Main regular maintenance work of double beam crane

Nowadays, with the rapid development of social economy, double girder cranes appear more and more frequently in our vision. However, the double beam crane belongs to the material handling machinery, which does intermittent movement, that is, in a working cycle, the corresponding mechanisms of picking, moving, unloading and other actions work alternately. The user unit of double beam lifting machinery should often check and maintain the double beam lifting machinery in use, and if there is any abnormal situation, it should be found at any time and handled in time, so as to ensure the operation of double beam lifting machinery.

Daily inspection: the driver is responsible for the routine maintenance items of the operation, mainly including cleaning, lubrication of transmission parts, adjustment and fastening. Test the sensitivity of the device by running, and monitor whether there is abnormal sound during operation.

Weekly inspection: it is jointly carried out by maintenance workers and drivers. In addition to daily inspection items, the main contents are appearance inspection, inspection of the use status of hooks, retrieval devices, wire ropes, etc., sensitivity and performance of brakes, clutches, emergency alarm devices, and observation of whether the transmission parts have abnormal noise and overheating through operation.

Monthly inspection: mainly inspect the status of the power system, lifting mechanism, slewing mechanism, operating mechanism and hydraulic system of the lifting machinery, replace the worn, deformed, cracked and corroded parts, and inspect the feeding device, controller, overload protection and protective device of the electrical control system. Observe and subjectively inspect the structure, support and transmission parts of the crane, understand and master the technical status of the whole crane, and check and determine the fault source of abnormal phenomena.

Annual inspection: carry out technical parameter detection and performance test for lifting machinery, and arrange overhaul, transformation and update plans for the wear of moving parts of lifting machinery and working mechanisms, welds of metal structures, testing and flaw detection through detection instruments.

The above are some reminders about the main regular maintenance work of the double beam crane given by Shandong gantry crane manufacturer to your customers. Only when regular inspection and maintenance are done well can the machine prolong its service life and improve efficiency.
