Liebherr LTM 1225

Crane Carrier Specifications

• Engine and Transmission: The LTM 1225 is powered by a Liebherr D9408 TI diesel engine, delivering 400 kW (544 HP) at 2100 rpm with a maximum torque of 2180 Nm at 1200 rpm, ensuring strong performance and reliability. The crane’s transmission system includes an Allison type CLBT 755 with torque converter and hydrodynamic retarder brake, enhancing maneuverability and safety on various terrains.
• Chassis and Axles: The crane chassis is built for durability and strength, accommodating all six axles that are sprung and with the first, third, and fifth axles steered. This setup allows for exceptional mobility and stability during transportation and operation.
• Suspension and Brakes: Featuring hydropneumatic suspension and automatic leveling, the LTM 1225 ensures smooth operation across uneven surfaces. The service brake system operates on all wheels with a dual circuit system, supplemented by a spring-loaded hand brake for additional safety.

Crane Superstructure Capabilities

• Telescopic Boom and Hoist Gear: The superstructure of the LTM 1225 comprises a telescopic boom extending from 15.1 meters to 60 meters, with a telescoping ram and boom section interlocking device. The hoist gear features an axial piston variable displacement motor, integrated with a planetary gear for precise lifting operations.
• Safety and Control Systems: Equipped with advanced safety devices, including the LICCON safe load indicator and hoist limit switch, the crane ensures operational safety. Crane operations are controlled via two self-centering control levers, allowing for simultaneous and independent movements, which significantly enhances operational efficiency.

Additional Features and Equipment

• Lattice Jibs and Additional Equipment: The crane can be fitted with a fly jib extending up to 42 meters and a luffing jib up to 63 meters, greatly enhancing its operational range and versatility. It also offers a second hoist gear for complex lifting operations involving two-hook operation.
• Comfort and Ease of Use: The operator’s cabin is designed to provide maximum comfort and control, featuring safety glazing, comfortable armrest seats, and standardized controls for ease of use.

Operational Advantages

• Automated Lubrication and Electrical Systems: The LTM 1225 includes a central lubricating system ensuring all crucial components, such as the boom bearing and winch bearings, are automatically lubricated. This reduces maintenance time and extends the lifespan of mechanical parts. The electrical system, powered by 24 VDC and two batteries, is optimized for reliable and long-term operation.

Overall, the Liebherr LTM 1225 combines powerful lifting capabilities with advanced engineering and safety features, making it suitable for demanding lifting tasks in various industrial and construction environments.
