What are the usage specifications of wire rope electric hoist?

The advantage of wire rope electric hoist is that its length and size are small, and the motor is installed in the drum.

The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the drum axis adopts worm gear transmission device. Its disadvantages are: large length and width, bulky structure, low mechanical efficiency, difficult processing, etc. The hydraulic system is double controlled, and the overflow regulating valve and magnetic contact pressure gauge can control the pressure. The electrical control department adopts low-voltage control, which increases the dominance of the system. No manufacturer produces products with this structure.

Structure and features: the machine adopts the electromechanical integration design. By changing different molds, different specifications of steel wire ropes can be pressed, which is simple and safe to control. Its main disadvantages are poor heat dissipation premise of the motor, poor grouping, convenient inspection, installation and maintenance of the motor, and complex power supply device. The electric hoist with the electric motor axis parallel to the drum axis has the advantage of small height and length. Its disadvantages are large width, poor grouping, and complex manufacturing and assembly.

Classification and description of wire rope electric hoist the components of wire rope electric hoist include: motor, transmission mechanism, drum and sprocket. It can be roughly divided into four types based on the different positions of motor and drum. The pressed steel wire rope has large tension, beautiful appearance and fast speed. It only takes a few minutes to crimp a set of steel wire rope, which greatly reduces the labor intensity and improves the work efficiency.

The electric hoist with the motor installed outside the drum has the advantages of good grouping, high generalization, easy to change the lifting height, and convenient device inspection.

The use of electric hoist can be said to be very extensive, but there may be few people who can correctly use the advantages of Taiyuan electric hoist price electric hoist to operate. I suggest you to learn more about the characteristics of electric hoist and this knowledge, so that it is better to use electric hoist.

1. For the electric hoist newly installed or installed after disassembly and inspection, the empty vehicle test run shall be carried out for several times at first. However, before the installation is completed, do not power on for trial run.

2. Before normal use, a static load test should be carried out at 125% of the rated load and about 100 mm above the ground for 10 minutes to check whether it is normal.

3. The dynamic load test is to conduct repeated lifting and moving tests to the left and right with the rated load weight. After the test, check whether the mechanical transmission part, electrical part and connecting part are normal and reliable.

4. During use, it is forbidden to use it in an impermissible environment and when it exceeds the rated load and the rated closing times per hour (120 times).

5. During installation, commissioning and maintenance, it is necessary to strictly check whether the limit device is flexible and reliable. When the hook rises to the upper limit position, the distance between the hook shell and the drum shell must be greater than 50mm (10t, 16t, 20t must be greater than 120mm). When the hook drops to the lower limit position, ensure that the steel wire rope circle on the drum, and the effective circle must be more than 2 circles.

6. It is not allowed to press two manual switch buttons at the same time to make the electric hoist move in the opposite direction.

7. After the work is completed, the main gate of the power supply must be opened and the power supply must be cut off.

8. The electric hoist should be operated by a specially assigned person, and the operator should fully grasp the operating procedures, and it is strictly forbidden to pull and hoist askew.

9. During use, special personnel must regularly check the electric hoist, take measures in time if any fault is found, and carefully record it.

10. When adjusting the braking sliding amount of electric hoist, ensure that the braking sliding amount s ≤ v/100 under rated load (V is the stable lifting distance within one minute under load).

11. Scrapping standard of steel wire rope: the inspection and scrapping standard of steel wire rope shall be implemented in accordance with cb/t5972-1986 "code of practice for inspection and scrapping of steel wire rope for crane".

12. The electric hoist must keep enough lubricating oil in use, and keep the lubricating oil clean, without impurities and dirt.

13. When oiling the steel wire rope, a hard brush or small wooden pieces should be used. It is strictly forbidden to oil the working steel wire rope directly by hand.

14. When the electric hoist is not working, it is not allowed to hang heavy objects in the air to prevent parts from deformation.

15. In the process of use, if a fault is found, the main power supply should be cut off immediately.

16. Pay special attention to the wearing parts during use.

17.10~20 ton hoist may have automatic power failure after long-term continuous operation, which belongs to the overheating protection function of the motor. At this time, it can be lowered. After a period of time, it can continue to work after the motor cools down.
