Long, powerful telescopic boom
Compared to its predecessor, the telescopic boom on the new LTM 1150-5.3 is six metres longer. At the same length of 60 metres, the new 5-axle crane can hoist 12 tonnes when fully raised – 1.5 tonnes more than its predecessor. When fully extended to 66 metres, the new crane has a lifting capacity of over 9 tonnes. That makes it suitable for erecting tower cranes and radio masts.
Lattice extensions enable the new 150-tonne crane to achieve hook heights of up to 92 metres and radii of up to 72 metres. For this, one 7 metre lattice section as boom extension and a 10.8 to 19 metre double folding jib is used. The latter can be adjusted hydraulically between 0° and 40°. A 2.9 metre erection jib and a runner, which can be swung to the side, round off the equipment list. The lattice jibs are compatible with many crane models in the 100 to 180-tonne class within the Liebherr portfolio.
Economical drive technology with ECOdrive and ECOmode
The time-tested six-cylinder Liebherr diesel engine in the undercarriage provides all the drive power the LTM 1150-5.3 needs. It develops 400 kW / 544 bhp and a torque of 2516 Nm. The engine satisfies the new Stage V emissions directive and can also be configured to comply with the regulations which apply in countries outside of Europe, for example, Tier 4 for the USA or stage IIIA for low regulated countries.
The ZF-TraXon gearbox is used to transfer the power to the crane’s axles. The additional eco mode delivers enhanced drive properties which save fuel and reduce both noise and CO2 emissions. In addition, Hillstart Aid makes starting on gradients easier.
Liebherr has continued its single-engine strategy on this crane with a mechanical drive unit for the superstructure. The weight reduction created by the elimination of the superstructure engine from the previous model is used to deliver a longer boom and more lifting capacity.
In keeping with the latest developments from the Liebherr mobile crane series, the new 150-tonne crane also features ECOmode for crane operations to reduce fuel consumption and emissions of both noise and CO2. Firstly, the complete pump drive can be disconnected automatically when the engine is idling and then reconnected by the intelligent controller in a matter of seconds when it is required. And secondly, the crane controller automatically calculates the perfect engine speed for the working speed selected using the control lever to avoid unnecessarily high engine speeds.
