M28-4
The multi-talent for all applications
This compact machine is perfect for anyone looking for mobile, manoeuvrable and flexible concrete pumping. Despite its low height, it can master significant challenges: Tight or restricted set-up spaces, for example in inner-city areas and construction sites requiring good slip characteristics, or when building bridges.
The M28-4 Z boom has also become even more flexible: The A hinge now has an angle of up to 100°, meaning the arm can be overextended to facilitate manoeuvring, for example inside buildings.
