How should a truck-mounted crane be maintained and serviced properly

The maintenance work of truck-mounted cranes involves meticulous inspection and upkeep in multiple aspects. The following are several key inspection points: First, conduct a routine comprehensive inspection to ensure that there is no loosening or oil leakage at all pipeline connections and fixed seals. At the same time, carefully check whether all the fasteners are firm, especially the crossbeam, chassis frame, slewing bearing and the connecting parts between the crossbeam and the column. In addition, the inner and outer ring bolts on the slewing bearing should be tightened in accordance with the specified tightening torque to ensure safety and stability. Secondly, check whether the power take-off control switch and pressure gauge of the truck-mounted crane are working properly to ensure smooth and accurate operation. At the same time, it is also necessary to check the sufficiency of hydraulic oil and lubricating oil to ensure the normal operation of the hydraulic system. In addition, the usage condition of the steel wire rope and its accessories is also an important inspection item, including the firmness of the rope clamps and the wear and rust of the steel wire rope. Once any abnormal conditions such as kinks, creases, severe wear, rust, excessive wire breakage or significant reduction in diameter are found in the steel wire rope, a new one should be replaced in a timely manner. Finally, it is also necessary to check whether there is any damage or deformation on the surface of each component of the truck-mounted crane, as well as the tightness of the synchronous steel wire rope. While keeping the truck-mounted crane in operation, it is also necessary to listen to the sound of the hydraulic system and monitor the temperature to ensure its normal operation.
