Crane and heavy lift equipment manufacture Liebherr has launched its LG 1800-1.0 lattice boom crawler crane. The unit has been designed with the wind energy industry in mind, with an axle load of 10 tonnes a 3 m-wide chassis.
The successor the LG 1750 lattice boom crane, the new crawler combines the advantages of a mobile crane with the load capacity of a lattice boom crane. The LG 1800-1.0 can lift up to 800 tonnes and features state-of-the-art crane technology such as V-Frame, VarioTray, ZF Traxon Torque transmission with ECOdrive and WindSpeed load charts.
Liebherr said the nine-axle chassis, thanks to a special arrangement, is suitable for all markets worldwide. With an axle load of 10 tonnes, the crane can drive on public roads with all four supports and a total weight of 90 tonnes. Alternatively, transport is possible with only two supports and a total weight of 70 tonnes, as well as completely without supports at around 50 tonnes.
In contrast to its predecessor, the eight-axle LG 1750, the folding beams on the new 800-tonne crane are not telescopic. The required support base of 13 m x 13 m is sufficient for the LG 1800-1.0 to achieve enormous load capacities with the derrick system and good erectable lengths without. The advantage of this, according to Liebherr, is that fixed supports are more stable and save weight. They are also easier to attach and detach thanks to a quick coupling system. The new crane uses the standard axles from the LTM crane product portfolio.
With a chassis width of just 3 metres, the new crane can be moved extremely economically both on the road and on construction sites and can even cope with gradients of up to 25 percent, added Liebherr.
The boom system is identical to that used on the crane’s tracked counterpart, the LR 1800-1.0. The main boom can be configured up to 180 m long, on its own. It can be used with a luffing jib, in configurations up to 108 m of main boom and 102 m of luffing jib, for a maximum hook height of 208 m. The LG 1800-1.0 is expected to launch in the first half of 2024.
