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 90 metre telescopic boom with an axle load of just 12 tonnes. The new 300 tonne 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 300-tonne model. With its 90 metre 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 78-metre 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 12 tonnes. 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 60 tonnes and axle loads of under ten tonnes. 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.
Record-breaking boom
The record length of 90 metres 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 12 tonnes, 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 – 11.5 to 20 metre double folding jib, two 7 metre lattice sections to extend the telescopic boom, a 39 metre powerful fixed jib and a 43 metre hydraulically adjustable fixed jib. That enables the new 300 tonne crane to reach hoist heights of up to 120 metres. Particularly economical – various lattice sections are also compatible with other models in the Liebherr portfolio.
The turntable. That takes the strain off the crane operator as the automatic ballasting process is simple, fast and convenient. In addition, safety is also enhanced, particularly for routine procedures.
The maximum ballast on the LTM 1300-6.3 is 88 tonnes. The 10 tonne suspended ballast blocks on the right and left are compatible with the LTM 1230-5.1 and LTM 1250-5.1 crane models. That makes them another economical solution for operators with these cranes in their fleets. There is also the fact that the individual ballast slabs have been modified in terms of their weight and dimensions to make them suitable for economical transport and fast, easy set up on site. All the ballast can be placed on the crane with just five hoists. The basic ballast of 42 tonnes has a width of just 3 metres, which means that it fits within the overall width of the vehicle. This makes it significantly easier to move the fully set-up crane on constricted sites.
New options – the optional central lubrication system for the king pin bearings on the chassis is a new feature. It delivers grease to 24 lube points on the 6-axle crane automatically. Another highlight is that a total of six LED rear lights are available to order, which illuminate the working area perfectly with bright light for manoeuvring on the site.
