Liebherr LTM11200-9.1

The Liebherr LTM 11200-9.1 stands as a milestone in mobile crane engineering, holding the title of the strongest telescopic mobile crane in the world. Introduced at Bauma 2007, this 9-axle all-terrain crane has a maximum lifting capacity of 1,200 tonnes and offers unparalleled reach, height, and lifting capability in its class.

At the core of its design is a 100-meter telescopic boom, extendable via a 22-meter telescopic boom extension (10 m + 2 x 6 m). It can lift 65 tonnes at 100 meters boom length with the Y-guying system attached. With additional jib attachments, including a 126-meter luffing fly jib and a 60.5-meter hydraulically adjustable fixed jib, the crane can achieve a maximum lifting height of 199 meters​.

One of the LTM 11200-9.1’s most remarkable features is its modular boom assembly. The 80-ton boom is transported separately and installed using either an auxiliary crane or Liebherr’s own boom support jack system, which allows the crane chassis to slide beneath the elevated boom for quick and space-efficient mounting​.

Counterweight configuration is highly adaptable, comprising 202 tonnes total weight, including a 22-ton base plate, sixteen 10-ton plates, and four 5-ton plates. The counterweight can be assembled without the need for an auxiliary crane, and the weights are interchangeable with other Liebherr cranes, enhancing logistics and cost-efficiency​.

Chassis and driving performance are optimized for jobsite flexibility. The LTM 11200-9.1 features hydropneumatic axle suspension (Niveaumatik), all-axle steering, and speed-dependent active rear-axle steering, providing superior maneuverability and reduced tyre wear. It is powered by a 500 kW (680 hp) 8-cylinder Liebherr diesel engine, driving through a ZF 12-speed automated transmission with torque converter. The crane can drive with significant equipment installed, minimizing site setup time​.

The superstructure is powered by a 6-cylinder Liebherr engine (270 kW), optimized for fuel efficiency and smooth operation. The entire crane is controlled by Liebherr’s in-house LICCON system, integrating LML (load moment limiter), onboard diagnostics, and the LSB data bus system, ensuring responsive and safe control of all crane functions. The BTT (Bluetooth Terminal) allows wireless operation of boom assembly, supporting, and ballasting, giving operators a close and clear view of the crane during setup​.

Milestones:

• 2008: Mammoet takes delivery of the first LTM 11200-9.1, deploying it in Amsterdam.
• 2010: ACT (Arabian Consolidated Trading) becomes the first owner in Saudi Arabia.
• 2014: The 50th unit is delivered to Yamagata in Japan, marking the crane’s popularity and global reach.
• 2017: Max Bögl uses the crane to erect the world’s tallest wind turbines, lifting over 90-ton concrete rings to more than 240 meters in total height.

Overall, the LTM 11200-9.1 is a crane that blends record-breaking performance, operator convenience, and transport efficiency, making it the go-to solution for mega lifts in the wind energy sector, industrial installations, and large-scale infrastructure worldwide.
