Truck-mounted concrete pump 37m in length with innovative XXT-narrow support
The Liebherr truck-mounted concrete pump 37 Z4 XXT features a four-section, 37 meter distributor boom in Z-fold design. Due to its high torsional resistance, the pump exhibits low-vibration boom movements on the building site. The concrete line is configured close to the boom on the left and right-hand sides, guaranteeing a balanced weight ditribution.
The patented XXT-narrow support from Liebherr is extremely sturdy and torsionally-resistant. All four outriggers are pivot-mounted, allowing maximum flexibility and a particularly extensive working range of the distributor boom with narrow supports. This can prove to be a decisive advantage on building sites with restricted access.
Functioning of the pump unit is especially smooth. High-performance pump units featuring maximum flow rates of 125 m³/h, 138 m³/h and 163 m³/h can be fitted in accordance with individual customer requirements. These powerful Liebherr pump units are renowned for their distinctive smooth running.
As well as the Z-fold boom design, the truck-mounted concrete pump featuring a reach of 37m is also available with a rolled fold boom design. Liebherr also offer the XXH- and ST-supports as an alternative to the XXT-narrow support.

The compact designed truck mounted concrete pump 37 Z4 XXT has good driving characteristics
The pump is ready for operation in a short time and the flexible XXT outrigger system guarantees a high stability
The forces are transferred direct from the boom to the outrigger, the chassis won’t be strained
The new Liebherr design can be also realised in customer’s colouring
Discharge hopper and pump mechanics have no problems with hard concrete formulas.
Consistant motions at concrete pumping are the result of the rugged boom structure
Up to 70 % more working range is possible due to the patent protected XXT outrigger system, an important advantage is the concrete pumping across the driving cab
