Crawler Crane Lower Rollers Usages as below:
- Track rollers directly support the entire weight of crawler crane, and the pressure is distributed to the ground through the crawler tracks, reduce the pressure on the ground and avoid the crane from sinking, especially on the soft ground.
- The coordination of bottom rollers and track plates can limit the lateral offset of the crawler tracks and reduce the friction loss of bottom plates and chassis structure.
- The rolling characteristicsof lower rollers make crawler tracks smoother when moving, reduce sliding friction with the ground, and save power consumption.
- With the uniform distribution of multiple sets of track rollers, the crane can move smoothly on uneven ground, such as gravel, mud…

LIEBHERR Crane Roller Body Half Daily Maintenance:
- Wear monitoring
The thickness of rollers rim is measured every 250 working hours, and the wear exceeds 10% of the original size and needs to be replaced.
Check the bottom rollers surface for abnormal damage such as cracking and peeling.
- Tightness checks
Observe the oil seal for signs of grease leakage or muddy water infiltration.
Clean up the gravel and sediment accumulated in the grooves of the roller body half to prevent the seals from being scratched.
- Tension adjustment
Keep track shoes sag 20-40mm (the measuring point is between the two top rollers), and over-tightening accelerates roller bushings wear.
- Crawler floor plates maintenance
Replace over-worn bottom plates in time to avoid increase bottom rollers impact loads due to poor meshing.
