30-Second Takeaway
Liebherr-Werk Nenzing has strengthened its heavy lift portfolio with the introduction of the LR 1400 SX, now the largest crawler crane at the site. Succeeding the LR 1300, the 400-tonne-class crane combines exceptional boom reach, advanced self-rigging technology, and industry-leading ground pressure reduction. Designed for efficiency, safety, and operator comfort, the LR 1400 SX highlights Liebherr’s continued innovation in crawler crane engineering for demanding infrastructure, industrial, and energy projects.
Liebherr LR 1400 SX: Setting a New Benchmark for Multipurpose Crawler Cranes
Liebherr-Werk Nenzing has taken a major step forward in crawler crane development with the introduction of the LR 1400 SX, now the largest and most advanced crawler crane operating at the Nenzing facility. Designed as a true multipurpose heavy lift solution, the LR 1400 SX responds directly to evolving market demands for greater lifting capacity, enhanced safety, simplified transport, and maximum on-site flexibility.
With lifting capacities of up to 400 tonnes (441 USt), the LR 1400 SX expands Liebherr’s crawler crane portfolio into a new performance class, bridging the gap between compact site cranes and larger heavy-lift machines, while retaining exceptional mobility and efficiency.
Engineered for Mobility and Efficient Transport
Despite its impressive lifting performance, the LR 1400 SX has been engineered with transport efficiency firmly in mind. With a compact transport weight of just 46 tonnes (50.7 USt), the complete crane can be moved easily between jobsites, significantly reducing logistics complexity and cost.
Key transport advantages include:
Platforms and railings remain attached to the uppercarriage during transport and only need to be folded down
No auxiliary crane required for assembly or disassembly thanks to the integrated self-assembly system
Boom sections, crawler frames, hoist winches, and carbody counterweights can all be handled by the crane itself
A standout feature is the crane’s ability to hydraulically lift, lower, and secure its own rear counterweight, weighing up to 150 tonnes (165.3 USt), without external assistance. The modular rear counterweight system allows the crane to be configured with 5- or 10-tonne slabs, enabling operators to tailor the setup precisely to project requirements.
Designed for Tight Jobsites and Maximum Maneuverability
The LR 1400 SX excels where space is restricted. Its four independent crawler drives provide exceptional maneuverability on congested sites, while adjustable track widths simplify access on narrow roads and confined project areas.
These features make the crane particularly well suited to:
Wind farms with limited access roads
Urban infrastructure projects
Industrial facilities with tight laydown areas
Bridge, tunnel, and stadium construction
Advanced Safety Through Intelligent Assistance Systems
Safety was a core focus throughout the LR 1400 SX’s development, resulting in a comprehensive suite of intelligent assistance systems designed to support operators during both lifting and travel operations.
Gradient Travel Aid
This system ensures safe travel on slopes by continuously calculating the crane’s center of gravity. The operator receives real-time feedback on:
Actual vs. permissible gradient
Crane center of gravity position
If the crane approaches a critical limit, the system warns the operator and can prompt adjustments including modifying the boom angle to keep the machine within a safe operating zone.
Ground Pressure Visualization
The LR 1400 SX calculates ground bearing pressure in real time, displaying this data directly in the operator’s cab. The system compares actual pressure against defined safety limits for the crane’s position, ensuring the operator always knows whether the crane is approaching critical ground conditions.
For sensitive terrain, ground pressure reduction plates can be deployed hydraulically to significantly increase the crane’s footprint. When activated, these plates can reduce ground pressure by more than 50%, a major advantage when:
Working on soft soil
Lifting long boom systems from ground level
Operating in environmentally sensitive areas
Boom Up-and-Down Assistant
During boom erection and dismantling, this assistant:
Monitors proximity to the tipping boundary
Automatically stops operations before unsafe conditions occur
Coordinates controlled folding of the luffing jib at the push of a button
The operator no longer needs to manage multiple winches independently. Instead, the system selects the safest method and controls the movement via a single joystick, reducing complexity and operator workload.
Flexible Operation with Radio Remote Control
The LR 1400 SX offers radio remote control operation, giving operators greater flexibility and improved site visibility. Operating the crane from outside the cab allows:
Better line of sight to the load
Reduced blind spots
Enhanced safety during complex lifts
In many applications, this capability eliminates the need for a second person to provide hand signals, streamlining operations and improving communication.
A True Multipurpose Crane for Diverse Applications
Designed around customer feedback, the LR 1400 SX supports easy boom configuration changes and remains compatible with fixed and luffing jibs from the LR 1300, offering existing Liebherr customers added flexibility and value.
As a multipurpose crawler crane, the LR 1400 SX is suited for a wide range of projects, including:
Wind energy installation and maintenance
Infrastructure projects such as bridges and tunnels
Industrial construction and factory assembly
High-rise building construction
Precast concrete and steel erection
Barge and floating crane applications
