The launch of two new towers is a highlight on the stand. Liebherr will be presenting the new, modular design of 150 EC B 8 Litronic flat top tower, available in a 6 or 8t version, as well as a new luffer, 357 HC-L, especially useful for high buildings.
It says the 150 EC B 8 is configuration-flexible, making it an economically attractive concept in crane leasing.
The flat top is available either in FR.tronic or Litronic versions; meaning operated by programmable logic control PLC or traditional contactor control. There is a choice between cabin and non-cabin operation.
The 8t version has a freestanding hook height of more than 52m, a maximum lifting capacity at the tip of 1700kg at 60m radius and a maximum load capacity of 8000kg.
It can be fitted to a 120 HC tower system, and optionally onto 185 HC and 256 HC tower systems.
Also launching at the show is Liebherr 357 HC-L 18/32 Litronic luffer. It has been developed as the successor to the 355 HC-L and is available in 12/24t and 18/32t versions. The 32,000kg version will be on the stand.
Liebherr explained one of the 357 HC-L’s features is a compact 6 x 6m cruciform base and uniquely narrow tower system. "The 355 IC standard tower system, unique in this crane class, is available as a climbing tower system for the 357 HC-L both for interior climbing and for climbing outside the building. A striking feature is the exceptionally compact 1.9 x 1.9m tower cross-section, meaning the 355 IC can also be climbed in narrow elevator shafts," it said. This is also the first exhibition for Liehberr’s new duty cycle crawler, HS8300HD. One of the interesting features that it has is a Patronic-fuel conservation system, successful on Liebherr’s mobile harbour cranes.
The 220t LTR1220 telecrawler will be at the stand, with applications in installing prefabricated components and on long term energy or infrastructure sites.
One of the standout features of the LTR1220 is a 60m telescopic boom with a larger load moment than other telescopic crawler cranes on the market, Leibherr said. The LTR 1220 telecrawler can carry out installation work in two-hook operation using an erection jib 3.4m long and second hoist gear. It is suited as an auxiliary crane in the installation of windpower systems, and for the handling of windpower components, the company said.
Also, the LTM 1750-9.1 all terrain launched last summer and now available to buy, will be at the stand.
The load capacity positions this crane the second largest at the top of Liebherr’s LTR telecrawler series.
The LTM 1750-9.1 all terrain is notable for its high degree of roadability. The complete telescopic boom can be carried by the nine-axle vehicle during travel on public roads.
The design of LTM 1750-9.1 takes worldwide differences in transport weights and axle load variations into account and is designed for short set-up times.
The company designed a broad range of equipment options to give LTM 1750-9.1 an especially wide operational spectrum.
Different boom systems of LTM 1750-9.1 include a 52m long telescopic boom, telescopic boom Y-guying system, allowing for larger loads and lateral stability, along with many different lattice jibs.
The luffing fly jib extends out to 91m, and there is a special auxiliary jib, with a load capacity of 56t. The luffing of the fixed lattice jib can optionally be hydraulically moved and operated under load. The maximum achievable dimensions with these are particularly tall 154m height, with 112m reach.
