The 50 M5 XXT extends the range of truck-mounted concrete pumps available from Liebherr.
The multi-folding five-section boom features alternating pipework close to the boom for uniform movements over the construction site, the company says. The unit has a vertical reach of 161 feet and a horizontal reach of 146 feet. The slewing ring and drive are proprietary components, and Liebherr says the model is the “last German-engineered and –produced pump in the world.” There are four different pump unit options for the 50 M5 XXT that enable outputs of 180 cubic yards to 219 cubic yards per hour. Two of these variants are long-stroke versions with a conveyance stroke of 94 inches. Depending on the chassis, the total length of the truck-mounted concrete pump is around 39 feet in the transport position.
The patented XXT narrow support has front and rear support arms that 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. Chassis from different manufacturers can be used for Liebherr’s truck-mounted concrete pumps, and a wide range of optional accessories and equipment is available. 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.
