The Latest Generation Of Liebherr´S Lr 1300 Sx Crawler Crane

The brand new crawler cranes LR 1300 SX with derrick boom and displaceable suspended counterweight.

The LR 1300 SX, which belongs to the newest generation, has a lifting capacity of 661,387 lbs (300 t). For heavy loads, the crane can be fitted with a derrick boom in combination with an additional counterweight. The new suspended counterweight of the LR 1300 SX no longer has a fixed counterweight radius and instead can simply be hydraulically displaced.

The Liebherr assistance system “Boom Up-and-Down Aid” indicates the approach to the tipping border and automatically stops operation before the operator unintentionally enters an unsafe zone. It assists the operator in leaving the danger zone without having to activate the safety bypass switch. The new Liebherr LR 1300 SX is fitted with wind sensors on the main boom and jib. At wind speeds of (imperial mph) 10-16 m/s the operator can adjust the maximum lifting capacity through a simple selection on the control panel.

In addition to the influence of the wind, the ground load-bearing capacity and the monitoring of the ground pressure are also significant factors for the safe operation of the crane. The Ground Pressure Visualization of the new Liebherr crawler crane LR 1300 SX calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant position. 

Three different driving speeds can be selected by the crane operator. Driving is always carried out in “Safe Mode” with active Load Moment Limiter and is dependent on the driving speed. That means that the Liebherr crane control system, Litronic, automatically adjusts the lifting capacities to suit the driving speed, when driving with a load on the hook. 

The Liebherr LR 1300 SX is fitted with a new cabin concept, which focuses on increased operator comfort. This is achieved through a modern air-conditioning system with improved airflow, an optimized field of vision and reduced noise protection, as well as an ergonomic orthopaedic operator’s seat with integrated heating and cooling. 

The Crane Planner 2.0 is an intelligent software for planning demanding lifting applications. All work steps from picking up to setting down the load can be simulated on the PC or even in virtual 3D space. The feasibility of the entire project is checked in advance directly at the planning table. The advantages are obvious.
