Use and maintenance of stage electric hoist
1. Newly installed or dismantled electric hoists should first undergo several empty car test runs. But before the installation is completed, do not turn on the power for trial operation.
Before normal use, a static load test should be conducted at 125% of the rated load, lifting about 100 meters above the ground, for 10 minutes, and checked for normal operation.
3. Dynamic load test is a repeated lifting and left-right movement test conducted based on the rated load weight. After the test, the mechanical transmission part, electrical part, and connection part are checked for normal and reliable operation.
4. In use, it is absolutely prohibited to use it in an environment that is not allowed, or in situations where it exceeds the rated load and the rated closing frequency per hour (120 times).
5. During installation, debugging, and maintenance, it is necessary to strictly check whether the limit device is flexible and reliable. When the hook is raised 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 is lowered to the lower limit position, the safety ring of the steel wire rope on the drum should be ensured, and the effective safety must be at least 2 countries.
6. It is not allowed to press two manual switch buttons simultaneously to move the electric hoist in opposite directions.
After completing the work, the main switch of the power supply must be opened and the power supply must be cut off.
8. The electric hoist should be operated by a dedicated person, and the operator should fully learn and grasp the safety operating procedures. It is strictly prohibited to pull or lift it at an angle.
9. During use, specialized personnel must regularly inspect the electric hoist, take timely measures if faults are found, and carefully record them
When adjusting the braking sliding amount of the electric hoist, it should be ensured that under the rated load, the braking sliding amount S is ≤ V/100 (V is the stable lifting distance within one minute under the load).
