Liebherr LTM 1100-4.1

Crane Carrier Features:

• Frame and Outriggers: The LTM 1100-4.1 features a self-manufactured, weight-optimized frame made of high-tensile structural steel, ensuring robustness and durability. It comes equipped with a 4-point supporting system that includes hydraulically telescoping outriggers with automatic leveling for stability and precision in load handling.
• Engine and Transmission: The crane is powered by a 6-cylinder Liebherr D946 A7 diesel engine, outputting 350 kW (476 hp) at 1900 rpm, providing high torque and efficient performance. It integrates a ZF 12-speed gear box with an automatic control system that connects directly to the rear axle, allowing for smooth transmission and enhanced mobility.
• Axles and Suspension: The crane includes a hydro-pneumatic suspension system across all axles, with the second, third, and optional first axles driven and steerable. This system supports the crane’s capability in rough terrains, offering stability and ease of movement.

Crane Superstructure Capabilities:

• Crane Engine and Drive: A smaller 4-cylinder Liebherr engine powers the superstructure, delivering efficient operation with a maximum torque of 920 Nm at 1800 rpm. The drive is managed through a hydraulic system with a servo-controlled displacement pump, ensuring precise control over crane movements.
• Control System: The crane features an advanced electronic “Load Sensing” control system, which allows simultaneous operation of up to four working motions, significantly enhancing operational efficiency.
• Safety and Lifting Gear: The LTM 1100-4.1 is equipped with comprehensive safety devices including LICCON safe load indicators and various safety valves to prevent pipe bursts and ensure secure operations.

Additional Functionalities and Enhancements:

• Variable Steering and Drive Options: The crane offers a variable drive and steering concept, including the optional drive 8 x 8 configuration for enhanced traction and maneuverability. It features speed-dependent active rear-axle steering and multiple steering modes to adapt to various site conditions.
• Outrigger System: The crane’s outrigger system is designed for quick, convenient, and safe operations with a variable supporting basis, fully automatic leveling control, and illuminated control panels, ensuring efficient and safe crane setup.

The Liebherr LTM 1100-4.1 merges high mobility, advanced technology, and substantial lifting capacity in a compact design, making it suitable for a wide range of lifting tasks in both urban and rough environments. Its engineering is focused on providing high performance while ensuring user safety and comfort, making it a preferred choice in the 100-ton crane segment.
