Liebherr is a global leader in construction machinery. It has raised the bar again with the Liebherr LR1250 crawler crane. This new model belongs to the 250-tonne class. It combines groundbreaking self-sufficiency with intelligent control. It also features a robust undercarriage system. Together, these deliver unmatched performance and efficiency for demanding job sites.
Core Performance
Based on Liebherr’s official data and leading industry equipment databases, the LR 1250 presents compelling figures:
Maximum Lifting Capacity: 250 tonnes (approximately 275 US tons).
Hoisting Height: 148 meters when configured with a main boom and luffing jib, enabling work on high-rise construction and large-scale industrial installations.
Maximum Radius: 97 meters, offering extensive reach for complex lifts.
Boom System: Features a reinforced main boom with a standard length range of 20 to 117 meters (approx. 66 to 384 ft). It can be combined with a fixed jib (up to 32m/105ft) or a luffing jib (up to 95m/312ft) for exceptional versatility.
Power Unit: Powered by the efficient and reliable Liebherr D 936 A7 SCR Tier 4 Final/Stage V-compliant diesel engine.
Technical Highlights: Intelligence, Speed, and Independence
Revolutionary Self-Assembly System:
A standout feature is its sophisticated jack-up and self-assembly system, which allows for rapid setup without the need for an assist crane. This innovation significantly reduces mobilization time and cost, enhancing project readiness.
Intelligent Crane Control:
The LR 1250 is equipped with Liebherr’s advanced CAN-BUS electronic control system. This ensures extremely precise load handling and integrates multiple redundant safety systems, providing operators with confidence and control, even in visually restricted conditions.
The LR 1250 Undercarriage System
- Track Shoes (Pads/Plates): Manufactured from high-strength, alloy steel castings and subjected to specialized heat treatment (such as quenching and tempering). Available in various widths to optimize ground pressure (as low as approximately 1.0 kg/cm²), ensuring superior stability on soft or uneven terrain.
- Lower Rollers (Bogie Wheels) & Upper Rollers (Carrier Rollers): Designed with sealed and lubricated lifetime bearings to minimize maintenance and built to endure constant high-impact loads, thereby extending service intervals and durability.
- Sprockets & Idlers: Precision-machined and surface-hardened to ensure perfect meshing with the track chain links, delivering efficient power transmission and reduced wear.
Market Position and Applications
The Liebherr LR1250, with its blend of quick setup, powerful lift capacities, and cost-effective operation, is ideally suited for a wide range of applications. These include wind farm construction, oil & gas projects, bridge building, major industrial plant maintenance, and urban infrastructure development. It effectively fills the market need for a highly capable and versatile crane between larger and smaller models.
