1. The electric hoist installed after the new installation or after being dismantled shall first be put into trial operation several times. However, before the installation is completed, avoid switching on electricity;
2, before normal use should be carried out with a rated load of 125%, lifting from the ground about 100 mm, 10 minutes of static load test, check whether it is normal;
3, dynamic load test is the rated load weight, for repeated lifting and left and right movement test, after the test to check the mechanical transmission part, electrical parts and connecting parts are normal and reliable;
4. It is not allowed to simultaneously press two flashlight door buttons that make the electric hoist move in the opposite direction;
5, electric hoist should be manipulated by a person, the operator should fully grasp the safety operation procedures, non-pulling oblique crane; installation and commissioning and maintenance, must strictly check whether the limit device is flexible and reliable, when the hook rose to the upper limit position, hang The distance from the hook shell to the drum shell must be greater than 50mm (10t, 16t, 20t must be greater than 120mm).
6. When the hook is lowered to the lower limit position, it is necessary to ensure that the wire rope safety loop on the reel, the effective safety circle must be more than 2 turns;
7. In use, it is absolutely forbidden to use in the environment where it is not allowed, and when the rated load and the number of rated closings per hour (120 times) are exceeded. The electric hoist must be inspected regularly by specialized personnel, and faults must be promptly taken and measures must be taken. After completion of work, the main gate of the power supply must be pulled open to cut off the power supply.
