The 38 XXT truck-mounted concrete pump from Liebherr is in the 98-foot size class and features a four-part boom and Z folding.
Depending on customer needs, the pump can be mounted on a three- or four-axle chassis. The XXT outrigger system has a compact footprint and maximizes the reach of the distributor boom. It also transfers the boom loads along the shortest path to the contact areas of the support legs. No forces act on the vehicle frame, according to the company. The front and rear support legs swivel around the same axis on each side of the vehicle to save space.
The Powerbloc drive unit for the pump system integrates all hydraulic switching and measuring elements, eliminating hydraulic hoses and other parts.
