The Liebherr 50 M5 XXT development focused on integrating new technologies and capabilities, lowering the overall weight and optimizing product dimensions.
An innovative highlight is the newly developed boom pedestal. Despite considerable weight reduction, the stability was increased. The slewing ring and drive are proprietary Liebherr components.
There are four different pump unit options for the 50 M5 XXT. This enables outputs of 138 m³ to 167 m³ per hour. Two of these variants are long-stroke versions with a conveyance stroke of 2,400 mm.
Depending on the chassis, the total length of the new Liebherr truck mounted concrete pump is around 12 m in the transport position. The new boom is particularly compact and has virtually no projection. This guarantees safe driving properties and exceptional handling on the construction site.
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 a huge benefit on construction sites with limited space.
Chassis from different manufacturers can be used for Liebherr’s truck mounted concrete pumps. A wide range of optional accessories and equipment are available for the 50 M5 XXT. Customers can 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 air cuff prevents concrete from running out when the pump unit is stopped.
