Liebherr’s smallest crane in the LR series offers advanced fuel efficiency

The LR 1100.1 is the smallest crawler crane in Liebherr's LR series. The crane fits into the 100 tonne category and is powered by an efficient 230 kW diesel engine. The steel structure provides ideal conditions to work on even the most challenging construction sites.

Fuel efficiency

The Eco-Silent Mode allows the engine speed to be reduced to a predefined level, minimizing overall diesel consumption and noise emission without affecting the performance of the machine.

The Automatic Engine Stop Control also offers a further economic and environmentally friendly solution. After checking certain system functions, the engine is switched off during longer work interruptions.

Familiar design

Even as the smallest crane in the LR series, the LR 1100.1 has the same technology and design as the rest of the LR cranes, including the same crane control and assistance systems already established.  

In addition to having the same feel as other LR cranes, select parts can be used across other LR models in the series, making ordering new parts easy.

Additional features 

• Self-assembly system - Independent and quick assembly of the crawler side frames, the carbody, and rear counterweights, the two hoist winches, as well as boom elements.
• Easy transport and quick set-up - Boom foot and crawlers remain on the crane during transportation.
• Gradient travel aid - Safely on the move on uneven terrain; the machine's control system automatically calculates its centre of gravity.
• Comfort - This includes a modern air-conditioning system with improved airflow, an optimized field of vision, and increased noise protection, as well as an orthopaedic operator's seat with integrated heating and cooling.
• Ground pressure visualization - The Ground Pressure Visualization calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant position.
• Consideration of wind speed - Both the measured wind speed and the actual crane configuration are taken into consideration when calculating the current hazardous situation for the crane. When the conditions become too dangerous, the system gives a warning.
• Moving with load on the hook - Driving is always carried out in "Safe Mode" with active Load Moment Limiter, and is dependent on the driving speed.
• Efficient drive unit - The crawler crane is driven by a high-performance and simultaneously economical Liebherr diesel engine. The emissions-optimized unit meets the latest exhaust emissions standards.
• Precise crane control - The control system developed by Liebherr includes all operating and control functions of the crane and permits very delicate and secure lifting. The load capacities are automatically calculated during operation. The calculation of the load moment indication is also effected steplessly or without interpolation. Optimal utilization of the machine is thus guaranteed.
