How to operate the loop chain electric gourd
Chain electric hoist operation procedure: The electric gourd that is installed after the new installation or overhaul should be carried out several times. However, before the installation is complete, avoid the electric test. It should be carried out at 125% of the rated load before normal use, up to about 100mm from the ground, 10 minutes of static load test, and check if it is normal. 3. The dynamic load test on the rated load weight, for lifting and moving test repeatedly, after test to check the mechanical transmission parts, electrical parts and the connection is normal and reliable. In use, it is absolutely prohibited to be used in conditions that are not allowed, as well as above the rated load and the rated number of relocks per hour (120 times). 5. Installation and maintenance, must strictly check whether the spacing device is flexible and reliable, when the hook rose to the limit position, hook enclosure to the drum shell of distance must be greater than 50 mm (10 t, 16 t, 20 t must be greater than 120 mm). When the hook is lowered to the lower limit, it should be ensured that the wire rope safety ring on the drum, and the effective safety ring must be above two circles.
5. Had wire rope electric hoist when debugging must strictly check the limit switch is flexible and reliable, when the hook rose to the limit position, hook enclosure to the drum shell of distance must be greater than 50 mm (10 t, 16 t, 20 t must be greater than 120 mm). When the hook is lowered to the lower limit, it should be ensured that the wire rope safety ring on the drum, and the effective safety ring must be above two circles. 6. Chain electric hoist when debugging, hook up or down to the limit position, must be noticed when buffer spring start braking debug whether limit switch, avoid improper debugging limit switch failure caused by the header.
Ong the professional production of various kinds of electric hoist crane As electric hoist and European crane manufacturers distributors, Leon crane in the theory and practice for many years, summed up the electric hoist products operation shall abide by the following principles: 1. The new installation or after overhaul of electric hoist, first of all should be empty test run several times. Before the installation is finished, avoid the electric test. Normal use should be carried out at the rated load 125%, rise from the ground about 100mm, 10 minutes of static load test, check is normal. 3. The dynamic load test on the rated load weight, for lifting and moving test repeatedly, after test to check the mechanical transmission parts, electrical parts and the connection is normal and reliable. In use, it is absolutely prohibited to be used in an environment where it is not allowed, and for exceeding the rated load and the rated number of times per hour (120 times).
