The daily maintenance of crane is very important, early detection of failure and timely solution, to extend the service life of crane parts have a certain role.

1, the structural part is the frame support of the truck crane, cleaning, cleaning and maintenance of its surface, showing a beautiful and strong appearance is a very important inspection item, when you wipe, you can observe whether the appearance of deformation, wear, weld whether there is a crack, find the problem timely repair, the coefficient of dangerous accidents to the minimum.
2. The connection of the structural parts depends on several key hinge shafts, which is very important for lubrication, related to the flexible operation between the structural parts, prevent clogging, and play an important role in the disassembly and assembly of the hinge shafts in the future. If the shaft is rusted inside and bitten by the structural parts, it will have the consequence that it cannot be disassembled, so the hinge point shaft must be lubricated regularly, so that the lubricant is injected with a certain pressure until the lubricating oil spills from the two joints. After refueling, each close point should do a few complete actions, and then a little more oil.
3. Surfaces that produce relative motion between the various structural components also need lubrication. For example, a surface that generates relative friction between an active arm and a telescopic arm. If the lubricant is insufficient, the frictional resistance will increase, creating abnormal noise, shaking and trembling, resulting in the telescopic arm surface not being able to maintain the same straight line. The wear of the slider between the telescopic arms must be checked regularly. If the lubricant is insufficient, the friction will increase, causing the telescopic arm to open or loosen in a disorderly manner, resulting in the telescopic arm cannot be kept in the same straight line. Before applying the new oil, the original old butter must be scraped off with a rubber knife, and a coat of butter must be applied to the outer surface of the extended arm with a brush.
