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 desired, making it perfectly suited for all types of concrete pours on small construction sites.

The 4Z27 is indispensable on sites with limited space: this pump not only delivers powerful performance, but also excels with its compact design. It’s ideal for work in densely built environments where space is scarce. Thanks to its flexibility, this machine is perfectly deployable in any urban context.

In combination with a 2-axle truck, this concrete pump has a low weight and offers optimal maneuverability. Additionally, the boom unfolds quickly, which is of great value in situations where time is critical.

The 4Z27 features a 4-section boom with a fully Z-folding system. The boom is operated by a 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, results in optimal stability during concrete pumping operations.

The pump unit enables performance of up to 117 m³ of concrete per hour. The open-loop hydraulic system, combined with an accumulator-assisted S-valve, guarantees optimal output. A specially shaped hopper minimizes the cleaning effort required for the pump unit.

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