Liebherr will be unveiling its new LTM 1120-4.1 at the Conexpo in Las Vegas using the slogan ?There?s nothing more on 4!? It is the most powerful 4-axle all-terrain crane ever built, according to the company. The new 135 US ton (120 t) machine breaks into a performance class which has previously been the sole preserve of 5-axle cranes. As far as boom length is concerned, it is on a par with 240 US-ton (200 t) class cranes as its 217 ft (66 m) telescopic boom is the longest ever to be installed on a 4-axle mobile crane. Liebherr will start deliveries of the new LTM 1120-4.1 in autumn 2020.

The new 135 US ton (120 t) crane has added 18 per cent to this value at the same length. What is more, the LTM 1120-4.1 can extend its telescopic boom to up to 217 ft (66 m), an additional 10 per cent. This means it reaches the same level of many 240 US ton (200 t) mobile cranes on the market.

The new LTM 1120-4.1 delivers outstanding lifting capacity values, particularly with the boom fully raised. Its lifting capacity of 19,800 lb (9 t) on the 217 ft (66 m) telescopic boom makes it ideal for erecting tower cranes and radio masts. Lattice extensions enable the new 135 US ton (120 t) crane to achieve hook heights of up to 308 ft (94 m) and radii of up to 210 ft (64 m). For this a 23 ft (7 m) lattice boom extension is installed as well as a 35 to 62 ft (10.8 to 19 m) double folding jib, which, as an option, can also be hydraulically adjusted between 0? and 40?. A 6.6-ft (2 m) erection jib and a runner, which can be swung to the side, round off the equipment list.

The new LTM 1120-4.1 can tackle jobs which normally would require a 5-axle crane, eliminating all the logistics work needed for the larger model. Because a 4-axle crane delivers benefits in terms of licensing and route permits, it can tackle jobs faster and with greater flexibility. The design of a 4-axle crane also enables it to work where there is insufficient space for larger cranes. On constricted sites, in particular, Liebherr?s VarioBallast? and VarioBase? innovations deliver enhanced performance, flexibility and safety for this new crane model.
