Liebherr has combined several of its technological developments to create the 36 XXT truck-mounted concrete pump.
After extensive testing, sales of the newly developed truck-mounted concrete pump 36 XXT from Liebherr have started.
The compact concrete pump, equipped with a 36-metre boom, combines the advantages of the new five-fold placing boom with the Powerbloc drive unit and the semi-closed oil circuit. The whole machine has also been given a new and attractive look.
During development, many pump operators requests were taken into account, such as ergonomic access steps, simplified accessibility and an expansion of the stowage and storage options.
As well, the machine includes an extremely compact superstructure without a boom overhang at the rear to ensure high manoeuvrability in confined areas. The machine is weight-optimized and, depending on the equipment, has a total weight of about 26 tonnes on three axles.
The XXT support ensures better stability. It comes into its own thanks to narrow supports, so confined spaces pose no problem.
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 allows for a great deal of flexibility and even-work when paving concrete. The boom has special slip properties that are especially beneficial when pouring concrete in buildings. The five-arm boom make it easy to reach a wide variety of positions on the construction site. The design and kinematics of the boom ensure low-vibration and even working during concrete placement.
The shape of the feeding hopper favours an even flow of concrete and good suction behaviour. The machine is also equipped with two separately driven agitators to push the concrete directly into the suction area, which works perfectly even with concrete types that are difficult to pump.
Powerbloc drive
The new 36 XXT is equipped with the newly developed Liebherr Powerbloc pump drive unit. It is characterized by the fact that all hydraulic switching and measuring elements are fully integrated. This eliminates the need for numerous hydraulic hoses and other components that were previously required. The feature makes the drive unit a speciality in the world of concrete pumps.Â
Hydraulic half close circuit
The new drive unit is combined 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 proven open and closed circuits on the current market without their respective disadvantages. Customers confirm the quiet and powerful operation of the pump unit.
