ELBA-WERK Maschinen-Gesellschaft will put the spotlight on some of its latest advanced machines for mixing and pumping concrete at bauma 2010. Making their debut at the show will be its planetary counterflow mixer EMPG 1000 and the large-boom pump EM 51/57.

The German company combines quality, performance and economic efficiency to produce high-standard construction machines for concrete.
Elaborating on the machines, a spokesman for the company says: “Planetary counterflow mixers are mainly applied in block-making. The EMPG 1000 distinguishes itself by a rotor which turns around the vertical centre axis and, depending on the mixer size, is fitted with one to three rotating mixing stars or agitators.
“The new gear of the EMPG 1000 enables a variety of ratios to be set between rotor and mixer, thereby allowing within one mixing cycle a range of variation of mixing kinematics unknown so far.
It allows the energy input and/or the speed ratio to be adjusted to the respective mix. Additional advantages are the targeted energy input in the mixer and, thus, the possibility of minimising wear.”
Meanwhile, the large-boom pump EM 51/57 combines the proven philosophy of the Elba concrete pumps with innovations as regards boom folding, control, hydraulics, and application flexibility, according to the spokesman.
“The boom specially designed for this pump reaches heights of 57 m and, what’s more, offers high flexibility in all fields of application. It features up to seven joints for positioning the outlet hose on site in a slewing range of 360 degrees, independent of the boom position, allowing its use in almost every site situation. A new type ‘K’ stabiliser system enhances its flexibility. Furthermore, the folding system allows excellent access for cleaning and maintenance,” he says.
For over 60 years, Elba has developed, fabricated and sold machines and systems to produce and transport concrete. Elba’s extensive range caters for a wide range of requirements in terms of capacity and application.
The single-shaft and twin-shaft mixers distinguish themselves by the double-spiral system and enable the material to be mixed gently and efficiently.
Elba’s product range includes single-shaft and twin-shaft compulsory mixers, planetary counterflow mixers, stationary and mobile concrete mixing plants, linear bins, control systems for mixing plants, precast factories and concrete pumps, truck-mounted concrete pumps, stationary concrete pumps and manually-operated and fully automatic scrapers.
