hoist is a kind of compact structure, light weight, easy to use and repair, and it is a commonly used lifting equipment in industrial and mining enterprises, railways, docks, and warehouses. The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. Its disadvantages are: large length dimension, large width dimension, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low-voltage control, which increases the safety of the control system. The equipment can lift heavy objects on single-beam bridge group cranes or straight and curved monorail suspension I-beams, or (fixed type) can directly place the hoist equipment on a fixed support for straight or different viewpoints. Used for lifting. The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. Its disadvantages are: large length dimension, large width dimension, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low-voltage control, which increases the safety of the control system. The equipment of electric hoist has requirements for quality:
The wire rope and hook equipment should be wound according to the equipment skill requirements. The wire rope head, reel body, hook fixing method, and the tightening degree of fasteners should be strictly in accordance with the specifications of the document.
A comprehensive inspection should be carried out after the equipment is completed, and the inspection contents are as follows:
Whether the electrical equipment of the electric hoist is suitable for the current change and working voltage of the equipment location.
Whether the electrical connection is correct and stable.
Whether the movement of the limit device is correct, sensitive and reliable.
Is enough lubricating oil added?
When choosing the power cord, you must ensure that the power of the motor is not less than 90% of the additional voltage.
The wire rope lock must be firm.
