Precautions for the use of climbing frame electric hoist: 1. The newly installed climbing frame electric hoist installed or dismantled and inspected should first be run for several times with an empty vehicle, but before the completion of the installation of the climbing frame electric hoist, avoid turning on the electricity . 2. Before the normal use of the climbing frame electric hoist should be carried out at 125% of the rated load, lifted about 100 mm from the ground, 10 minutes of static load test, and check whether it is normal. 3. The dynamic load test of climbing frame electric hoist is based on the rated load weight, repeated up and down and left and right movement test, after the test, check the mechanical transmission part, electrical part and connection part are normal and reliable. 4. In use, it is absolutely forbidden to use it in an environment that is not allowed and when it exceeds the rated load and the rated closing times per hour (120 times). 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 simultaneously to make the climbing frame electric hoist move in the opposite direction. 7. After the work of climbing frame electric hoist is completed, the main brake of the power supply must be opened to cut off the power supply. 8. The electric hoist of the climbing frame should be operated by a special person. The operator should fully grasp the safety operation rules, and it is strictly forbidden to pull it diagonally. 9. In the use of climbing frame electric hoist, special personnel must regularly check the climbing frame electric hoist, take measures in time if a fault is found, and record it carefully. 10. When adjusting the brake sliding amount of climbing frame electric hoist, it should be ensured that under the rated load, the brake sliding amount S≤V/100 (V is the stable lifting distance of the load within one minute).
