After the hoist gantry crane no-load test conditions are normal, the load test is allowed. The load test is divided into static and dynamic two types. The static load test is carried out first, and then the dynamic load test is carried out.
Inspection content of the hoist gantry crane load test.
(1) The quality of bolt connection and welding at each connection of the crane metal structure is mainly the quality of the main end beam connection.
(2) The strength and rigidity of mechanical equipment, metal structures and spreaders, and the strength of crane rails.
(3) The brake should act flexibly and work reliably.
(4) The crane reducer is no noise.
(5) The lubrication of the lubricated parts is good, and the temperature rise of the bearing does not exceed the regulations.
(6) The components of each mechanism should be stable and free of vibration. If there is any defect, the defect should be repaired before inspection.
