The Liebherr 38Z4 XXT truck-mounted concrete pump offers a 4-part distribution boom in a Z-fold configuration.
A member of the 30-meter class, the model comes standard with XXT-outriggers and an XXA stability assistance system. The pivoting XXT support is very flexible when supporting in tight spaces, Liebherr says, and the new XXA stability assistance system allows the concrete pump to be electronically monitored.
The concrete pump is also equipped with the company’s latest drive unit, called “Powerbloc.” This unit does not require a separate control block, as all hydraulic switching and measuring elements are integrated.
A modern radio remote control allows precise boom movement. The clear color display shows operators all important parameters.
The design and kinematics of the boom ensure low vibration while pumping. Separately driven agitators push the concrete directly into the suction area, which works perfectly even with concrete types that are difficult to pump, according to the company.
