LTM 1055-3.2  Liebherr crane - load chart, specs & dimensions (2008 - 2026)

High mobility and efficiency

A high performance 6-cylinder Liebherr turbo diesel engine with 270 kW/367 HP provides for dynamic driving performance. The 12-speed ZF-gearbox with automatic gear change system AS-TRONIC grants high efficiency and best comfort. Reduced fuel consumption due to high number of gears and high degree of efficiency of the dry clutch. Best manoeuvrability and minimum crawl speed by means of the 2-stage transfer gearbox. ABV - automatic blocking preventer with ASR anti-slip control.

Active rear axle steering

The rear axles are electro-hydraulically actively steered depending on the speed and the steering angle of the front axles. 5 steering programs (P) are preselectable by push button. Distinct reduction of the tyre wear. Improvement of the manoeuvrability. Stable driving performance also at high speeds. All 3 axles steerable.

P2 All-wheel steering

The axles 2 and 3 are turned by the steering wheel depending on the steering angle of the front axle to provide for the smallest turning radius.

P4 Reduced swing out

The axles 2 and 3 are turned depending on the wheel turn of the 1. axle to minimize the back swing of the rear of the chassis.

P5 Independent rear axle steering

The axle 1 is steered by the steering wheel, the axles 2 and 3 are steered by push buttons independently from the steering angle of the axle 1.

Touch displays

Below the joy sticks integrated in the armrests the touch display is installed, with which the various operational functions can be selected. This includes, among others, the drive and steering programs of the chassis, the axle suspension, the supporting of the crane, the adjustment of the working floodlights, as well as heater and air condition controls.

Modern driving cab and crane cab

The modern driving cab as well as the backwards tiltable crane cab offer a comfortable and functional working environment. The control elements and displays are arranged according to ergonometric factors. Thus a safe and fatigue-proof working is assured.

The fully automatic telescoping system

Improvement of capacities at long booms and large radii due to lightweight telescoping system: 1-stage hydraulic cylinder with hydraulically operated drive pin Maintenance free telescoping Telescoping fully automatic Simple operation, supervision of telescoping at the LICCON monitor.

With proven components

The drive components for the crane operation are designed for high performance and provide for sensitive and precise handling of the load. They are specially tuned for the crane operation and proved in severe long-term tests. Crane drive from diesel engine in chassis Optimized fuel consumption by electronic engine management Diesel-hydraulic crane drive, open hydraulic circuits with electric LOAD SENSING-control, 4 working motions simultaneously possible Electric/electronic SPS-crane control via the LICCON-computer system Comfortable armrest controls with 2 self-centering 4-fold multifunctional joysticks, stepless control of all crane motions, with winch and slewing gear indicators, electronic precontrol Slewing gear standard reversible from open to hydraulically locked, so the slewing motion can be optimally adapted for the different operation conditions, e.g. sensitive for installation work or fast for cycle work.

Attaching and detaching of the hook block

The BTT – Bluetooth terminal – offers the crane driver the possibility to attach the hook block to or detach it from the front bumper within sight by remote control of the hoist winch and the luffing cylinder of the telescopic boom.

Supporting the crane

By use of the BTT the mobile crane can be comfortably and safely supported on the outriggers. Engine start/stop, speed regulation, electronic level display and automatic support levelling are available as standard. Optionally, the supporting forces can also be displayed on the BTT.

Colour monitor

The readability of the data on the monitor of the LICCON2 control system in the crane cab is enhanced by the colour display. Warnings and crane utilization are considerably better recognized.

Powerful, long telescopic boom and functional lattice extensions

The telescopic boom consists of the base section and 4 telescopic sections, which can be comfortably and automatically extended and pinned to the requested length by the thousand fold proven single cylinder telescoping system TELEMATIK. 40 m long telescopic boom 9.5 m – 16 m long double swing-away jib, attachable at 0°, 20° and 40° Rooster sheave, foldable sidewise 2.5 m long assembly jib.

High capacities with full counterweight as well as with partial counterweight offer a wide application of operations

High lateral stability due to the oval boom profile Optimized capacities due to the numerous extension variations Capacity 10.1 t at 40 m long telescopic boom.

High capacities at the unpinned telescopic boom

High telescopable capacities due to interpolation Separate charts for holding of loads at unpinned telescopic lengths Display at LICCON monitor.

Mounting of counterweight – only a matter of minutes

Multitude of counterweight variations from 4.7 t to 12 t Fast ballasting with keyhole-technology from the crane cabin Compact counterweight dimensions, at 12 t counterweight only 2.54 m counterweight width Tail swing only 3.5 m 36 t total weight including 7 t counterweight at 12 t axle load.
