First, 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 reel shell must be greater than 50mm
Second, in use, it is absolutely forbidden to use it in an unacceptable environment, or when it exceeds the rated load and the rated number of closings per hour.
Third, the electric hoist that is newly installed or installed after disassembly and inspection should first be tested for several times in an empty car.
But before the installation is complete, do not try to turn on the power.
Fourth, perform a static load test before normal use and check whether it is normal.
Fifth, when adjusting the braking slip of the electric hoist, the braking slip should be guaranteed under the rated load. Sixth, after the work is completed, the main switch of the power supply must be opened to block the power supply. Seventh, it is not allowed to press two flashlight door buttons that make the electric hoist move in opposite directions at the same time. (10t, 16t, 20t must be greater than 120mm). When the hook is lowered to the lower limit position, the safety loop of the steel wire rope on the drum shall be ensured, and the effective safety loop must be more than 2 loops.
