Liebherr’s 36 XXT truck-mounted concrete pump combines the advantages of the five-fold placing boom with the Powerbloc drive unit and the semi-closed oil circuit. This machine is weight-optimised and, depending on the equipment, has a total weight of around 26 t on three axles.
A compact superstructure without a boom overhang at the rear enables high manoeuvrability in confined areas, and the XXT support ensures better stability. The modern radio remote control allows sensitive boom movements, while the clear colour display shows the operator all the important parameters.
The five-section boom provides maximum flexibility on the construction site, and makes it easy for the operator to reach a wide variety of positions. The design and kinematics of the boom ensure low-vibration and even working during concrete placement.
The boom features special slip properties, especially when concreting in buildings. The shape of the feeding hopper favours an even flow of concrete and good suction behaviour. Two separately-driven agitators push the concrete directly into the suction area, which works well even with concrete types that are difficult to pump.
A key highlight of the 36 XXT is the newly developed ‘Powerbloc’ pump drive unit from Liebherr. The system is characterised by its robustness, high performance and smooth running, with all hydraulic switching and measuring elements fully integrated. This eliminates the need for numerous hydraulic hoses and other components that were previously required.
The drive unit is equipped with the highly efficient, hydraulic half-closed circuit, which supplies all drives powerfully and reliably with hydraulic power. As a result, the oil volume could be significantly reduced. Liebherr’s new proprietary system combines the advantages of the open- and closed-circuits on the current market without their respective disadvantages.
A range of accessories are also available, such as ultra-modern LED lighting concepts for problem-free working in the dark, various storage boxes for materials and tools, as well as shelves for extension hoses.
The 36 XXT truck-mounted concrete pump was recently showcased to the media during the Liebherr international trade press tour 2024, which took place in late October in Germany.
