Industrial overhead crane static test
time:Oct 19,2016
The Industrial overhead crane are all required dynamic and static load test and other tests after installation, overhaul, transformation and so on, the test results reach the relevant safety technical requirements, the industrial overhead crane can be put into use.
During Industrial overhead crane static load test, first, the crane lifts the weight of 1.5 times of rated lifting weight, hanging it to the height of 100-200mm from the ground, then adds the lifting weight until reaches the 1.25 times of rated lifting capacity, keep suspension for not less than 10 minutes. Unloading and check the Industrial overhead crane situation, repeat 3 times, check whether the crane has permanent deformation or not.
The main data are as follows: The curvature of main girder is not less than 0.7s / 1000 and the curvature of cantilever is not less than 0.7L / 350. Check the Industrial overhead crane, no cracks, the connection part is not loose.
The whole static load test process is as follows: parking the trolley at the middle of main girder, the lifting heavy objects of 1.25 times of the rated load, suspend for not less than 10 minutes, repeat 3 times, after each unloading need to check And record the data, finally based on the data to evaluate the performance of Industrial overhead crane.
