Electric wire rope hoist load test?
1, the trial run of the wire rope electric hoist
Newly installed or installed after dismantling the electric hoist, should first empty commissioning several times. But not pre-installed, avoid power-commissioning.
2, electric wire rope hoist overload test
Before normal use, a static load test should be carried out to 125% of the rated load is raised off the ground about 100 mm for 10 minutes, and checks whether it is normal.
3, electric wire rope hoist dynamic load test
Dynamic load test is based on the weight of the load rating for repeatedly lift and move around test after test to check the mechanical transmission parts, electrical parts and connected parts is normal.
4, the absolute prohibition of electric wire rope hoist operating environment
Use absolute prohibition does not allow the environment, and exceed the rated load and hourly rated closing times (120 times).
5, wire rope electric hoist installation, commissioning and maintenance
Installation, commissioning and maintenance must strictly check limit device is flexible and reliable, when hook up to the upper limit position, the hook shell to roll the shell of the distance must be greater than 50mm (10t, 16t, 20t must be greater than 120 mm). When the hook down to the lower limit position, should ensure the the reel wire rope safety circle, the the effective security ring must be more than 2 laps.
