New 300 tonne Liebherr with 90 metre boom
19 January 2022
Liebherr claims a world record for its latest model of wheeled mobile telescopic crane.
The six axle LTM 1300-6.3 is claimed as the first crane with a 90 metre telescopic boom and an axle load of 12 tonnes.
Its maximum hoisting height is given as 120 metres. Typical target applications are erecting tower cranes and tall aerials, plus wind turbine maintenance.
While it can run at 12 tonnes per axle its boom and the outriggers are designed for easy removal where reduced axle loads are required. Its tele-separation feature allows removal of individual telescopic sections from the eight section boom. Using this feature means a gross weight of less than 60 tonnes and axle loads below ten tonnes can be achieved.
A self-assembly version of the tele-separation system requires no auxiliary crane and can also be used with other models, for example, LTM 1650-8.1 and LTM 1450-8.1.
It has one 455 kW engine and the Ecomode, Ecodrive, VarioBase Plus, VarioBallast and Auto-Ballast features. Drive is via a 12-speed ZF TraXon automated manual gearbox with torque converter.
Lattice jibs available include 11.5 to 20 metre double folding jib, two 7 metre lattice sections to extend the telescopic boom, a 39 metre fixed jib and a 43 metre hydraulically adjustable jib. Some of the sections can be used on other cranes.
Maximum ballast is 88 tonnes. The 10 tonne suspended ballast blocks each side can also be used on LTM 1230-5.1 and LTM 1250-5.1 models. Basic ballast is 42 tonnes and 3 metres wide, as per the width of the crane.
A new option is a central lubrication system for 24 points on the chassis.
The preceding model LTM 1300-6.2 with 78 metre boom will remain in the range.
