LIEBHERR LR1000 Crawler Cranes Advantages:
- Superior lifting capacity
Extra-large load: LR11000 crane can lift up to 1000 tons, suitable for ultra-heavy lifting tasks (such as wind turbines, bridge components, etc.).
Wide working range: the maximum length of the main boom is up to 168 meters, and it can be extended to 240 meters in combination with the luffing jib, covering complex working conditions. - Efficient and flexible power system
Diesel-electric dual drive: suitable for areas with strict environmental protection requirements.
Fast assembly: The modular design reduces on-site assembly time to 3-5 days (7-10 days for similar models). - Strong environmental adaptability
Ground pressure optimization: Wide track pads (optional 2m width) to reduce the ground specific pressure: Extra-wide track shoes (8.5 m × 2 m) as standard, with a ground specific pressure of < 80kPa, can work safely on soft ground.
Wind resistance: The maximum allowable wind speed is up to 14m/s (about level 7 wind), and it is equipped with an automatic wind speed alarm system.

Our LIEBHERR Crane Track Rollers Advantages:
- Material is 42CrMo as LIEBHERR Original drawing requirements, to adapt to the heavy load LR11000 crane.
- Copper bushings and best Floating seals make rollers body half long working life and perfect performance under any working condition.
- Heat treatment, whole Quenching & Tempering improve the toughness of the core of bottom rollers, and avoid brittle fracture; high-frequency quenching of surface enhance wear resistance.
- CNC machining accuracy, the tolerance of key dimensions (such as track shoes’ hole diameter and pitch) is controlled within ±0.05mm, and the roughness Ra ≤ 3.2μm.
LIEBHERR Crane Bottom Rollers Daily Maintenance:
- Wear monitoring
Measure flange thickness every 250 working hours. Replace if wear exceeds 10% of original size.
Check track rollers surface for abnormal damage such as cracking and spalling.
- Check for tightness
Observe the oil seal for signs of grease leakage or muddy water.
Cleaning roller body half groove accumulation of gravel, sediment, to prevent the seal scratch.
- Alignment calibration
Regularly check the deviation between the center line of lower rollers and crawler track frame (≤0.5mm/m) to prevent eccentric wear.
Systematic maintenance can extend the service life of support rollers by 30%-50% while reducing the risk of unplanned downtime by more than 20%.
