Product Description

Liebherr has extended its portfolio of all-terrain cranes with another 300-tonne model. With its 90 metres 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.

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 fewer than 60 tonnes and axle loads of under ten tonnes. Liebherr can also deliver a self-assembly solution that enables the telescopic sections to be removed without the need for an auxiliary crane.

Wide range of innovations

Wind speed load charts

Load charts available for various wind speeds are available for the LTM  1300-6.3. They deliver enhanced safety and longer operating times for crane work in windy conditions.  Load charts for cranes are generally only valid for gust wind speeds of up to 9 m/s. To ensure that work can continue safely in even higher wind speeds, Liebherr has calculated the load charts for additional maximum wind speeds and programmed them in the crane control system. For the LTM 1300-6.3, for example, it is 11.2 m/s, or even 13.4 m/s when using lattice equipment. In pure telescope mode, the tables even allow for a speed of 15.6 m/s. If the wind speed measured on the crane’s boom during a job exceeds the set chart wind speed, the crane operator can simply switch to a load chart with a higher maximum wind speed which will often allow the job to be continued.

VarioBase®Plus

The rear supports have a double-stage design and achieve a support width of 9.4 metres, 2 metres wider than the front supports. This increases the capacity over the rear supports even more. The single-stage front outriggers have a lower weight, which also benefits the boom length.

ECOdrive

An eight-cylinder Liebherr diesel engine in the undercarriage which develops 455 kW / 619  bhp and torque of 3,068 Nm provides the LTM 1300-6.3 with all the power it needs. The power is transferred to the crane axles by the 12-speed ZF TraXon torque gearbox. A torque converter ensures perfect manoeuvring. The additional ECOdrive mode delivers enhanced drive properties which both save fuel and reduce noise.

Single-engine concept with ECOmode

Liebherr has continued its single-engine strategy on the new  LTM 1300-6.3 with a mechanical power unit for the superstructure. The weight reduction created by removing the superstructure engine has been used to deliver a longer boom and more ballast with an axle load of 12 tonnes. ECOmode in crane operation helps to reduce fuel consumption and noise emissions. The complete pump drive is disconnected automatically when the engine is idling and then reconnected by the intelligent controller in a matter of seconds when required.

VarioBallast®

The new LTM 1300-6.3 can be operated with two different ballast radii: 4.94 m or 5.94 m.  The ballast radius can be reduced quickly and easily by one metre using standard mechanically adjusted ballasting cylinders. This solution is one of the main benefits of the new 300-tonne model when used in constricted conditions. The large ballast radius achieves maximum capacity. In fact, with its VarioBallast feature, the new crane can be operated with 8 tonnes less ballast compared to the LTM 1300-6.2 without any significant reduction of its lifting capacity. That reduces both transport logistics and CO2 emissions.

Auto-Ballast

A single touch of a button is all that is required to secure the ballast to 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 tonnes 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 full set-up crane on constricted sites.

New options

The optional central lubrication system for the kingpin 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.
