Electric gourd referred to as electric hoist is a light small lifting equipment. Electric hoist has the characteristics of small size, light, simple, easy to use, used in industrial and mining enterprises, warehouse terminals and other places. The lifting weight is generally 0.1-80 tons, the heating height is 3 to 30 meters. So, what is the operating procedures for electric hoist safety use maintenance technology?
1. Electric gourd installed after the new installation or after the dismantling, the air trial operation should be carried out several times. However, before the installation is installed, the power is avoided.
2, 125% of the rated load should be performed before normal use, from about 100 mm, 10 minutes, 10 minutes, and check whether it is normal.
3, the dynamic load test is based on rated load, repeated lifting and left and right moving tests. After testing, the mechanical transmission portion, the electrical portion, and the connection portion are normal.
4. In use, it is absolutely prohibited from being used in an unauthorized environment, and more than the rated load and the number of rating per hour (120 times) are used.
5. When installing debugging and maintenance, it must be strictly checked whether the limit device is flexible and reliable. When the hook rises to the upper limit position, the hook housing to the reel housing must be greater than 50 mm. When the hook is reduced to the lower limit position, the wire rope safety ring on the reel should be guaranteed, and the effective safety ring must be above 2 laps.
6. Do not allow the two flashlights that make the electric hoist in the opposite direction at the same time.
7. After the work is completed, the power supply must be opened and the power is turned off.
8. Electric gourd should be manipulated by special people, and the manipulator should fully grasp the safety operation procedures, which are strictly prohibited.
9. In use, the specialist must be checked by the electric hoist regularly, and the fault takes a timely measure and records carefully.
10. When adjusting the amount of electric hoist brakes, the balance should be guaranteed, and the braking decline s ≤ V / 100 (V is a stable lifting distance within one minute of the load).
11. Electric gourd must be maintained enough lubricating oil and keep the lubricant clean and should not contain impurities and dirt.
12. Water brush or wooden small sheets should be used when the wire rope is oil, which is strictly forbidden to use the hand to the wire rope that is working.
13. When electric hoist does not work, it is not allowed to be hovered in the air to prevent parts from being permanently deformed.
14. During use, if the fault is found, the main power should be cut immediately.
15. Special attention should be paid to the case of the loss.
After the 16th, 10-20 tons of gourds have been running for a long time, there may be automatic power-off phenomena, which belongs to the overheating protection function of the motor. At this time, it can continue to work after a while.
