Wharf cranes and port cranes are important mechanical equipment used in port terminals to move goods, which can improve economic exchanges in various regions, promote economic development, and have a great role in promoting the wharf economy. Qualification inspection of quay cranes is very important, if it does not meet the requirements of use, it will cause safety failures.
You can first roughly observe whether the parts of each part meet the specifications for use and whether they are in good condition. After turning each mechanism by hand without jamming, when the motor of each mechanism is turned on, each mechanism should be able to operate normally, each limit switch can work reliably, the driving wheel of the trolley is in full contact on the track, and the large and small vehicles run along the full length of the track. The gnawing and three-legged phenomenon.
It is necessary to carry out static load test and dynamic load test on the crane to check the load-bearing capacity of the crane and the functions of various mechanisms and brakes. The static load test inspects the structural load-bearing capacity of each part of the crane, and the static load test of each lifting mechanism should be carried out separately. The dynamic load test is to verify the functions of the various mechanisms and brakes of the crane.
The crane can only be inspected and used after all parts of the crane are qualified to ensure that the safety devices are in place, operate the crane correctly, and reduce the occurrence of failures.
Cranes are large-scale machinery and equipment with many applications. Cranes can be seen in ports, wharfs, and urban construction. The crane needs to be overhauled after a period of time. This is to check whether there are bad accessories, replace some aging equipment, and improve the performance of the crane.
If it is determined to be overhauled, the first thing to ensure is personal safety. When adjusting the gap of the adjusting brake of the lifting accessories, replacing the worn clutch or the friction plate, the seat of the driving room can be easily adjusted up and down, and it can also deal with the safety problems that simply lead to the injury of the driving and repairing personnel and the malfunction of the machine.
Some parts that need to be replaced should be replaced in time, and the places that need to be lubricated should be lubricated in time. Pay attention to the precautions for lubrication. Some parts that need to be adjusted should be adjusted well to facilitate the operator to better operate the equipment. If the machine parts are damaged, serious oil leakage, water leakage, air leakage and electricity leakage, etc., when it is necessary to disassemble the main components for repair, it is good to have professional maintenance personnel to repair it. The overhaul of the crane is to improve the performance of the crane and extend the service life.
