The electric chain hoist must be tested for no-load operation before use
Many customers think that a new electric chain hoist is not necessary for no-load test. The new electric hoist has the best performance. It will carry out a tensile tonnage test when it leaves the factory, and each performance test will only be passed after the test is qualified. After leaving the factory for sale, why do I need to conduct no-load test again after receiving the equipment?
Since the site where the manufacturer conducts the test is different from the site where the product is used by the manufacturer, the electric hoist that is newly installed or installed after disassembly and inspection should first be tested with no load. After several times, if there is no abnormality, the next step can be carried out, but a reminder is required The thing is, if the installation is not completed, do not try to turn on the power.
Before normal use, carry out a static load test of about 100 mm from the ground at 125% of the rated load for 10 minutes, and check whether it is normal. This is what we call an overload test. The dynamic load test is to perform repeated lifting and moving left and right tests with the rated load weight. After the test, check whether the mechanical transmission part, the electrical part and the connection part are normal and reliable.
Don't be careless about the no-load test, it must be tested before it can be put into use.
