The 27-meter concrete pump stands for simplicity, efficiency, and versatility.
Thanks to its smart design, this machine effortlessly integrates a wide range of accessories as needed, making it perfectly suited for any type of concrete pour on small construction sites.

The 4Z27 is indispensable on sites with limited space: this pump not only delivers powerful performance but also stands out for its compact design. Ideal for work in densely built environments where space is limited. Thanks to its flexibility, this machine is perfectly suited for use in any urban setting.

In combination with a 3-axle truck, this concrete pump offers a low overall weight and optimal maneuverability. Additionally, the boom opens quickly — a key advantage in time-sensitive situations.

The 4Z27 features a 4-section boom with a complete Z-folding system. The boom is operated via radio remote control from the AUTEC® brand, combined with a proportional valve block. The design of the boom, in combination with an accumulator-driven pump group, ensures maximum stability during concrete pumping operations.

The pump unit enables output of up to 117 m³ of concrete per hour. The open-loop hydraulic system, combined with an accumulator-assisted S-valve, ensures optimal performance. The specially shaped hopper reduces cleaning of the pump unit to a minimum.

The Bonneux Xanjer 4Z27 guarantees maximum stability thanks to hydraulically operated outriggers. The front outriggers deploy in an X-pattern, while the rear outriggers extend horizontally. All sliding components are supported by ball bearings, and the combination with the truck’s automatic engine speed control ensures smooth and efficient stabilization of the machine.
