Putzmeister to launch even more compact and versatile M24 and M28

By MEq October 27, 2021 14:03

The 20 m class by Putzmeister is entering the next stage. Right from the beginning, customers – from owners to machine operators and service technicians – were on board during the development process. They discussed ideas with Putzmeister experts in meetings and workshops. The result speaks for itself: The new truck-mounted concrete pump models M24 and M28 impress with more versatility, infinitely variable support, more compact size, and a great deal of storage space. Much has been optimized in terms of ergonomics and safety too.

The construction machinery manufacturer from Aichtal clearly did everything right by bringing in customers at the early stages, meaning their needs could be taken into account right from the beginning. The new M24 and M28 machines bring together both innovative and tried-and-tested features. The models are already at the top of everyone’s wish lists simply because they are easier and more efficient for machine operators to handle, while owners are enthusiastic about the possible uses and corresponding profitability.

Limitless versatility, whether in urban areas or low buildings
The new compact 20 m class provides many possibilities: The new machines have been developed and equipped for special applications in particular. This means that they are in their element in inner-city areas, as well as low buildings, tunnels, or when concreting bridges, or for hose applications.

As robust as always, while more compact and maneuverable
What is behind the compact dimensions and new maneuverability at overall increased stability is the new TRC design (Trapezium Compact), which is a further development of Putzmeister’s proven TRD system. Thanks to the double telescopic support legs, the installation space required is reduced to a minimum – saving up to 600 mm of space in comparison with TRD.

At least 10 percent more – increased storage space that makes all the difference
The 4.3 m long, free and continuous flatbed (at standard MB dimension 5600) combined with the modular storage concept offers improved accessibility and, most importantly, a great deal more space than the previous models. This means more space for containers, shelves, or storage compartments for hoses, pipes, couplings, and other accessories. You can transport more than 200 m of hoses and pipes depending on the machine configuration.

Ergonomics and safety are top priority
A high level of safety already comes as standard at Putzmeister, for example with a continuous flatbed, handrails, a safety cut-out on the hopper, and many more features. The continuous flatbed, as well as increased usable areas, minimize the risk of tripping, and, together with the new all-round lighting, create ergonomic working conditions. As a result, the machine can be set up well even in bad lighting.

Saving space is key – whether with infinitely variable support or flexible boom movements
The models in the 20 m class are impressive here too. Thanks to the new TRC support, they can be set up in any number of different support positions – infinitely variable, from no support to full support! The machine operator adjusts the machine depending on the space available on the construction site – the automated machine does the rest using live calculations.

The same applies for booms, where the slip characteristics, in addition to the horizontal reach, decide where the machines can be used. The Z roll-and-fold system of the M24 undoubtedly offers outstanding slip characteristics combined with a low unfolding height in even the tightest of spaces. In this respect, it is predestined for use in low buildings, under bridges and in tunnels, etc. An entirely new feature is the “Hall-master” function: The boom is folded in front of the driver’s cab, moved into a building or tunnel, and can then be unfolded there with no interference from the driver’s cab thanks to the new arm kinematics. By contrast, the user-friendly and compact Z fold system of the M28 primarily saves time, since it is ready for use in no time.

High pumping pressure for efficient operation
Putzmeister’s powerful, economic core pumps with outputs of up to 160 m3/h and a pressure of 85 bar are almost legendary. The iLS core pumps and the Putzmeister iONTRON hybrid drive, unique in the world, prove to be even more efficient, as well as environmentally friendly. Both are now available for the 20 m machines.

Operating with Ergonic 3 is easy – clear, fast, and safe
What’s more, importance has been placed on retaining familiarity on the control units and integrating innovations in such a way that they make day-to-day operation easier right from the start. Putzmeister has added some future-oriented functions. Operation with Ergonic 3 is pleasingly intuitive and practical so that even challenging concreting in low buildings is easy.
