Liebherr has introduced the LTM 1090-4.3 mobile crane, equipped with the latest LICCON3 control system, at CONEXPO 2026 in Las Vegas, marking a significant upgrade to its four-axle crane range. The new model builds on the established LTM 1090 series while incorporating advanced control technology, improved lifting performance, and enhanced operator comfort.
The LTM 1090-4.3 represents the next generation of the company’s Liebherr Computed Control (LICCON) platform. The third-generation LICCON3 system features a new software architecture, faster data processing capabilities, increased memory capacity, and a modern data bus structure, allowing improved crane operation, diagnostics, and system integration. Despite these upgrades, the operating concept remains similar to previous systems, enabling operators familiar with earlier LICCON controls to transition easily.
A redesigned operator cab and driver’s cab accompany the new control system. The superstructure cab now features a large touchscreen display with an updated interface, providing clearer operational data and improved usability. The driver’s cab includes a multifunction steering wheel, improved instrumentation layout, and larger digital displays. Both cabins are equipped with an automatic heating and air-conditioning system with a sun sensor that adjusts climate settings depending on sunlight conditions.
The crane remains in the 110-US-ton (approximately 90-tonne) lifting class and retains the 60-metre telescopic boom used in the previous model. However, lifting capacity has been improved, particularly when the boom is fully extended and positioned at steep angles, making it suitable for applications such as tower crane assembly and high-reach lifting tasks.
Mobility remains a key design feature of the four-axle crane. The LTM 1090-4.3 can operate with axle loads of 10, 12, or 16 tonnes, allowing it to meet varying road regulations in different countries. The crane also includes a quick-change ballast system, enabling operators to adjust ballast configurations efficiently depending on transportation requirements and lifting conditions. With a 12-tonne axle load, the crane can carry up to 8.8 tonnes of counterweight, enabling many lifting operations without the need for additional ballast transport.
The model incorporates Liebherr’s proven technologies such as VarioBallast® and VarioBase®, which optimize crane stability and lifting performance by adjusting the ballast radius and support base depending on the available setup space. In addition, ECOdrive and ECOmode systems help reduce fuel consumption and noise levels during crane operation.
Several driver assistance systems have also been integrated to enhance safety. These include the Blind Spot Information System (BSIS) and the Moving-Off Information System (MOIS), which help detect pedestrians and cyclists around the crane when travelling on public roads. The machine is also prepared for RemoteDrive, allowing the crane to be manoeuvred via radio remote control from outside the cab when operating in tight job-site environments.
With the introduction of the LTM 1090-4.3, Liebherr continues its strategy of upgrading established crane platforms by integrating new digital control systems and improved design features, ensuring higher efficiency, safety, and operational flexibility for modern construction and lifting applications.
