In-house development and optimisation of the mast were the main aspects of this revision. Various design features have been introduced to simplify the replacement of worn parts for more efficient servicing. The new 47 m, 5-section multi-fold distributor boom is extremely torsionally-resistant ensuring that vibrations are reduced to an absolute minimum when unfolding the boom on the building site. To ensure a balanced weight distribution, the concrete pipeline is configured close to the boom on both the left and right hand side. A minimal pressure loss over the entire length of the distributor boom is guaranteed by the pipe bend in the concrete pipeline featuring a radius of 275 mm. Moreover, the pipe bends used are predominantly of the same type minimising required storage of various worn parts. The compact boom package, with no overhang at the rear of the vehicle's chassis, in correlation with the truck-mounted concrete pump design lends the vehicle a neat and streamlined appearance.

Patent protected and the only one of its kind available on the market, Liebherr's XXT narrow support is low torsion and extremely robust. The front and rear outriggers are secured directly onto the boom pedestal of the distributor boom, ensuring that all forces bypass the boom completely and are channelled directly into the outriggers. Four pivoting outriggers guarantee maximum flexibility and an extremely wide swing range of the distributor boom when supporting a narrow configuration. This can prove crucial when working on building sites with restricted access.

The truck-mounted concrete pump 47 M5 XXT can be equipped with two high-pressure pump units featuring varying performance outputs. The pump unit 140HL conveys up to 140 cu m/hr concrete, whereas the 160HL is capable of up to 160 cu m/hr concrete.

Depending on different customer requirements, the truck-mounted concrete pump 47 M5 XXT can be arranged on a four-axle chassis for selected manufacturers, like MAN or Mercedes.

A wide range of optional accessories and equipment is available for the 47 M5 XXT. This allows the customer to opt for extra storage compartments or a second diesel tank or an additional access point on the left-hand side of the vehicle. A magnetic rotating flash provides added safety and a pneumatic pinch valve on the end hose prevents concrete spillage when repositioning the boom. Liebherr's rugged and durable concrete pumps are developed and produced in Germany with components of quality from renowned manufacturers.
