M 42 now available as 5-arm boom

Still in October, Putzmeister AG will start delivery of their M 42 as a 5-arm boom to the customers. This compact concrete pump with five flexible and short boom segments has been introduced just recently to several customers from Europe. The response has been very positive.

Compact design and short boom segments are characteristical for the new Putzmeister “Roll-Z”-folder M 42-5.

The “Little One” in the 40-Meter-class shows its real size and flexibility where it counts most: on the construction site. Especially if only little space is available for set-up and operation.

This new M 42 5-arm is added by Putzmeister to the very successful M 42 4-arm model. That one has been introduced in 1997 and will remain in the program. To take the step from the 4-arm to the 5-arm, one additional joint is needed in the boom, which results in increased weight. Insofar it is surprising, that Putzmeister was able to keep the machines’ total weight well below 33 tons. The new 5-arm will complete the range of “Roll-Z”-folders in the 40-meter class.

As already introduced with the M 46 and M 47, the new M 42-5 is also conceived as a flexible “Roll-Z”-fold boom. The additional arm allows for higher flexibility when it comes to concrete placement in higher floors. The unfolding-height of this boom is only 8.6 meters. Especially practical for congested construction sites is the small outrigger footprint of 7.9 meters, both in front and rear. In OSS-mode, this can even be reduced to 5.1 meters (front) and 5.8 meters (rear).

Large working range, maximum flexibility and mininmal support width are typical advantages of the new truck mounted concrete pump M 42-5 with “Roll-Z”-fold boom design.

The short overall length of just 11.6 meters makes it easy to obtain road permissions, especially in France and Switzerland, where total length is limited to 12 meters. The short wheel base of only 5.5 meters (first front to first rear axle) is very useful when the machine needs to reach construction sites in small villages and narrow mountain streets. Also, the short boom does not create any rear overhang, so corners are not swept by the boom. Therefore this machine will be of special interest for concrete pump businesses in the Alps or other mid-range mountain areas.
