  Cantilever craneis a commonly used lifting machinery, before the first use of its trial run, test its performance is good, so today's theme is the first Test run cantilever crane to pay attention to the problem.

First, no-load experiment: Apart from the launch of the various agencies click, so that the rotation arm according to the time and inverse rotating 2-3 weeks, the operation must not have abnormal phenomenon, chain hoist or electric hoist trolley horizontal operation between two to three times should be smooth, do not run, wheel tread and beam track with outstanding. Hook up and down three to five times should be no abnormal sound, not card chain electric hoist chain or electric hoist wire rope.

Second, static test: The operation of the car and the rotation mechanism to stop the state, so that the chain electric hoist in the lower end of the spiral arm of the limit azimuth, to 1.25 times times the extra load for the test crane, the load increased from the ground 100mm, suspended for 10 minutes after unloading, the agencies should not be abnormal

Third, the load experiment: In the static load experiment outstanding case, takes the extra load to carry on the lifting experiment, from the ground 200mm stays 10 minutes, the successive hoisting three times, each organization normal, the braking decline is not more than 80mm. After the experiment, the parts can be put into use without any abnormality.

Above is the cantilever crane in the first run of the time need to pay attention to the problem, want to know more detailed consultation, welcome to lock our official website.
