The slewing bearing of the truck-mounted crane transport vehicle is an important part of the truck-mounted crane's slewing mechanism, which drives the truck-mounted crane's boom to rotate and run, covering the entire working surface.

The basic working principle of the slewing ring is: the inner ring and the outer ring of the slewing ring are respectively installed with slewing brackets, and connected to the driving equipment. The pinion in the driving equipment meshes with the inner and outer teeth of the slewing ring to complete the supporting movement of the entire slewing mechanism.

Maintenance of the slewing bearing of the transporter of the truck-mounted crane

The bolts of the slewing bearing of the truck-mounted crane transport vehicle should be checked regularly for looseness. Check once after 100 working hours for the first time, check again after 300 working hours, and check every 500 working hours thereafter;

The tightening torque of the inner and outer ring bolts on the slewing bearing of the truck-mounted crane transport vehicle is 290N.m;

The slewing bearing of the truck-mounted crane transport vehicle should be regularly checked for the flexibility of the slewing. If noise or impact is found, it should be stopped immediately for inspection, troubleshooting, and dismantling when necessary;

The slewing bearing of the truck-mounted crane transport vehicle should be regularly checked for cracks or damage to the slewing ring gear, and whether the meshing tooth surface has bite, gnawing, tooth surface peeling, etc.;

The slewing bearing of the truck-mounted crane transport vehicle should be checked regularly for the integrity of the seal. If the seal is found to be damaged, it should be replaced in time, and if it is found to be falling off, it should be reset in time;

The slewing bearing of the truck-mounted crane transport vehicle should be buttered twice a week, and the slewing bearing of the turntable should be buttered once a week.

How to replace the slewing bearing of the truck-mounted crane transport vehicle

Lay the jib of the crane flat, unscrew all the bolts on the slewing bearing, and separate the slewing bearing from the base;

Install the new slewing bearing on the base, wipe the bolts clean, apply thread fastening glue, and then tighten them. The tightening torque of the inner and outer ring bolts on the slewing bearing is 290N.m;

Check the flexibility, noise, seal and ring gear status of the slewing ring. If there is no abnormality, it can be used normally.
