Proper use of climbing frame electric hoist can not only extend the service life of the product, but also greatly improve the work efficiency, and can also effectively reduce the probability of dangerous accidents. Today I will discuss with you how to use the climbing frame electric hoist correctly: 1. The newly installed electric hoist or the electric hoist installed after disassembly and inspection should be tested with empty cars several times. Before the installation is complete, it is strictly prohibited to turn on the power. 2. Before use, a static load test of 125% of the rated load, about 100 mm from the ground, and 10 minutes of static load test should be carried out, and check whether it is normal. 3. The dynamic load test is based on the rated load weight for repeated lift and left and right movement tests. After the test, check whether the mechanical transmission part, electrical part and connection part are normal and reliable. 4. When the work is completed, the main switch of the power switch must be opened to cut off the power. 5. It should be specially operated by the electric hoist of the climbing frame. The operator should fully grasp the safety operation rules, and it is strictly prohibited to pull the crane diagonally. 6. In use, the electric hoist must be regularly inspected by special personnel, and if a fault is found, measures should be taken in time and carefully recorded. 7. In the process of use, it is prohibited to use in the environment that is not allowed, and in the case of exceeding the rated load and the rated closing times per hour (120 times). 8. During installation, commissioning and maintenance, you must 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 wire rope safety ring on the drum should be ensured, and the effective safety ring must be more than 2 circles.
