Therefore, for the manufactures, what kind of lifting equipment is qualified inspection? Today, Weihua crane will introduce to you.
1.statistic test
The purpose of the static load test is to verify the structural load carrying capacity of the crane and its components. The static load test of each hoisting mechanism shall be carried out separately. Before the main hook is subjected to the static load test, the empty trolley should be parked in the middle of the span to set the reference point.
2.Dynamic test
The purpose of the dynamic load test is to verify the function of the crane's various mechanisms and brakes. The dynamic load test of each mechanism of the crane should be carried out separately, and then the joint action experiment should be carried out. At the same time, the two mechanisms are activated, but the main and auxiliary hooks cannot be started at the same time.
3.no-load test
After turning the various mechanisms by hand, the motor of each mechanism is started, and each mechanism should be able to operate normally. The limit switches can work reliably. The trolley drive wheel is in full contact on the track, and the crane and trolley run along the entire length of the track without gnawing rail.
4.visual inspection
Visually check that the specifications and status of all important parts meet the requirements.
