Harbor cranes occupy an important position in the port development. The slewing bearing is an important component connecting the slewing part and the fixed part of the harbor crane. The smooth operation of the slewing bearing has a significant impact on the operation of the entire harbor crane.
At the same time, the harbor crane slewing bearing is complicated to bear the vertical force, the horizontal force and the overturning moment. Therefore, it is particularly important to select a suitable harbor crane slewing bearing.
Harbor crane slewing bearings-Maintain
1. The slewing bearing should be greased regularly. According to different types of slewing bearings, the specific grease filling time is as follows: the ball type is filled with grease every 100 hours of operation; the roller type is filled with grease every 50 hours of operation.
2. The sundries on the surface of the slewing ring should be removed frequently during use, and the sealing strip of the slewing ring should be checked for aging, cracking, damage or separation. If one of these conditions occurs, the sealing strip should be replaced in time to prevent debris from entering the raceway and the loss of grease.
3. Pay close attention to the operation of the slewing ring during use. If you find that the noise, impact, or power suddenly increases, you should stop the machine immediately for inspection until all the faults are eliminated, and disassemble and inspect if necessary.
