The line-up of new crane models presented by Liebherr Cranes during Bauma 2007 this week, is extensive. It includes a new fast-erecting crane, two telescopic truck cranes, three- and five-axle mobile cranes, four telescopic handlers, and a variation on its flagship HS 895 HD duty-cycle crawler.
In the mobile crane market, one of the highlights in the Liebherr stand will be the nine-axle LTM 11200-9.1 all-terrain crane with a powerful maximum lifting capacity of 1,200 tons. This new flagship model's eight-section boom is 52.5 feet longer than Liebherr's now second largest crane, the LTM 1500-8.1. The 328-foot telescopic boom consists of a base section and seven telescopic parts. A 180-foot radius is achieved with the help of a 10-foot lattice head section. The luffing fly jib can be extended to 413 feet and reaches lifting height of up to 558 feet.
Other mobile cranes at the Bauma include Liebherr's two new truck-mounted telescopic cranes and two new all-terrain cranes. The 50-ton, four-axle LTF 1045-4.1 and the 39-ton, three-axle LTF 1035-3.1 truck cranes are designed to be straightforward taxi cranes that have lower axle loads than all-terrain cranes and can be driven fully equipped on public roads. Compared to previous LTF series models, the load capacities of the LT 1045-4.1 and LTF 1035-3.1 are up 35 percent and the telescopic booms are 15 percent longer.
The 143-ton, five axle LTM 1130-5.1 features a 197-foot telescopic boom that can be extended with a 35- to 62-foot swing-away fly jib and two 23-foot lattice sections. The 55-ton LTM 1050-3.1 is the successor to the LTM 1045-3.1. It sports a telescopic boom extended by 13 feet, and with a 55-foot biparted swing-away jib, achieves a hook height of 177 feet.
The company will extend its mobile construction crane line with the three-axle MK 63. The smallest member of the series, the “compact, flexible and extremely adaptable taxi crane” allows a maximum radius of 119 feet. Designing in a 45-degree super-raised working angle, Liebherr can now boast hook heights of up to 157 feet, “something never before possible with a mobile construction crane,” according to product literature.
Combining the advantages of a hydraulic fold-away jib and a telescopic lattice tower, the 26 K.1 fast-erecting crane will be the first shown at Bauma. The newest member of the company's K crane series is also the smallest, and during its design, Liebherr paid particular attention to ease of use and assembly. Maximum load capacity is 2.75 tons, and at a radius of 85 feet, the crane can lift 1 ton at jib
end. Other features include a 121 feet maximum hook height, 40 super-raised working angle, and jib adjustments from 0 to 20 and 20 to 40 degrees with the use of a hydraulic guying system.
Introduced last fall, the four telescopic handlers • the TL 435-10, the TL 435-13, TL 445-10 and TL 442-13 • will first be shown internationally at Bauma. These machines range in lift heights from 33 to 43 feet and have maximum lifting capacities between 3.5 to 5.4 tons. All four are equipped with turbocharged four-cylinder in-line engines with outputs of 109 hp.
Bauma will also be the sight of two crawlers. Liebherr's HS 895 HD duty-cycle crawler is a heavy-duty alternative to the standard HS 895
HD crawler and features a 912-hp, 12-cylinder diesel engine and pulling force of 50 tons. Liebherr's newly-developed LR 1300 crawler will also be unveiled. With a maximum load capacity of 330 tons, it falls between the LR 1280 and LR 1350/1 models.
Lastly, the crane manufacturer will present a derrick crane designed to dismantle cranes on tall buildings, bridge pylons, and telecommunication towers. The 200 DR 5-10 can be configured with load moments of 110 or 220 tons.
