LTR 1060 extends the range of telescopic crawler cranes
Liebherr is extending the range of telescopic crawler cranes with the new LTR 1060. With its 40 m telescopic boom, the new 60-tonner goes beyond the telescopic crawler cranes currently available in this size class both with regard to load capacity as well as its boom length. In addition to this, the telescopic boom can be extended with a double swing-away jib from 9.5 m to 16 m in length, which enables heights under hook of up to 54.5 m, and reaches of up to 48 metres can be achieved. The boom technology and the crane control system of the LTR 1060, which has been optimised accordingly, now offer the possibility of telescoping heavy loads, something which is basically not possible with lattice mast booms.
The new LTR 1060 combines the advantages of a telescopic crane with those of a crawler crane. The crawler travel gear provides excellent off-road capability, with good manoeuvrability at the same time. As well as this, the full load can be moved with the crane. The advantages of the telescopic crane are short set-up times, easier transport, and the variability of the boom system. The telescopic boom is fully automatic, and can be extended rapidly to the desired length, and because the crawler crane does not need to be supported it can be moved around swiftly on the site and is ready to go into action again immediately.
The structural design of the new 60-tonne telescopic crawler crane allows for particularly economical transport. Complete with slew superstructure and central ballast, the LTR 1060 weighs only 61 tonnes. Axle loads, with three-axle tractor units and five-axle low-loaders, remain less than 12 tonnes. During transport the crawler travel gear is telescoped in to 3.0 metres, and, thanks to the low crane height of 3.15 metres, economical standard low-loaders can be used.
Thanks to its structure and design, the new LTR 1060 crawler crane is ideally suited for the assembly of prefabricated components. With an erection jib 2.5 metres long and the second hoist gear, assembly operations can be carried out in two-hook operation. The load taken off the low-loader with the erection jib is transferred to the second hook on the telescopic boom, which means that prefabricated components can then be swung into the correct position and moved to the assembly location with the crawler travel gear.
