The Liebherr LTM 1200-5.1 is a 200-tonne maximum lifting capacity, five-axle all-terrain mobile crane manufactured by Liebherr-Werk Ehingen GmbH in Germany. Designed for heavy lifting applications requiring substantial lifting height, long boom reach and road mobility, the LTM 1200-5.1 incorporates a 72-metre telescopic main boom, optional lattice jib extensions and Liebherr’s LICCON2 electronic crane control system. The crane combines a high-capacity telescopic boom with a compact five-axle carrier, making it suitable for structural steel erection, industrial plant construction, machinery installation, infrastructure development and other lifting applications requiring considerable working height and outreach. The model is documented in Liebherr’s 2012 technical data publication.

Telescopic Main Boom and TELEMATIK Boom Extension System

The Liebherr LTM 1200-5.1 features a seven-section telescopic main boom consisting of one base section and six telescoping sections. The boom has a retracted length of 13.2 metres and extends hydraulically to a maximum length of 72 metres, providing a wide range of lifting heights and working radii without requiring additional lattice boom sections.

The main boom incorporates Liebherr’s TELEMATIK rapid-cycle telescoping system, which allows the six telescopic sections to be extended individually. This arrangement provides flexibility in selecting boom configurations for different lifting requirements. According to Liebherr’s 2012 technical specifications, the boom can be extended from 13.2 metres to its full 72-metre length in approximately 638 seconds. The boom luffing mechanism uses a hydraulic differential cylinder with a non-return valve, allowing the boom to reach an inclination of approximately 82 degrees in 65 seconds.

The LTM 1200-5.1 has a maximum rated lifting capacity of 200 tonnes at a 3-metre working radius in the specified over-rear lifting configuration with 76 tonnes of counterweight. Its load charts provide lifting capacities for boom lengths between 13.2 and 72 metres, covering a wide range of working radii and counterweight arrangements. Actual lifting performance depends on the selected boom length, crane configuration, working radius, counterweight and operating conditions.

Swing-Away Lattice Jib and Maximum Boom Configurations

The Liebherr LTM 1200-5.1 can be equipped with an optional swing-away lattice jib ranging from 12.2 to 36 metres in length. The jib is attached to the telescopic boom head and can be positioned at offset angles of 0°, 22.5° and 45°, allowing additional lifting height and outreach when working around structural obstructions or at elevated installation points.

The swing-away jib incorporates an integrated 5.4-metre erection jib, which provides an additional attachment configuration for specific lifting requirements. An optional hydraulic adjustment cylinder allows the swing-away jib angle to be controlled between 0° and 45°, providing further flexibility in positioning loads.

For applications requiring a higher jib attachment point, Liebherr offers an optional 7-metre lattice boom extension. This extension raises the attachment point of the swing-away jib by 7 metres, enabling additional lifting configurations for elevated work. The manufacturer’s lifting-height diagrams include configurations using the telescopic boom, the 7-metre extension and lattice jib arrangements with chart scales reaching 116 metres. These diagrams document the crane’s long-reach capabilities, although the achievable hook height depends on the selected attachment, boom angle and lifting configuration.

The combination of a 72-metre telescopic main boom, variable-length swing-away jib and optional lattice boom extension makes the LTM 1200-5.1 suitable for lifting applications requiring both high lifting capacity and extended vertical reach.

Five-Axle Carrier Chassis and All-Terrain Mobility

The Liebherr LTM 1200-5.1 is mounted on a five-axle carrier constructed using a weight-optimised, torsion-resistant box-type frame manufactured from high-tensile structural steel. The crane has an overall vehicle length of approximately 15.9 metres, with a carrier chassis length of approximately 13.38 metres. Depending on the tyre configuration, the carrier width ranges from approximately 3.0 to 3.1 metres, with an overall height of approximately 3.95 to 4.0 metres.

All five axles are steerable, providing manoeuvrability for a crane of this lifting capacity. The steering system uses two hydraulic circuits with speed-dependent rear-axle steering and selectable steering programmes for different driving conditions. The carrier incorporates differential locks to improve traction when travelling on construction sites and other demanding surfaces.

The standard drive arrangement includes three driven axles, with an optional 10 × 8 configuration adding drive to the first axle. All five axles are equipped with Liebherr’s hydro-pneumatic Niveaumatik suspension, which can be hydraulically locked as required. This suspension arrangement contributes to vehicle stability and mobility during road travel and site manoeuvring.

The standard tyre size is 385/95 R 25, with 445/95 R 25 and 525/80 R 25 available as alternatives. Maximum road travel speed is specified as 75 km/h with 385/95 R 25 tyres and 80 km/h with the larger tyre options under the corresponding transmission configuration.

Liebherr Six-Cylinder Carrier Engine and ZF AS-TRONIC Transmission

The Liebherr LTM 1200-5.1 is equipped with a six-cylinder, water-cooled Liebherr diesel carrier engine rated at 390 kW (530 hp), producing a maximum torque of 2,503 Nm. The carrier engine provides the power required for road travel and manoeuvring the five-axle chassis.

The carrier engine is coupled to a ZF AS-TRONIC 12-speed automated gearbox, incorporating automatic transmission control for gear selection during vehicle operation. A ZF Intarder is integrated into the transmission to provide additional braking capability, while a two-stage transfer case with a lockable transfer differential distributes drive torque to the driven axles.

The 2012 Liebherr technical publication identifies exhaust emissions compliance according to Directive 97/68/EC and EPA/CARB requirements. The carrier engine has a fuel tank capacity of 474 litres and an AdBlue reservoir capacity of 40 litres.

The carrier braking system includes dual-circuit servo-assisted pneumatic disc brakes on all axles. Additional braking is provided by an exhaust retarder, Liebherr’s ZBS supplementary braking system and the transmission-mounted ZF Intarder. The parking brake uses spring brake actuators acting on the second and fifth axles.

Separate Liebherr Diesel Engine for Crane Superstructure Operations

Unlike mobile crane designs that use a single engine for both driving and lifting activities, the Liebherr LTM 1200-5.1 is equipped with a separate diesel engine for crane superstructure operations.

The crane engine is a four-cylinder, water-cooled Liebherr diesel engine rated at 180 kW (245 hp), delivering a maximum torque of 1,130 Nm. This engine powers the hydraulic systems responsible for hoisting, boom elevation, slewing and other crane working movements.

The engine drives a diesel-hydraulic system incorporating five axial-piston variable-displacement pumps with servo control and capacity regulation. The hydraulic arrangement provides controlled power delivery to the crane’s working functions, allowing the operator to regulate crane movements according to lifting requirements.

Liebherr specifies a 285-litre diesel fuel reservoir and a 20-litre AdBlue reservoir for the crane engine. The manufacturer’s 2012 technical data also identifies emissions compliance according to Directive 97/68/EC and EPA/CARB requirements.

Counterweight System and Lifting Capacity Configurations

The Liebherr LTM 1200-5.1 has a maximum counterweight configuration of 76 tonnes. The manufacturer’s load charts document additional counterweight configurations of 56 tonnes, 46 tonnes, 36 tonnes, 16 tonnes and 4 tonnes, allowing the crane to be configured for different lifting requirements and site conditions.

The maximum 200-tonne lifting capacity is specified in the 76-tonne counterweight configuration at a 3-metre working radius over the rear of the crane. Other load chart configurations provide lifting capacities over 360 degrees of superstructure rotation, with performance varying according to boom extension, working radius and installed counterweight.

The variable counterweight arrangements allow crane operators to select suitable ballast configurations according to the lifting task, site access and equipment transportation requirements. Lighter counterweight configurations may reduce the amount of ballast transported to a site, while heavier configurations provide greater lifting performance where the applicable load charts permit.

Hoist Winches, Lifting Speed and Slewing Performance

The Liebherr LTM 1200-5.1 is equipped with a hydraulically driven main hoist system incorporating an axial-piston variable-displacement motor, an integrated planetary gearbox and a spring-loaded static brake. The hoist operates through a closed, regulated hydraulic circuit, providing continuously variable lifting and lowering speeds.

According to Liebherr’s technical specifications, the main hoist provides a maximum single-line rope speed of 140 metres per minute and a maximum single-line pull of 105 kN. The hoist uses a wire rope with a diameter of 23 mm and a rope length of 280 metres.

An optional second hoist winch is available for two-hook lifting operations or applications using the swing-away jib. The second hoist has the same specified maximum single-line speed of 140 metres per minute, maximum line pull of 105 kN and rope dimensions as the main hoist.

The crane’s slewing mechanism uses an axial-piston fixed-displacement hydraulic motor, planetary gearbox and spring-loaded static brake. It provides full 360-degree slewing capability, with a continuously adjustable rotation speed ranging from 0 to 1.3 revolutions per minute. This allows the operator to control superstructure rotation and load positioning during lifting operations.

LICCON2 Electronic Crane Control and Safety Technology

The Liebherr LTM 1200-5.1 features Liebherr’s LICCON2 electronic crane control system, which integrates crane operation, load monitoring and diagnostic functions. The system incorporates an electronic safe load indicator, providing monitoring of lifting conditions according to the selected crane configuration.

Crane movements are controlled using two self-centering multifunction joysticks connected to the LICCON electronic control system. The operating controls provide continuously variable adjustment of crane movements, including hoisting and slewing.

The LICCON2 system includes diagnostic and testing functions to assist in monitoring crane components and identifying system faults. Additional safety equipment includes a hoist limit switch and hydraulic safety valves designed to protect against uncontrolled movement in the event of hydraulic pipe or hose failure.

The crane’s electrical systems use modern data bus technology and a 24-volt electrical architecture, with two 170 Ah batteries specified in the manufacturer’s technical documentation.

Hydraulic Outriggers and Crane Setup

The Liebherr LTM 1200-5.1 incorporates a four-point hydraulic outrigger system designed to support the crane during stationary lifting operations. The outriggers extend hydraulically in both horizontal and vertical directions and are operated using a remote control system.

The setup system includes automatic crane levelling and an electronic inclination display, helping operators establish the appropriate working position before lifting begins. The manufacturer’s dimensional diagrams show an extended outrigger footprint of approximately 8.3 metres in width and 8.9 metres in length, depending on the configuration represented.

Proper outrigger deployment, ground preparation and supporting conditions are essential to lifting performance. The permissible load depends on the corresponding lifting chart and the established crane configuration.

Operator Cab and Working Environment

The Liebherr LTM 1200-5.1 features separate carrier and superstructure operator cabs. The carrier cab is constructed from steel and mounted on rubber shock absorbers, with safety glass windows and an interior designed for road driving and vehicle manoeuvring.

The crane superstructure cab provides a large glazed viewing area and can be tilted approximately 20 degrees rearward. This cab-tilting function helps improve the operator’s upward visibility and operating posture when working with the telescopic boom at elevated angles.

The crane’s ergonomically positioned joysticks, electronic displays and integrated control systems allow operators to manage lifting operations from the superstructure cab. These features support controlled operation during high-reach lifting tasks and repeated load-handling activities.
