Jaine exhibited its HGY15 mobile concrete
placing boom – a compact machine
weighing 2.2 tonnes that is lifted into place
by a crane. It can rotate 360° and has a
horizontal reach of 15 m.
Sany had its SY5255GJB2E concrete truck
mixer on display, powered by a liquefied
natural gas engine that it claims could
save up to 30% on fuel costs.
Zoomlion’s stand included the ZlJ523GJBE

Chicago Pneumatic has introduced new mechanical,
electric or pneumatic pokers
Concrete accessories
Chicago Pneumatic meanwhile has focussed on productivity gains
with its latest concrete poker range. Customers can now choose
mechanical, electric or pneumatic pokers from the manufacturer
to best meet their specific application and concrete type.
Freshly poured concrete has air voids which must be removed
to increase its density and finished strength. Depending on the
concrete’s depth and slump, this can be achieved using a poker
or screed.
The company’s new VPM mechanical pokers are designed for
mid-sized sites using medium-to-high slump concrete. VPE
electric pokers, meanwhile, are aimed at medium-to-high slump
concrete, while the VPP pneumatic poker range is designed for
jobs of any size with low-to-high-slump concrete requiring high-
speed vibration.
In addition to pokers, the company’s new concrete product line
includes walk-behind screeds. The LBG 1200 hand-held screed
provides surface vibration only and is said to be suitable for slabs
of all types and concrete of all consistencies. Recommended
for smaller slabs and medium-to-low slump concrete, the LBG
800 bull float screed provides deeper vibration and single-step
levelling.
Further new products from Chicago Pneumatic include the
Contractor Stroyservice us using a Curb Fox 3000 to pave
curbs on a new by-pass road in Orjol, Russia. Initial paving
speeds average 3 to 4 m per minute. The total job includes
over 7000 m of curb to be placed by the spring of 2014.

new concrete floor saws.
Advances are also being made in other corners of the concrete
industry such as the reinforcement sector. Here, manufacturer
Bamtec claims its prefabricated rebar reinforcement elements
saved around 40% in laying time and also cut the amount of
steel used by around -7% on an office construction project in
Germany.
A total of 1,542 custom-made reinforcement elements will
be installed on the project, each tailored to match the slab
geometry of the building’s structure. According to Bamtec, about
