1.The slewing bearing must be carefully installed and removed.2.The transportation and storage should be placed horizontally, and the storage must be placed in a dry room.3.Lifting should be done with lifting ring screws in a horizontal way, and do not collide, especially in the radial direction.4. The outer surface of the slewing bearing is coa...
Abnormal Noise(1) The slight abnormal noise when the new product is idling will generally disappear after dozens of turns. If it does not disappear, it may be caused by slight deformation of the slewing bearing during transportation.(2) After the assembly, there is abnormal noise in the trial operation. It should be checked whether the installat...
ShakeAfter the slewing bearing is loaded, its clearance is about 3-5 times that of the factory inspection (three-point inspection method), and it can continue to be used within this range.(1) The mounting bolts are loose, causing shaking during work. Immediately check all inner and outer ring mounting bolts and tighten as required.(2) The rigidi...
Broken toothReasons:(1) The backlash of the large and small gears is improperly adjusted during installation.(2) Failure to adjust the meshing clearance with the pinion at the maximum position of the tooth jump as required, resulting in a stuck and broken tooth during operation.(3) The axes of the large and small gears are not parallel or the mo...
1. Immersion methodFor small bearings, it can be soaked in anti-rust grease to reduce the chance of rusting.2, brushing methodFor some larger slewing bearings, the soaking method cannot be used, and it can be brushed. When brushing, pay attention to evenly smear on the surface of the slewing bearing, so as not to cause accumulation and leakage.3...

First of all, pay attention to the danger of being dragged into the rotary pinion, crushing and shearing. During inspection and maintenance, make sure that repair workers are not in the danger zone between the main boom, the loading vehicle and the roller.Next, check the slewing bearing bolts1. The crane needs to regularly check the bolts on the...
