New 880-USt Mobile Crane Combines Roadability with Lattice-Boom Capacities

Dec. 19, 2023 – Liebherr’s new LG 1800-1.0 combines the strong lifting capacities of a lattice-boom crane with the mobility of a rubber-tired chassis. 

Scheduled to roll out in the first half of 2024, this new crane is the big brother of Liebherr’s LG 1750 lattice-boom mobile crane. 

The new LG 1800-1.0 lifts up to 880 U.S. tons. 

That’s 30 tons more than the LG 1750’s 850-USt maximum capacity. 

Also, the LG 1800-1.0 travels on nine axles. The LG 1750 has eight. 

The extra axle on the new LG 1800-1.0 helps reduce per-axle loadings for easier roadability. 

The new LG 1800-1.0 lattice-boom mobile crane lifts just as much as its counterpart, the LR 1800-1.0 lattice-boom crawler crane. 

And, like other Liebherr cranes, the LG 1800-1.0 comes with state-of-the-art technology, such as V-Frame, VarioTray, ZF Traxon Torque transmission, ECOdrive, and WindSpeed load charts.  

Flexible Driving is Suitable for All Markets 

One highlight of the new 9-axle vehicle is its unique chassis. 

The LG 1800’s axle arrangement works in all markets worldwide. 

The new crane has one more axle than its predecessor, and the axles on the new LG 1800-1.0 are the same standard axles used on Liebherr’s popular LTM mobile cranes. 

Equipped with all four of its lifting beams, the 198,416-lb. chassis can travel on public roads with per-axle loads of just 22,046 lbs. 

Traveling with only two of the support beams reduces the chassis’ total weight to 154,324 lbs., and with all four supports removed, the chassis travels at about 110,231 lbs. (12,248 lbs. per axle). 

In contrast to its predecessor, the LG 1800-1.0 has support beams that do not telescope. 

The new non-telescoping beams are more stable, lighter, and easier to attach and detach, thanks to a quick-coupling system. 

The crane’s 42’8” x 42’8” support-beam footprint lets the LG 1800-1.0 lift heavy capacities with a derrick system and raise long boom lengths even without a derrick. 

Ideal for Wind Work 

The chassis’ relatively narrow 9’10” width makes it economical to move both on roads and on construction sites, while its powerful engine and drive train let it climb grades of up to 25%. 

That power and mobility are particularly beneficial on wind farms, where the relatively narrow chassis can travel between turbines more easily than a wider crawler crane. 

The more-mobile, rubber-tired LG 1800-1.0 can use the familiar boom systems of the LR 1800-1.0 lattice-boom crawler crane. 

The main boom can be up to 590’ long. 

The maximum combination of main boom plus luffing jib is 354’+334’, which gives a maximum hook height of 682’. 

Optimized wind-power boom systems let the crane work with 570’ of boom and 59’ of lattice fixed jib to reach hub heights of 590’. 

Capacity charts based on permissible wind speeds of up to 30 mph (13.4 m/s) offer more flexibility and safety in gusty operating conditions. 

Modified Slewing Platform 

The equipment of the tire-mounted LG 1800-1.0 is compatible with that of the crawler-mounted LR 1800-1.0. 

All their accessories, from the boom’s head section to the lattice type fixed jibs and whip line, are identical, and their boom systems have the same designations. 

Also, their 22,046-lb. (10-tonne) counterweight plates can also be used on other Liebherr crawler cranes – saving cost and possibly reducing transport distances. 

The only difference between the new upperworks of the LG 1800-1.0 mobile crane and the LR 1800-1.0 crawler crane is a modified slewing platform that allows longer boom systems to be raised without a derrick. 

Powerful lifting capacity, long boom-and-jib combination, a narrow travel width, and low axle loads should make the new LG 1800-1.0 popular in a variety of applications, including wind-tower work.
