Wire rope electric hoist

Wire rope electric hoist is a kind of small lifting equipment with the advantages of compact structure, light weight, small size, strong parts versatility, convenient operation, etc. It is mainly used for various lifting, pulling, loading and unloading heavy objects, and the oil tank is inverted. Welding, such as the installation and movement of various large and medium-sized concrete, steel structures and mechanical equipment, is suitable for civil engineering and bridge construction of construction and installation companies, factories and mines, electric power, shipbuilding, automobile manufacturing, construction, highways, bridges, metallurgy, and mining , Mechanical equipment for infrastructure construction projects such as slope tunnels, shaft treatment and protection.

Parameter model

The tonnage of the wire rope electric hoist is 0.5T/1T/2T/3T/5T/10T/16T/20T, and its standard wire rope meters are 6M/9M/12M/18M/24M/30M. It is also divided into CD1 (single-speed type) and MD1 (two-speed type),
The following is the running speed of wire rope electric hoist:
0.5T-5T 10T 16T-20T
Single speed: 8M/MIN Single speed: 7M/MIN Single speed: 3.5M/MIN
Two-speed: 8M/MIN, 0.8M/MIN, two-speed: 7M/MIN, 0.7M/MIN, two-speed: 3.5M/MIN, 0.35M/MIN

Structural features

The components of wire rope electric hoist are: motor, transmission mechanism, reel and wire rope. The motor and the reel can be roughly divided into four types based on the different positions of each other.
(1) The electric hoist whose motor axis is perpendicular to the axis of the drum adopts worm gear transmission, which is large in width, heavy in structure, low in mechanical efficiency, and difficult to process. No manufacturer produces products of this type of structure anymore.

(2) The electric hoist with the motor axis parallel to the drum axis has the advantage of small height and length. Its disadvantages are large width, grouping, and complicated manufacturing and assembly. The track turning radius is large.
(3) The electric hoist with the motor installed in the drum has the advantages of small length and compact structure. Its main disadvantages are poor heat dissipation conditions of the motor, poor grouping, inconvenient inspection, installation, and maintenance of the motor, and complicated power supply devices.
(4) The electric hoist with the motor mounted on the outside of 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 is large.
Components

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

1. Reducer 2. Reel device 3. Lifting 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 body 13. Seal 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. Vent plug
The roles and functions of each part are as follows:
Reducer: It adopts a three-stage fixed-axis helical gear transmission mechanism. The gears and gear shafts are made of heat-treated alloy steel. The box body and the 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 is equipped with a fire limiter for upper and lower stroke protection.
Steel wire rope: It adopts heavy-duty steel wire rope, which guarantees durability. Cone motor: The lifting motor adopts a larger power torque conical rotor to brake the asynchronous motor, no need to add a brake.
Button switch: Hand-operated, light and handy, divided into two ways: rope operation and cordless remote control.
Daily maintenance

Wire rope electric hoist
In daily inspection, monthly inspection, and annual inspection, all those that do not meet the requirements shall be repaired, adjusted or replaced immediately. Maintenance should meet the following requirements:
1. The material and performance of the replacement parts should be the same as the original parts during maintenance;
2. When structural parts need to be welded and repaired, the materials, welding rods and welding quality used should all meet the quality standards of the original structural parts;
3. When the electric hoist is in working condition, maintenance and maintenance are not allowed.
