The pivoting XXT support is particularly versatile when supporting in tight spaces. Nonetheless, even on the side where there is little space, the front support can still be extended in front of the driver's cab thanks to the swivel option. This adds the entire working area in front of the driver's cab. Even with narrow support on both sides, work is possible across the driver’s cab.
Thanks to LiDriveIn, the 31 XXT can enter a building in normal operation with the arm package folded in front of the cab. This means that the machine can enter a building through an only 4 m high opening. In the hall, the machine operator can easily unfold the distribution boom in front of the cab thanks to the short arm segments and the low unfolding height of just 5.4 m. Less effort, more safety and more efficiency.
The Powerbloc is characterized by high performance and smooth running. The latest drive unit for concrete pumps does not require a separate control block, as all hydraulic switching and measuring elements are integrated.
Thanks to the new XXA stability assistance system, partial support areas are made possible and electronically monitored. Thus, the new stability offers even more application possibilities due to the multitude of additional support options and at the same time ensures safe working in every situation.
The highly efficient semi-closed oil circuit guarantees that all drives are permanently supplied with reliable and powerful hydraulic power. The new Liebherr own system combines the advantages of the proven open and closed hydraulic systems currently on the market, without their disadvantages.
The hose and piping storage systems for our truck mounted concrete pumps allow the best possible adaptation to customer requirements and ensures convenient and safe storage.
