CONCRETE
Early involvement
The manufacturer said its technical proposal, including the
substantial volume of customised formwork, had been decisive
in it winning the order. Pilosio also emphasised rapid supply
times and co-ordinationwith the various organisations involved
in the project as crucial to its success.
Optimised equipment
Elsewhere intheconcretesector,manufacturerscontinuetorefine
their designs to make life easier for contractors. For example,
because it believes that equipment used on construction sites
should be mobile, light and convenient, Wacker Neuson said
it had optimised its exposed concrete surface external vibrator
AR 36 in terms of performance and overall size.
The result is the AR 26 external vibrator, which is about
2 kg lighter than its predecessor but with the same power
output, while still claiming to retain its flexibility. The
connection flange is compatible with the AR 36, so that the
fixing devices for in-situ casting formwork also fit the smaller
model.
Another area of application is concrete precast factories, said
Wacker Neuson, adding that where a few large external
vibrators were once used, several smaller models are often used
nowadays. It said this was one area of application where the
smaller AR 34 and AR 43 models from the new series
couldworkwell.
However, the manufacturer said continuity was a
high priority and the new external vibrators can be
operated on the same frequency inverters or converters as
the previous models. The bore patterns for attaching the
external vibrators have also been retained.
Controls, meanwhile, has developed a new setting
time meter – Vicamatic 2 – to boost the efficiency of
determining and monitoring the setting process for
cement, motar and gypsum. The new device features
both local and remote control mode, programmable
test cycles and an integrated graphic printer.
Test procedures are stored in the device’s memory
and immediately usable after fitting the correct needle,
weight andmould. Featuring a 109mm colour display,
Controls says the meter can automatically calculate initial and
final setting times at programmable
penetration depth limits.
Pumping andmixing
On the concrete pumping and mixing
side, meanwhile, Reed has developed
the new towable MixerPump Combo
machine. This is a mixer and pump
combined has designed specifically for
shotcrete contractorsneeding apowerful,
high pressure shotcrete pump and a fast,
robustmixer.
The 15 m³/hr pump and 1 tonne
M2200 Mixer are both powered by a
119 kW Cummins engine. The hopper
has a capacity of 16 ft³ (0.453m

) with
the addition of the optional hopper
extension. Reed said the mixer can

Liebherr installed a Betomat V 1010mixing tower for Alfons
Greten in Essen, Germany – the largest of itsmixing plants,
and one that had only been installed once previously.
