30-Second Takeaway
Liebherr has raised the bar for mobile lattice boom cranes with the LG 1800-1.0, delivering up to 800 tonnes of lifting capacity on a wheeled chassis. Combining the mobility of a mobile crane with the power of a crawler, the nine-axle LG 1800-1.0 matches the performance of the LR 1800-1.0 while remaining road-legal worldwide. Designed with the wind industry in mind, the crane supports hub heights up to 180 meters, advanced WindSpeed load charts, and full equipment compatibility with Liebherr’s LR crawler crane platform.
A New Benchmark for Lattice Boom Cranes on Wheels
Like its predecessor, the LG 1800-1.0 merges the advantages of a mobile crane with the load capacity traditionally reserved for lattice boom crawler cranes. However, where the LG 1750 was once among the most powerful cranes of its kind, the LG 1800-1.0 surpasses it entirely, establishing itself as one of the most powerful lattice boom cranes on wheels worldwide.
With a maximum lifting capacity of 800 tonnes, the LG 1800-1.0 matches the performance of its crawler counterpart, the Liebherr LR 1800-1.0, while offering significantly greater mobility and transport efficiency.
Engineered for Global Mobility and Wind Power Projects
A defining feature of the LG 1800-1.0 is its nine-axle mobile chassis, engineered to meet global road regulations. With an axle load of just 10 tonnes, the crane can travel on public roads worldwide without special restrictions.
Its 3.0-meter chassis width and ability to handle gradients of up to 25% make it particularly well suited for wind farm applications, where cranes must move efficiently between turbine locations.
Transport configurations include:
90 tonnes total weight with four supports
70 tonnes with two supports
Approximately 50 tonnes without supports
This flexibility allows the crane to operate across diverse markets and terrains with minimal logistical complexity.
Advanced Technology Built In
The LG 1800-1.0 incorporates Liebherr’s latest crane technologies, including:
V-Frame® for improved load distribution
VarioTray® for flexible ballast configurations
ZF TraXon Torque transmission with ECOdrive for efficient travel
WindSpeed load charts allowing safe operation at wind speeds up to 13.4 m/s
A redesigned slewing platform enables the erection of longer boom systems without a derrick, setting the LG 1800-1.0 apart from the LR 1800-1.0 in terms of setup flexibility.
Boom Systems and Equipment Compatibility
One of the most strategic advantages of the LG 1800-1.0 is its full compatibility with LR 1800-1.0 equipment. All accessories from boom sections and head pieces to lattice-type fixed jibs and whip lines share identical designations and interfaces.
Key configurations include:
Main boom up to 180 meters
Main boom + luffing jib with hook heights up to 208 meters
Optimized wind power setup: 174-meter boom + 18-meter fixed jib, supporting hub heights of 180 meters
The crane also uses 10-tonne counterweight plates that are interchangeable with other Liebherr crawler cranes, reducing fleet investment and transport distances.
Stability, Simplicity, and Faster Setup
Unlike the eight-axle LG 1750, the LG 1800-1.0 uses fixed folding supports rather than telescopic beams. The required 13 × 13-meter support base delivers high load capacities with or without the derrick system.
The fixed supports:
Improve overall stability
Reduce crane weight
Simplify attachment and removal via a quick-coupling system
Standard axles shared with the Liebherr LTM product line further enhance serviceability and parts commonality.
Why It Matters
The LG 1800-1.0 represents a major evolution in crane design, particularly for wind energy, infrastructure, and large industrial projects. By delivering crawler-level lifting power on a road-legal mobile platform, Liebherr has created a crane that reduces transport time, lowers logistical costs, and expands jobsite flexibility without compromising performance.
