Liebherr LR1800

The Liebherr LR 1800 crawler crane is engineered for maximum lifting performance in large-scale construction, industrial, and infrastructure projects. With an impressive maximum load moment of 12,100 tm, the LR 1800 is capable of lifting up to 800 tons, depending on boom configuration and working radius.

Its main boom configurations range from 21 meters to 112 meters in light-duty setup and up to 126 meters in heavy-duty configuration, allowing flexible adaptation to various project requirements. For greater reach and lifting flexibility, the crane can be equipped with a luffing jib ranging from 35 to 91 meters. Additionally, the LR 1800 offers optional derrick systems with suspended ballast or ballast trailers carrying up to 450 tons of counterweight, improving stability and lifting performance at extended radii.

The crane is powered by a 12-cylinder DaimlerChrysler OM 444 LA turbo-diesel engine delivering 605 kW (823 hp) at 1900 rpm and peak torque of 3,260 Nm between 1,000 – 1,600 rpm. The drive system uses six axial piston variable displacement pumps in closed hydraulic circuits for precise control and smooth operation across all crane functions.

Hydraulic winches provide high lifting speeds up to 106 m/min with maximum rope tension of 206 kN on the main hoist, auxiliary hoists, and derrick functions. Slewing is driven by hydraulic motors through planetary gearboxes, providing smooth 360° rotation under load. The LR 1800’s crawler undercarriage includes hydraulically powered drives in each carrier for synchronized, independent, or counter-rotating travel with 1.5-meter wide pads (2.0 m optional) and centralized lubrication.

Operator comfort is enhanced with a spacious, steel-constructed cab that tilts rearward for improved upward visibility, featuring modern control instruments, electronic safety systems including load moment indicators, hoist limiters, and electronic inclinometers. Optional equipment includes air conditioning, quick connection systems for easier transport, and mechanical or hydraulic supports for assembly/disassembly.

Ballast configuration options include:

• 142 t central ballast (extendable by an additional 110 t)
• 238 t superstructure ballast (extendable by 76 t)
• Up to 450 t suspended ballast or ballast trailer systems

Designed for modular transport, efficient setup, and powerful lifting, the Liebherr LR 1800 stands as a top choice for large projects demanding both strength and versatility in the 800-ton crawler crane class.
