New Single Engine Liebherr Crane To Debut
Liebherr will debut the new model LTM 1160-5.2 190 US-ton mobile crane as the successor to the company’s model LTM 1160-5.1. The load capacity has been increased by around 20 to 25% whilst the telescopic boom has remained at the same length of 203 ft. The vehicle width has been reduced from 9’10’’ to 9’ which Liebherr says means that not only it is easier to drive on public roads but also considerably better on constricted sites.
The superstructure of the new LTM 1160-5.2 is powered by the engine in the crane chassis using a mechanical shaft. This makes the new 5-axle vehicle the second crane model to feature the innovative single-engine drive concept which Liebherr first presented at the Bauma 2013 for the LTM 1300-6.2.
A six-cylinder Liebherr diesel engine which develops 544 hp at 1900 rpm and torque of 2516 Nm at 1350 rpm provides the LTM 1160-5.2 with all the power it needs. The engine complies with the emission regulations of Directive 97/68/EC - Stage 4 and Regulation EPA/CARB – Tier 4 final in the USA.
The engine output is transferred to the crane axles via the 12-speed ZF-AS Tronic gears. The intarder, a zero wear hydrodynamic brake integrated in the gearbox, acts as a retarder. In addition a Telma eddy current brake is available as an option. Like almost all LTM mobile crane models today, the LTM 1160-5.2 features pneumatic disc brakes. The rear axles of the new 190 US-ton mobile crane have active electro-hydraulic steering depending on the vehicle speed. This increases the maneuverability of the vehicle and drastically reduces tyre wear. Five steering programs can be selected with the touch of a button.
