Liebherr Unveils Record Breaking 90m Telescopic Boom on New LTM 1300-6.3
Unveiling the LTM 1300-6.3 also sees Liebherr set a new world record – never before has a mobile crane been able to carry a 90m telescopic boom with an axle load of just 12t. The new 300t model will add to the portfolio of Liebherr 6-axle cranes. It is a versatile, economical fast-erecting crane with a peerless telescopic boom length. The latest Liebherr innovations are included to enable the LTM 1300-6.3 to deliver economical, safe, powerful crane operation – ECOmode, ECOdrive, VarioBase®Plus, VarioBallast®, Auto-Ballast, single-engine concept and wind speed load charts. The LTM 1300-6.2 will remain in the portfolio as the entry point model into the class of luffing jib cranes.
Liebherr has extended its portfolio of all-terrain cranes with another 300t model. With its 90m telescopic boom, the LTM 1300-6.3 sets new standards in the 6-axle class and goes well beyond what the current cranes on the market have to offer. It is designed to be used as a fast-erecting crane with a high capacity at great hoist heights with a raised boom. That makes it ideal for erecting tower cranes and antennae as well as for wind turbine maintenance work. The LTM 1300-6.2 with 78m telescopic boom, offered by Liebherr in parallel, is the economical entry into the luffing jib class and in this configuration already offers unrivalled load capacities for a 6-axle mobile crane.
Liebherr has made it possible to drive the LTM 1300-6.3 with different axle loads and gross weights, to ensure that it can be driven economically all over the world. Components such as the telescopic boom and outriggers can be installed and removed quickly and easily to achieve axle loads of less than 12t. One particularly interesting feature in this respect is tele-separation, which enables individual telescopic sections to be removed particularly quickly. This makes it straightforward to set up the crane for the road with a gross weight of less than 60t and axle loads of under 10t. Liebherr can also deliver a self-assembly solution which enables the telescopic sections to be removed without the need for an auxiliary crane. This is compatible with other models such as the LTM 1650-8.1 and the LTM 1450-8.1. The flexibility and economy of the crane is increased enormously as a result.
The record length of 90m is achieved by the new LTM 1300-6.3 using an 8-section telescopic boom – the pivot section plus seven telescopic sections. That is one section more than similar cranes in this class. To ensure that the complete boom as well as all the outriggers plus the hook block can be carried on public roads with an axle load of 12t, Liebherr has optimised the entire steel construction of the crane for lightweight construction.
Although the LTM 1300-6.3 is not designed for use as a luffing jib crane, it has a wide range of lattice jibs available – 11.5m to 20m double folding jib, two 7m lattice sections to extend the telescopic boom, a 39m powerful fixed jib and a 43m hydraulically adjustable fixed jib. That enables the new 300t crane to reach hoist heights of up to 120m. Particularly economical – various lattice sections are also compatible with other models in the Liebherr portfolio.
