The correct use of climbing frame electric hoist can ensure safety and the service life of climbing frame electric hoist. 1. Electric hoist newly installed or installed after disassembly and inspection should first be run for several times with empty vehicle. However, before the installation is complete, avoid power-on trial transfer. 2. Before normal use, a static load test of 125% of the rated load, lifting about 100 mm from the ground, and 10 minutes of static load 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. In use, it is absolutely forbidden to use in an environment that is not allowed, and when the rated load and the rated closing times per hour (120 times) are exceeded. 5. 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. 6. It is not allowed to press two flashlight door buttons that move the electric hoist in the opposite direction at the same time. 7. After the work is completed, the main gate of the power supply must be opened to cut off the power supply. 8. It should be operated by a special person, and the operator should fully grasp the safety operation regulations, and it is strictly prohibited to pull the crane diagonally. 9. In use, the electric hoist must be regularly inspected by special personnel, and measures shall be taken in time if a fault is found and carefully recorded. 10. When adjusting the brake hoisting amount of the electric hoist, it should be ensured that under the rated load, the brake sliding amount S≤V/100 (V is the distance that the load will rise steadily within one minute).
