Liebherr LTM 1230-5.1

Engineering Excellence and Versatility

• Telescopic Boom and Jib Options: The LTM 1230-5.1 extends its reach with a 75-meter telescopic boom, one of the longest in its class, providing an average of 20 percent greater lifting capacity than its predecessor, the LTM 1200-5.1. It supports various jib configurations including a multi-functional folding jib and a 43-meter fixed jib, allowing for versatile setups based on job requirements. The crane can be equipped with up to three straight 7-meter lattice sections acting as telescopic boom extensions, which significantly increases its operational range.
• Innovative Support Systems: With the pioneering VarioBase® and VarioBallast® systems, the LTM 1230-5.1 offers enhanced stability and lifting capacities. These systems allow operators to adjust the counterweight radius and outrigger breadth, optimizing the crane’s performance based on the available space and lifting requirements. This asymmetrical support base can extend up to 8.1 meters at the rear, providing extraordinary lifting capacities, particularly over the rear working area.

Performance and Efficiency

• Powerful Drive System: Powered by a six-cylinder Liebherr diesel engine delivering 400 kW (544 bhp) and 2,516 Nm of torque, the LTM 1230-5.1 is equipped to handle demanding tasks efficiently. The engine is paired with the innovative 12-speed ZF TraXon gearbox, which includes functionalities like ECOmode for reduced engine speeds and noise, enhancing comfort and operational efficiency.
• Advanced Control and Safety Features: The crane features the latest in crane technology advancements including the LICCON controller for real-time capacity calculation. This digitalization aids in maximizing the crane’s performance while ensuring operational safety. The Hill Holder feature assists with starts on slopes, making the crane easier to handle in challenging terrains.

Environmental and Operational Considerations

• Eco-Friendly Design: The LTM 1230-5.1’s engine meets Stage V exhaust emissions standards, reflecting Liebherr’s commitment to environmental sustainability. The single-engine concept not only reduces weight but also optimizes fuel consumption, particularly with the integration of ECOmode, which minimizes fuel use and noise during crane operations.

Conclusion: The Liebherr LTM 1230-5.1 sets new standards in the mobile crane industry for its length, power, versatility, and innovative technology. It is specifically tailored for high-demand tasks like tower crane erection and wind turbine maintenance, offering operators unprecedented capabilities in a 5-axle crane configuration. This model exemplifies Liebherr’s leadership in crane technology and its dedication to enhancing user and environmental safety.
