Putzmeister launches big and small
By Murray Pollok07 April 2010
Expect a big showing from one of the giants of German construction equipment manufacturing, Putzmeister, with new concrete pumps of all shapes and sizes as well as innovations in some of its less well known product ranges, like high pressure washers.
In the truck mounted pump sector, the M 49-5 placing boom is a new model on a four-axle chassis. Another new placing the boom, the M 46-5, is a semi-trailer model with five axles developed in particular for India. This gives the user greater flexibility in choosing the tractor unit.
Offering the same flexibility of tractor choice is the new Telebelt 130, a mobile telescopic belt conveyor mounted for the first time on a semi-trailer.
Bauma will see the European launch of the MX 30 placing booms for high-rise concrete placement. This can be mounted on lattice towers or tubular columns, such as the new PM RS 850 tubular column, which also gets its launch at Bauma.
For pre-cast concrete works, Putzmeister has designed the new RV 12 Lift rotary concrete distributor, although it can also be used for conventional floor concreting jobs. The unit has two arms with articulating joints, with the outer arm capable of being lifted to a height of 4 m.
Also on show will be the prototype of a concrete wet spray system, the SPM 4207, which will replace the SPM 407. This is designed primarily for tunnels with small cross sections, with a working width of 8 m and spraying capacity of 20 m3/hr.
Putzmeister also makes compact concreting tools, of course, and new at Bauma will be the Mixokret M 700 E electric screed, the smallest and lightest Mixokret yet. This model doesn't have an integrated compressor. Look out also for a new version of the Mixokret M 740 - no details of the changes, but Putzmeister promises a real technical innovation.
The new P 718 concrete pump is designed for fine concrete, typically for liquid screed but also capable of pumping concrete with grain sizes up to 32 mm. Another innovation is the SP 11 BUR plastering machine, the new top of the range model in the Beliso worm pump range with a new 4 cylinder engine.
In the high pressure cleaning range, Putzmeister launches the Dynajet 800 me, a compact electric trolley unit with 800 bar delivery pressure, making it "the world's most powerful high-pressure cleaner in its class." The company will also show improvements to its diesel drive Dynajet 500 md and the Dynajet UHP 170.
