With the development of society, the quality, volume and lifting height of materials that need to be hoisted are also getting larger and larger. Rubber-tyred cranes are increasingly showing their superiority, so the demand for them is becoming increasingly strong. So how should we check whether the tire-type crane is qualified?
1. When a tire-type crane passes the inspection, it must first pay attention to visual inspection and visually inspect whether the specifications and status of all important components meet the requirements; after that, it should also conduct a no-load test. At this time, after the motors of each mechanism are started, the motors of each mechanism should be turned by hand to ensure normal operation.
2. For tire-type cranes, static load tests should also be conducted. In fact, the purpose of the test is to test the structural bearing capacity of the crane and its components; the static load test of each lifting mechanism should be carried out separately. Before carrying out the static load test on the main hook, the air switch should be stopped in the middle of the span and the measuring point should be determined.
3. Pay attention to the dynamic load test. The purpose of the dynamic load test is to verify the functions of the crane and brakes. The dynamic load test of each mechanism on the crane equipment should be carried out separately, and then the joint action test should be carried out. Both mechanisms should be activated at the same time, but the main hook and auxiliary hook must not be activated at the same time.
