Liebherr will be showing its new 300 tonne (360 US-tons) mobile crane on a six-axle chassis at the Conexpo Con/Agg 2014. The LTM 1300-6.2 was unveiled at the Bauma 2013 and replaces the 250-tonne (300 US-tons) LTM 1250-6.1. Its 78 m (256 ft) telescopic boom means that this new six-axle mobile crane offers an additional 6 m (20 ft) in length over its predecessor. In addition its load capacity has been increased dramatically. The new LTM 1300-6.2 from Liebherr is the most powerful mobile crane in the 300 tonne (360 US-tons) class available on the market.

At the 2014 construction machinery exhibition in Bern (Switzerland), Liebherr presents its 300 tonne mobile crane on a six-axle chassis, which has been reveiled at the 2013 Bauma. The LTM 1300-6.2 features a 78 m telescopic boom, which means an additional 6 m in length over its predecessor, the 250-tonne LTM 1250-6.1. In addition, its load capacity has been increased considerably. The new LTM 1300-6.2 from Liebherr is the most powerful 300-tonner available on the mobile crane market.

The 12.5 m - 21.5 m double folding jib can be extended by two additional 7 m sections to a total of 35.5 m. The folding jib can be erected at an angle of 0°, 20° or 40° or as an option can be adjusted hydraulically between 0° and 40° whilst fully loaded. The 5.5 m foot section of the folding jib can be used as a heavyweight erection jib and provides a considerable load capacity of 58 t.

An eight-cylinder Liebherr diesel engine which develops 450 kW / 612 bhp at 1,900 rpm and torque of 2,856 Nm at 1,500 rpm provides the LTM 1300-6.2 with all the power it needs. The power is transferred to the crane axles via the 12-speed ZF-TC-Tronic gearbox. A torque converter has been installed for starting and accurate manoeuvring. The intarder, a zero wear hydrodynamic brake integrated in the gearbox acts as a retarder. In addition a Telma eddy current brake is available as an option. Like almost all LTM mobile crane models, the LTM 1300-6.2 is fitted with pneumatic disc brakes which Liebherr was the first manufacturer to introduce for mobile cranes some years ago.

The four rear axles on the six-axle chassis of the new 300-tonner have active electro-hydraulic steering depending on the vehicle speed. This increases the manoeuvrability of the vehicle and drastically reduces tyre wear. At crab steering speed all six axles are steered which means that there is no need to raise any axles. Five steering programmes can be selected conveniently at the touch of a button.
