Schwing-Stetter announces current world record in vertical pumping and presents many innovations

SCHWING again sets standards at the 2010 bauma with a new world record in vertical pumping: 715 m – with an SP 4000, i.e. a stationary medium-size concrete pump that was successfully employed at the Parbati Hydroelectric Project in India. As the world’s leading systems company for concrete construction machines, SCHWING-Stetter again impresses visitors at this year’s bauma with numerous new and furtherdevelopments in all product areas of ready-mix concrete technology: concrete mixingequipment, truck mixers and concrete pumps as well as placing booms.

The corporate group documents for the first time the environmental and climate protection activities it has been carrying out for decades in some cases. Like the trimodal transportation system – rail, road and inland shipping. The motto gogreen consciously has a challenging undertone intended to motivate people both within and outside the company to get involved. SCHWING GmbH has taken considerable measures to reduce CO2 emissions by 100 tons annually, for instance. In addition, in-house communications are increasingly in paperless form, parts shipment extensively takes place using returnable packaging and also compostable plastic film.

The high-quality machine paints have been completely changed over to a water-soluble base, thus reducing solvent output by 30% while providing increased covering power at the same time. SCHWING-Stetter is already in the process of implementing these and further measures, others will follow. As is generally known, SCHWING offers exceptionally energy-efficient, i.e. fuel-saving, as well as low-wear machines to other companies. This means the gogreen initiative is also supported and practiced by the customers – combined with the pleasant effect of saving operating costs and expenses due to wear in this way. Speaking at the occasion, Mr. Gerhard Schwing, Chairman, SCHWING Stetter Gmbh, said, “Held once in three years, the BAUMA fair is one of the most important platforms for construction equipment players globally, giving us an opportunity to showcase the pioneering initiatives that we undertake in our products. This year, all our efforts revolve around the theme “Go Green”, under which we are implementing various measures to create a more sustainable environment.

Towards this, we have also incorporated some unique green features in the products. Our clients look for methods that will enable them to optimize their investments more effectively and our products have been designed, keeping this in mind. We are sure that the products will be received well by our customers.”

SCHWING Product Innovations:
bauma premiere 1: The new S 20 concrete-mounted pump is a high-performance, extremely maneuverable and flexible machine, complementing the City class of its product range. The S 20 with a four-section placing boom and extremely small outrigger spread of only 3.85 m is ideal for operations in narrow streets or next to flowing traffic. Because of its low unfolding height, also only 3.85 m, it is predestined for tunnel construction and indoor buildingprojects. Thanks to a large selection of accessories and optional equipment, every customer can configure an S 20 customized to his needs, from simply the hose pump all the way to the universal truck-mounted concrete pump with up to 260 meters of additional hose lines on board.

bauma premiere 2: SCHWING again demonstrates high performance with its new S 43 SX long-boom pump, including a five-section placing boom with Roll-Z folding. This boom concepthas already proven its effectiveness in recent years in the S 36 SX and S 52 SX – both on view at this year’s bauma – on the basis of the excellent threading characteristics of the special boom kinematics. The combination of a five-section placing boom with Z-folding, space-saving curved outriggers in connection with a consistently lightweight design makes this machine the new measure of all things in its class.

bauma premiere 3 is the new SCHWING stationary SP 2880 concrete pump, which was specially designed for large European-type construction sites. Based on the forward-lookingdesign of the modern plastic casing, it is entirely in line with the gogreen initiative since thesignificant weight savings lead to substantially lower fuel consumption during transport. Speaking of gogreen, SCHWING has done away with installation of an energy-consumingchangeover block for the changeover from the piston to the rod side.
In the SP 2880 the hydraulic hoses can be very simply detached by hand using drip-free quick-action couplings and reconnected – no dripping oil, no waste of fuel due to changeover block heating – problems can be avoided so easily. SCHWING rounds off the green concept in this machine with the SP 2880’s noise abatement system.
The new control with display, which provides all current operating data like engine speed, hydraulic pressure and stroke, is impressive. The control system can be enhanced with a bluetooth remote control. The modular structure, including a vertically adjustable hitch, permits use of two different axles – a construction site axle and an optional road axle for towing speeds of up to 80 km/h.

bauma premiere 4: In addition to the modern product line of SCHWING separate placing booms, the company now presents the new separate SPB 32 placing boom at the bauma. This flexible four-section placing boom is a genuine wonder in tight spaces thanks to its Roll and Fold capability. Thanks to a lightweight design and future-oriented tubular columntechnology, it can operate on a pedestal without counterweight up to a stand-alone height of 20 meters. The simple assembly and many other details make this product line especiallyattractive for users and site managers.

Stetter Product Innovations:
The four product lines of Stetter’s truck mixers are available in C or C+ version with ratedvolumes from 6 to 15 m³. bauma premiere 5: Stetter now extends its TRAILER LINE to include the weight-optimized tractor-trailer unit AM 10 FHAC – LIGHT LINE, which offers anadditional load of up to 10 m³ of concrete (at 2,400 kg/m³) in the combination 2-axle truck-tractor and 2-axle semitrailer (permissible total weight 38 t). The truck mixer and tractor-trailer chassis form a compact, maneuverable unit. The low curb weight combined with the use of hardened materials in the mixing drum makes for a high payload and a long service life at the same time.
The intelligent SMART-Control truck mixer control system now offers even more operating comfort. The system selects the most economical operating point automatically by means ofdrum speed specification for the filling and emptying process, including the characteristic map of the diesel engine. As a rule, this optimum point is in the lower engine speed range. In driving operation the current diesel engine speed is recorded and taken into account as an influencing parameter for rapid control and maintenance of a constant drum speed (constant drum speed drive). The results are fuel savings, a significant reduction in wear due to 50% fewer drum revolutions during road travel and lower noise emissions.
In the now extended SMART-Control the mixing drum speed is intuitively set via a continuously variable adjustment process by means of ergonomic single-lever control - bauma premiere 6. A memory function (start-stop of mixing drum while maintaining the preset drum speed) is integrated into the control lever. In the extended version, too, the drum speed, operating hours, maintenance intervals, etc. are shown in the terminal’s two-line display. User-friendly functions, such as an automatic remixing function, query for operating data and personalization of operating data, can be seen on the terminal without additional hardware. In the variant with cab control all mixing drum functions as well as two constant speed drive settings can be controlled from the cab.
Stetter has extended the mobile mixing units that have been successfully marketed for years by adding two model ranges. The top performance segment now includes the M 2,5 mobile unit with a production capacity of 114 m³ of compacted fresh concrete per hour. Thealready existing M 2,25 has been optimized through diverse modifications and its capacity has been increased from 101 to 108 m³ of compacted fresh concrete per hour. The lower range of the segment has been extended to include the M 1,25 – bauma premiere 7. This mobile unit, also equipped with a Stetter DW 1,25 twin-shaft mixer, achieves a capacity of 70 m³ of compacted fresh concrete per hour and meets the requirements for concrete having top mixingquality for medium volume needs.
The modular system of horizontal concrete mixing units was adapted to market requirements and is now also available in the complete model range from HN 1,5 to H 6, with a hot-dip galvanized design. The horizontal mixing units were expanded to include the HN 2,5 (bauma premiere 8) and HN 3,5 models. Both units are equipped with the proven Stetter twin-shaft mixers. The HN 2,5 attains a capacity of 111 m³ and the HN 3,5 132 m³ of compacted fresh concrete per hour. Particularly in European markets, truck mixers are primarily loaded with 7.5 m³ with a total weight of 32 t. In other markets the figure is as much as 10 m³. The HN 2,5 ensures that truck mixers can be filled with 3 or 4 batches. The output capacity was increased in the other existing types of horizontal units by means of modifications. They are now available with capacities from 80 m³ to 184 m³ of compacted fresh concrete per hour (with a mixing time of 30 sec.).
