The Liebherr LTR 1150 telescopic crawler crane was introduced to the public at the Intermat exhibition in Paris on April 24, 2023. This crane represents a notable advancement in Liebherr’s telescopic crawler range, sitting between the LTR 1100 and the LTR 1220, and is designed to meet the growing demands for higher capacity and more efficient transport in heavy lifting and construction operations.
Capacity and Performance
The LTR 1150 boasts a maximum lifting capacity of 150 tonnes, which is a 50% increase over the 100-tonne LTR 1100. It is equipped with a 52-metre telescopic boom and can achieve hoisting heights up to 83 metres with its various jib and boom extensions. The crane’s innovative VarioBase system allows it to automatically adjust the load capacity based on the crane’s track width and the angle of rotation, enhancing operational safety and efficiency.
Transportation and Setup
Designed with logistics in mind, the LTR 1150 maintains a transport-friendly profile. It has a total weight of 60 tonnes with the undercarriage attached, and a width of 3.5 metres. For more compact transportation, the undercarriage can be removed, reducing the weight to 38 tonnes and narrowing the width to 3 metres. These features ensure that the crane can be easily and economically transported to and from sites, similar to its smaller counterpart, the LTR 1100.
Technological Advancements
A standout feature of the LTR 1150 is the introduction of the Liebherr VarioBase system. This system is a first for the telescopic crawler crane series and offers real-time optimization of load capacities. It adjusts the crane’s operational parameters based on the sensor readings of track width and rotation angle, allowing for safer and more efficient lifting operations, particularly when handling heavy components over the crane’s tracks.
Applications in Wind Turbine Assembly
The LTR 1150 is not only powerful but also versatile. It is particularly suited for auxiliary tasks in the assembly of wind turbines, a growing sector in renewable energy. The crane can assemble crawler cranes up to the 1,000-tonne class and handle wind turbine components like nacelles and hubs, which typically weigh over 60 tonnes. This capability makes it an invaluable asset on construction sites for renewable energy projects.
The Liebherr LTR 1150 sets a new standard in the telescopic crawler crane market with its increased capacity, innovative technology, and ease of transport. Its debut at the Intermat exhibition highlights Liebherr’s commitment to advancing crane technology and meeting the diverse needs of modern construction and industrial projects.
