04/11/2016 The new Liebherr 50 M5 XXT truck mounted concrete pump: Compact on the road, wide coverage on the construction site

  • Weight-optimised
  • Slewing drive and slewing ring from Liebherr
  • Patented XXT support

At the Bauma 2016, Liebherr is presenting the new 50 M5 XXT truck mounted concrete pump to the general public for the first time. The vehicle, positioned in the 50-m class, includes many new innovations. The development focused in particular on optimising the unladen weight and the dimensions.

The new truck mounted concrete pump by Liebherr provides better cost efficiency and many innovations for increased customer benefits.

The new 50 M5 XXT extends the range of truck mounted concrete pumps from Liebherr. The boom with five-way multi folding is extremely easy to operate with its perfect kinematics. The alternating pipework close to the boom ensures uniform movements over the construction site. With a vertical reach of 49.1m and a horizontal reach of 44.4m, the compactly constructed truck mounted concrete pump provides impressive working ranges.

An innovative highlight is the newly developed boom pedestal. Despite considerable weight reduction, the stability was increased even further. A crucial role is played here by the proprietary components, such as the slewing ring and the slewing drive, for example. The truck mounted concrete pump benefits here from decades of Liebherr's know-how in the development and manufacture of these components for other construction machinery.

The 50 M5 XXT is optionally offered with four different pump units. This enables outputs of 138m³ to 167m³ per hour. Two of these variants are long-stroke versions with a conveyance stroke of 2,400mm, which are particularly smooth and efficient.

Compact construction, low unladen weight

Depending on the chassis, the total length of the new Liebherr truck mounted concrete pump is around 12m in the transport position. The new boom is particularly compact and has virtually no projection. This guarantees safe driving properties and good handling on the construction site.

In Europe, the Liebherr 50 M5 XXT is mounted on standard, five-axle chassis (10x4). The unladen weight is significantly below 40 tonnes. There is therefore sufficient spare weight for comprehensive accessories. For markets without an axle weight restriction, the pump can also be mounted on a four-axle chassis (8x4). In this variant, the unladen weight is below 38 tonnes.

Innovative XXT outrigger system

Liebherr is the only manufacturer to supply the patented XXT narrow support, which is extremely stable and warp-resistant. The front and rear support arms are affixed directly to the distributor boom pedestal, which directs the forces from the boom into the supports directly without deviations. All four support arms are pivotable. This enables high flexibility and an extremely wide working range for distributor boom on narrow supports. This is of particular benefit on construction sites with limited access.

Chassis from different manufacturers can be used for Liebherr’s truck mounted concrete pumps. A wide range of optional accessories and equipment is available for the 50 M5 XXT. Customers can therefore choose from additional storage compartments, a modular water tank or additional steps on the left hand side. A high pressure cleaner makes cleaning easier and a pneumatic hose end pinch valve prevents concrete running when changing over the boom.
