The main regular maintenance work of double beam crane

Nowadays, with rapid socio-economic development, double beam cranes are appearing more and more frequently in our field of vision. However, double beam cranes belong to material handling machinery and perform intermittent movements, where the corresponding mechanisms for picking up, transporting, unloading, and other actions alternate in a working cycle. The unit using double beam lifting machinery should regularly inspect and maintain the double beam lifting machinery in use, detect any abnormal situations at any time, and handle them in a timely manner to ensure the operation of the double beam lifting machinery.

Daily inspection: a routine maintenance project carried out by the driver, mainly including cleaning and hygiene, lubrication of transmission parts, adjustment and fastening work. By running the sensitivity test device, monitor for any abnormal sounds during operation.

Weekly inspection: jointly conducted by maintenance workers and drivers, in addition to daily inspection items, the main content is visual inspection, checking the status of hooks, retrieval devices, wire ropes, etc., the sensitivity and performance of brakes, clutches, emergency alarm devices, and observing whether there are abnormal noises and overheating phenomena in transmission components through operation.

Monthly inspection: mainly conducts status checks on the power system, lifting mechanism, slewing mechanism, operating mechanism, and hydraulic system of lifting machinery, replaces worn, deformed, cracked, and corroded components, and inspects 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 to understand and master the technical status of the entire crane, and identify the source of abnormal phenomena.

Annual inspection: Conduct technical parameter testing and performance testing on lifting machinery. Through testing instruments, inspect the wear of moving parts of lifting machinery and various working mechanisms, weld seams of metal structures, and conduct testing and flaw detection. Arrange plans for major repairs, renovations, and updates.

The above are some reminders from Shandong Longmen Crane manufacturer to customers about the main regular maintenance work of double beam cranes. Only with regular inspections and maintenance can the machine extend its lifespan and improve efficiency.
