Liebherr LTM 1200-5.1

Unveiled in 2005, the Liebherr LTM 1200-5.1 quickly became a standout in the five-axle crane category, boasting a 72-meter telescopic boom—the longest in its class at the time. This breakthrough in boom engineering positioned it as a versatile, long-reach machine ideal for a wide spectrum of construction and industrial applications. When fitted with additional jib configurations, such as a hydraulically adjustable folding jib, the crane achieves a maximum lifting height of 101 meters and working radii up to 80 meters.

A defining innovation of the LTM 1200-5.1 is its pneumatic disc braking system, a first for its class. This advancement significantly improved braking response, safety, and control, while also reducing wear and maintenance requirements compared to conventional drum brakes.

Powering the crane is a robust Liebherr six-cylinder turbo diesel engine generating 503 HP, paired with a ZF-AS Tronic 12-speed gearbox equipped with an intarder for enhanced downhill braking. This drivetrain not only ensures strong road and off-road performance but also integrates seamlessly with Liebherr’s ECO Mode, reducing fuel consumption during idling without compromising readiness or lifting response.

Operational precision is facilitated by the TELEMATIK telescoping system, enabling efficient and synchronized boom section extension. The crane’s advanced LICCON2 control system offers intuitive operator controls, real-time diagnostics, load monitoring, and load moment limitation for safe crane operation under varied load scenarios.

Compact for its class, the LTM 1200-5.1 measures 13.38 meters in length, with all five axles steerable, allowing for exceptional maneuverability even in restricted site conditions. Its variable steering programs automatically adapt to speed and angle, improving both control and tire longevity.

Further enhancing its adaptability, the crane is equipped with a load-sensing hydraulic system, which matches hydraulic power output to the lifting demand. Combined with flexible counterweight configurations and fast rigging procedures, the crane offers remarkable versatility across applications, from building infrastructure and wind turbines to high-rise construction.

In conclusion, the Liebherr LTM 1200-5.1 remains a benchmark in the 200-ton class, known for its exceptional boom reach, pioneering braking system, and efficient, operator-friendly technologies. It represents Liebherr’s commitment to blending performance, safety, and economy in a mobile crane designed for modern lifting challenges.
