Liebherr LTM 1120/1

Crane Carrier Features

• Frame and Outriggers: The LTM 1120/1 boasts a Liebherr-designed box-type frame, constructed from high-tensile, torsion-resistant structural steel. It is equipped with a 4-point outrigger system, enabling both horizontal and vertical extension for optimal stability during operations.
• Engine and Transmission: Powered by an 8-cylinder Liebherr D9408 TI-E diesel engine, this crane delivers 400 kW (544 HP) at 2100 min^-1, with a maximum torque of 2230 Nm at 1575 rpm. The engine is paired with an Allison automatic transmission featuring a torque converter and hydrodynamic retarder, facilitating smooth and efficient power transmission across a range of terrains.
• Axles and Suspension: The crane features five steered axles with planetary gears and differential locks, and a sophisticated hydro-pneumatic suspension system that enhances its mobility on uneven surfaces.

Crane Superstructure Capabilities

• Crane Engine and Control System: The superstructure is driven by a 4-cylinder Liebherr diesel engine, ensuring efficient crane operations. The advanced crane control system supports load sensing and allows four working motions to be performed simultaneously, enhancing operational efficiency.
• Hoisting and Luffing Gear: Equipped with an axial piston fixed displacement motor and integrated planetary gear within the hoist drum, the LTM 1120/1 ensures precise load handling. The luffing gear features a safety check valve for additional security during lifting operations.
• Safety Features: The crane includes multiple safety devices, such as the LICCON safe load indicator, hoist limit switch, and safety valves against pipe burst, ensuring operations are conducted safely and effectively.

Additional Equipment

• Telescopic Boom: The crane’s telescopic boom comprises 1 base section and 5 hydraulically extendable sections, allowing it to reach up to 56 meters. This feature provides significant versatility in handling various lifting requirements.
• Folding Jib: An optional folding jib, extending from 11.2 to 28 meters, can be mounted on the telescopic boom at angles of 0°, 15°, 30°, or 45°, providing additional reach and flexibility in lifting operations.
• Drive and Tyre Options: The crane offers a 10 x 8 drive configuration, with additional drive on the 2nd axle and various tyre sizes available to suit different operational needs.

The Liebherr LTM 1120/1 combines high lifting capacities with advanced technological features and strong mobility, making it a highly capable and versatile crane for a variety of industrial and construction applications. Its extensive range of equipment options and safety systems ensures it can perform in both challenging environments and routine lifting tasks with ease and efficiency.
