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.
