Before the electric round chain hoist is in normal use, it should be noted that it must be carried out at 125% of rated load, so that it will rise from the ground about 100 millimeters for 10 minutes of static load test, then Should pay attention to check is not normal. The electric chain hoist should also be dynamic load test, and after the test is to pay attention to check the mechanical transmission part, electrical parts and connection parts.
Electric round chain hoists in the use of the time, the absolute prohibition of the environment is not allowed, in fact, that is, in excess of the rated load and the rated closing times per hour (120 times) under the circumstances of the use. In its installation and commissioning and maintenance, it is necessary to pay attention to strictly check its limit device is not flexible and reliable, when the hook rose to the limit position, the hook shell to the reel housing Distance is to be aware of must be greater than 50mm (10t, 16t, 20t must be greater than 120mm).
Then, when the electric chain hoist down to the lower limit of the time, it should be to pay attention to ensure that the rope safety rope reel, and in terms of its effective safety zone, it is necessary to pay attention to more than two laps before they can. Moreover, we actually need to pay attention to the use of electric chain hoist, in fact, that is not allowed to press at the same time two electric chain hoist in the opposite direction of a series of flashlight button.
In addition, we actually have to pay attention to the electric chain hoist after the work is done must be the total gate to open the power, the next to say, in fact, it should be to cut off its power .
Finally, in terms of electric chain hoist, in fact, it should be that attention should be paid by someone to manipulate, and in terms of the operator should be to fully grasp its safe operating procedures, but also pay attention not to tilt the crane hanging. The electric chain hoist in the use of certain time by specialized personnel to regularly check the device.
