Liebherr LTM 1150-6.1

The LTM 1150-6.1 was first showcased at Vertikal Days in June 2009 at Haydock Park racecourse, Merseyside. This model is part of Liebherr’s continuous innovation in mobile crane technology, offering enhanced lifting capacities and a long telescopic boom designed for a wide range of lifting tasks.

Crane Carrier Specifications

• Frame and Outriggers: Constructed with a high-tensile structural steel box-type frame, the LTM 1150-6.1 includes a 4-point support system with fully hydraulic horizontal and vertical operation. This setup provides a stable base for high-capacity lifting.
• Engine and Drive System: Powered by an 8-cylinder, water-cooled Liebherr diesel engine, producing 400 kW (544 hp), the crane features a 12-speed ZF-TC-TRONIC gearbox with a torque converter, ensuring smooth and efficient power transmission suitable for various terrain challenges.
• Advanced Steering and Braking Systems: The crane includes advanced features such as active speed-dependent rear axle steering and pneumatic disc brakes, enhancing maneuverability and safety.

Crane Superstructure Capabilities

• Telescopic Boom and Jib: The superstructure boasts a 66-meter long telescopic boom, supplemented by a 19-meter long double swing-away jib that can be hydraulically adjusted between 0° and 40°. This configuration allows for significant versatility in reaching over obstacles and performing complex lifts.
• Safety and Operation Systems: Equipped with state-of-the-art safety and operational systems, including the LICCON2 control system that offers enhanced user interaction and safety protocols, ensuring efficient and safe operations.

Innovative Features and Additional Equipment

• Counterweight and Load Management: The crane carries 15 tons of ballast with a total weight of 72 tons, maintaining a manageable axle load of 12 tons, which is critical for compliance with transportation regulations. The variable counterweight system allows for quick adjustments, optimizing crane performance for each specific task.
• Mobility and Setup Efficiency: Despite its substantial capabilities, the LTM 1150-6.1 features a compact design, enabling it to operate in confined spaces typically challenging for larger cranes. Its innovative steering programs and hydro-pneumatic suspension system enhance its ability to navigate and set up quickly on varied job sites.

The Liebherr LTM 1150-6.1 represents a significant advancement in mobile crane technology, combining high lifting capacity with superior mobility and safety. Its introduction reflects Liebherr’s commitment to delivering powerful and flexible lifting solutions that meet the evolving needs of modern construction and industrial projects.
