Liebherr LTM 11200-9.1 Load Chart PDF + Specifications

The Liebherr LTM 11200-9.1 is a 1,200-tonne class, nine-axle all-terrain mobile crane developed and manufactured by Liebherr-Werk Ehingen GmbH in Germany. First introduced in 2007, the crane was designed for exceptionally demanding heavy lifting applications requiring high lifting capacities, extended boom lengths and the mobility of a wheeled crane carrier. One of its defining characteristics is the 100-metre telescopic main boom, which established the LTM 11200-9.1 as a significant development in large-capacity mobile crane technology. The crane can be configured with alternative telescopic boom systems, telescopic boom guying equipment, fixed lattice attachments and luffing lattice jibs, providing versatility for wind turbine erection, power generation projects, petrochemical plant construction, industrial installations and major infrastructure works.

Telescopic Main Boom and T7 Boom Configuration

The Liebherr LTM 11200-9.1 is equipped with a seven-section T7 telescopic main boom, consisting of a base section and six telescoping sections. The main boom extends from 18.3 metres to a maximum length of 100 metres, providing exceptional lifting height without requiring a conventional lattice main boom.

According to Liebherr’s 2013 load charts, the T7 boom can be operated at lengths of 18.3, 24.1, 29.9, 35.8, 41.6, 47.5, 53.3, 59.1, 65, 70.8, 76.7, 82.5, 88.3, 94.2 and 100 metres. The extensive range of telescoping positions enables the operator to select an appropriate boom configuration according to load weight, working radius and lifting height requirements.

The telescopic boom incorporates Liebherr’s established TELEMATIK boom extension technology, allowing the individual telescopic sections to be positioned according to the selected lifting configuration. Its telescopic construction reduces the need for extensive lattice boom assembly when undertaking high-reach lifting operations.

The manufacturer’s T7 load charts document lifting operations through 360 degrees of superstructure rotation with 202 tonnes of counterweight. For the T7 boom configuration, the published charts show lifting capacities of up to 213 tonnes at short working radii under the specified conditions. These figures represent the capacities of that particular load-chart configuration rather than the crane’s overall nominal 1,200-tonne capacity.

The 100-metre telescopic main boom makes the LTM 11200-9.1 particularly suited to applications requiring substantial hook height, including tall industrial structures, wind turbine components and elevated infrastructure installations.

Alternative T3 Telescopic Boom Configuration

In addition to the long T7 telescopic boom arrangement, the Liebherr LTM 11200-9.1 can be configured with a shorter T3 telescopic boom system. This alternative arrangement provides the foundation for a separate range of lattice boom and luffing jib configurations.

Liebherr’s 2013 load-chart publication includes dedicated lifting capacities for the T3 telescopic boom, the guyed T3Y configuration and several combinations involving fixed and luffing lattice attachments.

The shorter telescopic boom arrangement is particularly relevant when extensive lattice jib systems are required. By using an appropriate telescopic boom base in combination with lattice extensions, the crane can be configured for applications requiring elevated lifting positions and long working radii.

The T3 system forms the basis for configurations identified in the manufacturer’s documentation as T3N, T3F, T3NZF, T3YVEN, T3YV2VEN, T3YVEF and T3YVENZF. Each arrangement has dedicated lifting capacity tables reflecting its structural configuration, boom length, working radius and lifting geometry.

The availability of both T7 and T3 configurations allows the LTM 11200-9.1 to undertake different categories of heavy lifting work, ranging from long telescopic boom operations to projects requiring extensive lattice boom and jib combinations.

Telescopic Boom Guying System

The Liebherr LTM 11200-9.1 can be equipped with a Y-shaped telescopic boom guying system designed to improve the structural stability and lifting performance of the telescopic boom under appropriate working conditions.

The guying arrangement supports the telescopic boom through an additional structural bracing system, helping to control boom deflection and improve lifting performance in selected operating configurations.

The manufacturer’s technical documentation identifies the T7Y configuration for the guyed seven-section telescopic boom and the T3Y configuration for the guyed three-section telescopic boom system.

The 2013 load charts provide separate lifting capacities for these guyed arrangements, reflecting their different lifting characteristics compared with the corresponding unguyed boom configurations.

The Y-guying system is particularly relevant to heavy lifting operations involving long boom extensions and large working radii, where boom stiffness and structural stability are important factors in lifting performance.

Fixed Jib and Folding Lattice Attachments

The Liebherr LTM 11200-9.1 supports a range of fixed lattice jib configurations that extend the operational flexibility of its telescopic boom systems.

For the T7 telescopic boom, Liebherr’s 2013 load charts document fixed and folding jib arrangements under the T7F and T7NZF configuration designations. These configurations incorporate lattice attachments ranging from 6.5 metres upwards, with documented jib lengths including 6.5, 12.5 and 18.5 metres.

The fixed lattice jib arrangements can be configured at offset angles of 0°, 30° and 60°, depending on the attachment and lifting arrangement. These offset positions allow loads to be handled at elevated locations where the main boom alone may not provide the required clearance or access.

Additional fixed lattice arrangements are documented for the T3 telescopic boom system, including T3F and T3NZF configurations.

The fixed jib options provide additional lifting flexibility for industrial assembly, tall structures and work involving overhead obstructions. The allowable lifting capacities depend on the particular attachment, boom length, operating radius and corresponding manufacturer load chart.

Luffing Jib and Extended Boom Configurations

For applications requiring substantial working height and horizontal outreach, the Liebherr LTM 11200-9.1 can be configured with lattice luffing jib systems.

Liebherr’s 2013 load charts document several extensive boom and jib combinations, particularly those based on the T3 and guyed T3Y boom configurations.

The T3N configuration provides a range of lattice jib combinations, while the T3YVEN and T3YV2VEN configurations incorporate additional boom extension and luffing jib arrangements designed for high-reach lifting applications.

These configurations allow the crane to operate with elevated jib attachment points and extended lattice structures, providing flexibility in lifting loads over existing equipment, structures and other site obstructions.

The manufacturer’s lifting-height diagrams illustrate configurations reaching significantly higher than the 100-metre telescopic boom alone. Certain configurations are represented on diagrams with vertical scales extending beyond 120 metres, reflecting the substantial height potential of the crane’s lattice boom and jib systems.

The exact maximum hook height and permissible working radius depend on the selected boom and jib configuration, luffing angle, counterweight and manufacturer lifting charts.

The extensive range of boom and jib combinations makes the LTM 11200-9.1 relevant for power generation facilities, large industrial structures, wind turbine installation and other projects where both lifting height and outreach are critical considerations.

Nine-Axle All-Terrain Carrier and Road Mobility

The Liebherr LTM 11200-9.1 is mounted on a nine-axle all-terrain carrier designed to transport the crane between construction and industrial project locations.

The multi-axle chassis provides the structural foundation for the crane’s heavy-duty superstructure while distributing the travelling weight across nine axles. Its wheeled carrier configuration distinguishes the LTM 11200-9.1 from large lattice boom crawler cranes that typically require dismantling and separate transportation of their track assemblies.

The crane’s carrier incorporates multi-axle steering and suspension technology to support manoeuvrability during road travel and controlled positioning on construction sites.

Due to the overall dimensions and mass of the LTM 11200-9.1, transportation arrangements may involve separating the telescopic boom and other major components from the crane carrier, depending on the transport configuration and applicable road regulations.

The modular transportation concept allows the crane to be deployed on projects where large lifting capacities are required but permanent crawler crane installation may not be practical.

Counterweight System and Load Chart Configurations

The Liebherr LTM 11200-9.1 uses a substantial counterweight system to provide the stability required for heavy lifting operations.

The manufacturer’s 2013 lifting capacity publication includes configurations with 202 tonnes of counterweight, particularly for the 100-metre T7 telescopic boom and related boom extension arrangements.

Counterweight selection is an important factor in determining lifting capacity, especially at extended boom lengths and larger working radii. The crane’s allowable lifting performance varies according to the installed ballast, boom configuration, working radius, operating sector and applicable lifting chart.

The published load charts include numerous combinations of telescopic boom lengths, guying arrangements and lattice jib systems. Each lifting configuration has its own permissible load values, allowing the crane to be configured according to project requirements.

The maximum nominal crane capacity and the lifting capacities recorded in individual boom charts should be considered separately. The 1,200-tonne crane classification does not indicate that this load can be lifted in every operating configuration.

Slewing and Hydraulic Lifting Operations

The Liebherr LTM 11200-9.1 features a rotating crane superstructure designed for heavy lifting operations using its telescopic boom and lattice jib systems.

The manufacturer’s 2013 load charts document 360-degree lifting configurations, allowing the crane to perform lifts across the full slewing range when the selected load chart and crane setup permit.

Crane movements include boom elevation, telescoping, hoisting, slewing and, where fitted, lattice jib luffing. These functions enable the operator to position heavy loads at different elevations and working radii.

The crane’s hydraulic and electronic control systems are designed to regulate lifting movements and support coordinated operation of the boom, winches and superstructure.

The precise slewing speeds, hoisting speeds and hydraulic operating parameters are not stated in the supplied 2013 load-chart booklet and should be referenced from the corresponding Liebherr technical specification document.

Crane Control and Lifting Safety

The Liebherr LTM 11200-9.1 incorporates Liebherr’s LICCON electronic crane control technology, which supports the monitoring and operation of the crane’s lifting functions.

The crane control system provides the operator with information relevant to crane configuration, lifting performance and operating conditions.

The large number of available boom and jib arrangements makes accurate configuration selection particularly important. Operators must use the lifting chart corresponding to the installed equipment, counterweight configuration and working geometry.

Liebherr’s 2013 load-chart publication separates the lifting capacities into specific T7, T7Y, T3, T3Y and lattice jib combinations, providing detailed information for planning and evaluating lifting operations.

The load charts are intended to be used together with the crane’s operating instructions and the applicable equipment documentation. Lifting capacities must account for the working radius, hook block and lifting accessories, ground conditions and environmental limitations.

Heavy Lifting Applications and Project Suitability

The Liebherr LTM 11200-9.1 is designed for large-scale lifting operations where conventional medium-capacity mobile cranes cannot provide the required lifting capacity, boom length or working height.

One of its principal application areas is wind turbine installation, where heavy components must be raised to considerable heights. The crane’s 100-metre telescopic boom and optional lattice jib arrangements provide configurations suitable for positioning components on tall wind turbine structures.

The LTM 11200-9.1 is also applicable to power plant construction, petrochemical facility development, industrial equipment installation, heavy steel structure assembly and major infrastructure projects.

Its extensive range of boom and jib configurations allows the crane to be adapted to different lifting scenarios, including high-reach installation work, elevated equipment handling and heavy assembly tasks requiring extended horizontal outreach.

The nine-axle all-terrain carrier provides road mobility between project sites, while its modular boom and attachment systems allow the lifting configuration to be selected according to the project requirements.
