Liebherr unveils 150 tonne cellular crane with 66 metre telescopic growth

With a most lifting capability of 150 tonnes and a 66 metre telescopic growth, it’s also an efficient addition to Liebherr’s crane vary beneath the 180 tonne LTM 1160-5.2

The ten % longer telescopic growth in comparison with its predecessor will hoist on common 15 % larger hundreds with each most and half ballast. And with this in thoughts, the Liebherr engineers have produced a minor miracle – the brand new crane has the identical low gross weight as its predecessor. With an axle load of twelve tonnes, the crane can carry 9 tonnes of ballast on public roads.

After the LTM 1120-4.1 in March, Liebherr has now unveiled the second new growth in its all-terrain crane vary this yr – the LTM 1150-5.3. Christoph Kleiner, gross sales director, says, “It has the longest growth on this crane class at 66 metres and may compete with crane fashions within the 200 tonne lifting capability class. It delivers excellent lifting capacities when totally raised and at giant radii. And it’s instantly prepared to be used as soon as it reaches the location. It is because the brand new 150 tonne crane carries 9 tonnes of a ballast with a gross weight of 60 tonnes. Which means it may possibly full numerous jobs with out requiring further ballast transport automobiles. That saves money and time, and makes the crane much more precious to crane contractors.”

In comparison with its predecessor, the telescopic growth on the brand new LTM 1150-5.3 is six metres longer. On the identical size of 60 metres, the brand new 5-axle crane can hoist 12 tonnes when totally raised – 1.5 tonnes greater than its predecessor. When totally prolonged to 66 metres, the brand new crane has a lifting capability of over 9 tonnes. That makes it excellent for erecting tower cranes and radio masts.

Lattice extensions permits the brand new 150-tonne crane to attain hook heights of as much as 92 metres and radii of as much as 72 metres. For this, one 7 metre lattice part as growth extension and a ten.8 to 19 metre double folding jib are used. The latter may be adjusted hydraulically between 0° and 40°. A 2.9 metre erection jib and a runner, which may be swung to the facet, spherical off the tools checklist. Significantly economical – the lattice jibs are suitable for a lot of crane fashions within the 100 to 180 tonne class throughout the Liebherr portfolio.

The time-tested six-cylinder Liebherr diesel engine within the undercarriage gives all of the drive energy the LTM 1150-5.3 wants. It develops 400 kW / 544 bhp and a torque of a 2516 Nm. The engine satisfies the brand new stage V emissions directive and can be configured to adjust to the rules which apply in international locations outdoors of Europe, for instance Tier 4 for the USA or stage IIIA for low regulated international locations. 

The ZF-TraXon gearbox is used to switch the ability to the crane’s axles. ECOdrive is especially economical – the extra eco mode delivers enhanced drive properties which save gas and scale back each noise and CO2 emissions. As well as, Hillstart Assist makes beginning on gradients simpler. 

Liebherr has continued its single-engine technique on this crane with a mechanical drive unit for the superstructure. The load discount created by the elimination of the superstructure engine from the earlier mannequin is used to ship an extended growth and extra lifting capability. 

Consistent with the newest developments from the Liebherr cellular crane sequence, the brand new 150 tonne crane additionally options ECOmode for crane operations to cut back gas consumption and emissions of each noise and CO2. Firstly, the whole pump drive may be disconnected robotically when the engine is idling after which reconnected by the clever controller in a matter of seconds when it’s required. And secondly, the crane controller robotically calculates the right engine velocity for the working velocity chosen utilizing the management lever to keep away from unnecessarily excessive engine speeds. 

Hook blocks must be heavy to make sure that the hoisting winch spools reliably. Nevertheless, they need to be as gentle as attainable for being transported on the crane and for top internet hundreds throughout hoists. Liebherr has designed a very new vary of hook blocks to fulfill these contradictory necessities – weight plates are connected to either side of the hook block to vary the load of the block in order that it’s excellent for the present scenario. Christoph Kleiner explains: “Our engineers have produced a easy, however sensible design because it signifies that operators can react much more flexibly to each job.” 

For instance, a 3-roller hook block, which beforehand has weighed 700 kg on this crane class, now solely weighs 500 kg, however may be upgraded to 700 kg shortly and simply when obligatory. The brand new system is obtainable for 1 to 7-roller hook blocks. These can be utilized on cranes with each 19 mm and 21 mm ropes. The weights may be interchanged to make sure easy dealing with.
