In mid-March, Liebherr highlighted a new rough-terrain crane with the longest boom and highest lift capacity in the two-axle market segment. The company showed off the new LRT 1130-2.1 at the ConExpo-Con/Agg trade show in Las Vegas, Nevada.
The new rough-terrain model has a 140-ton (130-metric ton) load capacity and a 197-foot (60-meter) telescopic boom. It is also sized for economical transport via lowboy trailer.
Boom Options
The LRT 1130-2.1 has a six-section boom that uses Liebherr’s Telematik high-speed telescopic system to extend and bolt fully automatically. The crane can attain a maximum hoist height of 279 ft (85 m) and a maximum radius of 217 ft (66 m) with assistance from a lattice extension and a single- or double-folding jib. Either jib can hydraulically tilt from 0 to 40 degrees, or be mounted at 0, 20, or 40 degrees. The folding jib is located on the right side of the boom, while the left side allows an assembly jib to be attached. An available rooster sheave is side-folding and may be operated in a two-line configuration.
Lowboy-Transportable
The new LRT 1130-2.1 is 11.2 ft (3.4 m) wide, 12.6 ft (3.85 m) in height, and 30.7 ft (9.4 m) in length. For transport, the machine can be reduced to 98,750 pounds (44,800 kilograms), or 106,000 lbs (48,000 kg) with its folding jib and hook block included.
The crane’s 44,100 lbs (20,000 kg) of counterweight and additional equipment can be hauled without a permit by standard means. Ballasting rams can help the three counterweight slabs attach to the crane’s slewing platform during self-assembly.
Safety Foremost
Liebherr engineered the LRT 1130-2.1 for safe crane operation. It complies with global safety standards including U.S., European, and Australian regulations. The crane monitors the positions and status of its outriggers, ballast, double-folding jib option, and jib angle for safety purposes, and is equipped with measures to prevent the disabling of these systems.
With Liebherr’s VarioBase as a standard feature, the LRT 1130-2.1 can extend its outriggers independently to any length. VarioBase works in conjunction with the crane’s LICCON controller’s load moment limiter to keep the machine’s lifting activity within safe parameters.
Like other Liebherr LRT models, the LRT 1130-2.1 has a wide, tilting crane cab designed for easy operation of the machine. The cabin has an electronically extending platform for safe access.
Working In The Rough
The LRT 1130-2.1 is designed for off-road, rough-terrain performance. It’s powered by a 252-horsepower (188-kW), six-cylinder Cummins engine with 875 pounds-foot (1,186 newton-meters) of torque and unrestricted compatibility with hydrogenated vegetable oil (HVO) fuel. A Dana six-speed powershift transmission puts the power to the ground.
The crane can travel at up to 12 mph (20 km/h). It is a 4 x 4 x 4 model with all-wheel and crab steering modes available.
