First of all, the lubrication form, the lubrication form of the crane is divided into two types: disperse lubrication and centralized lubrication. The dispersing lubricating oil has the advantages of simple structure, reliable lubrication, convenient maintenance and low cost. The disadvantages are: lubrication point dispersion and oil filling occupation time comparison Long; concentrated lubrication can be divided into manual lubrication and motorized dry oil lubrication, in the operation must be done step by step according to the instructions. For the newly installed lubrication system, it is necessary to test the oil distribution joints connected to the lubrication points first, until the lubricating oil flows out at each joint, and check that there is no residual dirt in the grease and then connect with the lubrication point. For the farthest point, it is important to note that the lubrication system must not leak.
Secondly, the arrangement of lubrication points, the lubrication point distribution of the truck crane is roughly: the thrust bearing under the hook pulley shaft and the hook nut; the fixed pulley shaft ends; the steel wire rope; each reducer; each gear coupling; Bearing housing; motor bearing; hinge point on brake; piston part of long stroke brake electromagnet; anti-roller; cable reel; guide roller; gear, screw and hinge point on rail clamp; Device, etc.
Finally, please pay attention to the precautions for the lubrication of the truck crane: the lubricating materials must be kept clean, the grease of different brand numbers can not be mixed; always check the sealing of the lubrication system, regularly add lubricating grease; ensure that the lubricating oil road is not squeezed When pressing the pipe, the pipe end and the joint must be protected to avoid bumping or mixing impurities. When reinstalling, the dirt at the joint should be carefully removed to ensure the oil circuit is clean; the joints are not lubricated. Where grease is used, regular use of thin oil pots should be placed in each of the rotating gaps to reduce wear and prevent corrosion of the parts.
The lubrication of the truck-mounted crane must be in place. Only in this way can the service life of the truck crane be effectively extended.
