Crawler Dozers
Liebherr Crawler Dozers: Hydrostatic Power – Superior Dozing Performance – Exceptional Durability
HANDLING CAPACITY & APPLICATIONS
Land Leveling
Automatically stabilizes the blade to achieve precise surface grading, slope formation, and accurate 2D finish grading without the need for additional laser or GPS systems, ensuring superior grading quality and maximum productivity.
Mining of ore, limestone, and bauxite
Designed for exceptional durability and operational flexibility across a wide range of mining applications. The heavy-duty undercarriage and reinforced structural design ensure reliable, continuous operation over multiple shifts in harsh terrain conditions.
Infrastructure, Dam & Road Construction
The ideal solution for infrastructure projects, highways, dams, and road construction, thanks to its precise leveling capabilities, powerful hydrostatic thrust, and superior durability.
KEY ADVANTAGES
Efficient mining productivity through advanced technologies
- Continuously variable hydrostatic drive with no gear shifting required
- Intelligent Operator Assist System (OAS) with optimized grading and automation functions optimize every working cycle for maximum productivity
High performance - Continuous Operation in Harsh Environments
- Designed for continuous 24/7 operation under maximum working loads
- Easily operates for up to 6,000 hours/year
Optimized Fuel consumption
- Eco mode optimizes fuel efficiency and minimizes CO₂ emissions during low-load applications
- Load-sensing hydraulic system supplies exactly the power required for each operating condition. Automatic idle control and engine shutdown
Maximized Lifetime
- The undercarriage is designed for a lifetime of up to 60,000 hours under continuous heavy-duty operation
- Core components are manufactured by Liebherr, ensuring maximized components lifetime
- An automatic central lubrication system continuously lubricates critical components during operation, significantly increases component lifetime compared with manual lubrication systems performed only during machine downtime
Remote Management - Operational and Diagnostics Support
- Remote monitoring of machine status, operation, and fuel consumption via the LiDAT management system
- Mobile monitoring application - My Assistant for Earthmoving
- Fault diagnosis and lookup tool - Myliebherr
