The LTF 1035-3.1, which is erected on a 3-axle truck carrier, offers a maximum load capacity of 35t and a 30m telescopic boom. The LTF 1045-4.1, which has a 35m telescopic boom and a maximum load capacity of 45t, is designed to be erected on a 4-axle carrier. The two new cranes give Liebherr, it said, the opportunity to offer crane operators an economical alternative in the load capacity class between 30 and 50t.
As pure taxi cranes, they can be driven on public roads with all equipment and are thus ready for immediate use on the building site. Their axle loads are significantly lower than those of all-terrain (AT) cranes and this has a positive effect on their permit options.
Liebherr said that the design of a standard truck means that it consumes less fuel than a comparable AT. Moreover, it added, the new LTF 1035-3.1 and LTF 1045-4.1 feature a separate superstructure engine, the output of which is matched to the requirements of crane operation. As a consequence, operation of the crane superstructure also results in reduced fuel consumption. A Liebherr 4-cylinder diesel engine with an output of 145 kW/197 hp is used and satisfies the requirements of the latest exhaust emission regulations.
Depending on the crane configuration, load capacities have been increased by up to approximately 35% compared to Liebherr’s earlier models, the LTF 1030 and the LTF 1040. A 15m biparted fly-jib can be attached to the 30m telescopic boom of the LTF 1035-3.1. This is identical in design to the folding-fly jib of the Liebherr LTM 1030-2.1 mobile crane.
For Liebherr, compact dimensions were an important factor during the development of the new LTF cranes, as these models are required to manoeuvre and operate on confined building sites. With a support base width of only 6.2m and a ballast radius of just 3m, Liebherr believes the new LTF 1035-3.1 and LTF 1045-4.1 set the standard in the class for truck mounted cranes.
Both new LTF cranes are optionally available with remote radio control, which enables all the principle functions to be controlled outside of the crane cabin. This in turn allows the crane driver to affix the load in a single-person operation. A further advantage is the crane driver’s direct view of the load, which is particularly important during complex erecting tasks.
