Liebherr LTC1050-3.1

Unveiled at INTERMAT 2015, the Liebherr LTC 1050-3.1 is a 50-tonne capacity compact city-class crane that builds upon the proven foundation of its predecessor, the LTC 1045-3.1. This new generation three-axle mobile crane offers increased lifting capacity and improved technological features while retaining the same maneuverable compact footprint, making it ideal for confined or urban construction sites.

The LTC 1050-3.1 is fitted with a 6-section telescopic boom extending up to 36 meters. Additionally, it features a 13-meter double folding swing-away jib, which includes a 1.5-meter erection jib that can be offset at 0°, 20°, 40°, or 60°, expanding its flexibility for challenging lifts. This gives the crane a maximum tip height of nearly 50 meters when fully configured.

The crane’s structural upgrade to high-grade steel (S1300) with a tensile strength of 1,300 N/mm² allowed Liebherr to raise the rated lifting capacity from 45 tonnes to 50 tonnes. The boom’s buckling and torsion-resistant design ensures strength and stability across the entire working range. To complement this, the crane is equipped with LICCON2 intelligent control and the VarioBase® outrigger system, allowing the crane to automatically optimize lifting performance depending on individual outrigger extension lengths, enhancing both safety and capacity on uneven terrain.

A major feature of the LTC 1050-3.1 is its telescopic, elevating cab, which improves operator visibility and comfort. The cab can be hydraulically raised up to 7.8 meters, with 20° rear tilt and slide-away access via telescoping arm, significantly improving visibility for lifts over obstacles or in congested areas.

Mobility is also a highlight of this machine. The 36-tonne gross weight configuration includes the full 6.5-tonne counterweight, hook block, double folding jib, and 16.00 R25 tyres — all carried within a 12-tonne-per-axle configuration. This allows for travel on public roads without requiring disassembly or additional transport vehicles. The detachable storage box adds convenience for transporting lifting accessories and outrigger mats.

Powering the LTC 1050-3.1 is a 260 kW (354 hp) Mercedes-Benz diesel engine (EU Stage IV/ EPA Tier 4 Final) with a maximum torque of 1400 Nm. This engine is mated to a ZF powershift transmission offering 12 forward and 2 reverse gears, and the crane drives with a 6×6 configuration. A hydro-pneumatic suspension and 3-axle steering system (with selectable rear axle programs) provide excellent maneuverability and ride quality on-site and on-road. It boasts a top road speed of 80 km/h and a turning radius of just 11.98 meters.

The LTC 1050-3.1 also includes extensive safety and monitoring systems. LICCON2 oversees load control, boom position, and operating parameters. Braking systems include servo-air disc brakes on all axles, spring-loaded hand brakes, and an exhaust retarder. Optional safety upgrades include the Telma Eddy current brake and second hoist gear for dual-line operation.

In essence, the LTC 1050-3.1 combines high lifting performance, compact size, exceptional roadability, and modern operator assistance systems into a single, road-ready mobile crane solution. It is especially suited for urban construction projects, industrial plants, and tight access lifting where space and visibility are critical.
