Electric wire rope hoist is a kind of small lifting equipment with the advantages of compact structure, light weight, small volume, strong universality of parts and convenient operation, etc. Welding, such as the installation and movement of various large and medium-sized concrete, steel structures and mechanical equipment, suitable for construction and installation companies, civil engineering and bridge construction in factories and mines, electric power, ships, automobile manufacturing, construction, highways, bridges, metallurgy, mining , slope tunnel, shaft management and protection and other infrastructure engineering machinery and equipment.Visit Nybon’s main page–professional lifting equipment supplier.

Electric wire rope hoist also belongs to special lifting equipment, which can be installed on I-beams alone or on electric or manual single-beam, double-beam, cantilever, gantry and other cranes. The motor generally uses a conical motor, which automatically locks the brake after stopping. The wire ropes matched with it include phosphating-coated wire ropes, galvanized wire ropes and smooth wire ropes.

The components of electric wire rope hoist are: motor, transmission mechanism, drum and wire rope. According to the different positions of the motor and the reel, it can be roughly divided into four types.

(1) The electric hoist whose motor axis is perpendicular to the axis of the reel adopts a worm gear transmission device, which is large in width, bulky in structure, low in mechanical efficiency, and difficult to process. There are no manufacturers of this type of construction anymore.

(2) The electric hoist with the axis of the motor parallel to the axis of the reel has the advantage of being small in height and length. The disadvantages are large width, grouping, and complicated manufacturing and assembly. The track has a large turning radius.

(3) The electric hoist with the motor installed in the drum has the advantages of small length and compact structure. The main disadvantages are poor motor heat dissipation conditions, poor grouping, inconvenient inspection, installation and maintenance of the motor, and complex power supply devices.

(4) The electric hoist with the motor installed outside the drum has the advantages of good grouping, high degree of generalization, easy to change the lifting height, and convenient installation and maintenance. The disadvantage is: the length and size are large.

The parts of wire rope electric hoist can be roughly divided into:

1. Reducer 2. Reel device 3. Hoisting motor 4. Electric trolley 5. Cone brake 6. Adjusting nut 7. Rope guide 8. Coupling 9. Hook device 10. Control button 11. Hollow shaft 12. Box 13. Sealing ring 14.09 Gear 15.06 Gear shaft 16.05 Gear shaft 17.04 Gear shaft 18. Ball bearing 19. Needle bearing 20. Box cover 21. Breathable plug

The functions and functions of each part are as follows:

Reducer: It adopts three-stage fixed-axis helical gear transmission mechanism. The gears and gear shafts are made of alloy steel with heat treatment. The box body and box cover are made of high-quality cast iron, with tight assembly and good sealing.

Control box: It is a device that can cut off the main circuit in an emergency and has an upper and lower stroke protection section fire limiter.

Wire rope: It is a heavy-duty wire rope, which ensures durability. Conical motor: The hoisting motor adopts a large dynamic torque conical rotor to brake the asynchronous motor, and no external brake is required.

Button switch: Hand-operated, light and flexible, divided into two modes: corded control and cordless remote control.
