Now a new option enables effortless tool control and flexibility. Both high-performing features are the result of a long working relationship with Sauer-Danfoss. Wolfgang P. Weisser Vice President Sales & Marketing Europe 2 Road maintenance could hardly be a smoother, more efficient experience than with ERGOS tractors from RENAULT Agriculture. Marketed as the tool carriers for road maintenance professionals, their optional hydrostatic transmission and integrated electro-hydraulic control system have taken performance to new heights. Sauer-Danfoss supplies the CAN-Bus valve and joystick for the latest of the two options – the electro-hydraulic FRONT PILOT, which gives tractor drivers untold flexibility and control when trimming ditches, pruning roadside vegetation, removing snow and performing other road maintenance tasks. xible control Simple configuration The FRONT PILOT comprises a single PVG 32 valve, supplied in three sections with a PVBZ loadcompensated module, PVED electrical actuator and customized diverter valve. Full integration in the tractor eliminates the need to fit a valve both at the front and back to control hydraulic flow. Not only does this reduce the number of components on the tractor, the operating parameters for individual tools can be set via the CAN-Bus in the PVG 32 – making it possible to add virtually any tool whether it has CAN-Bus or not. Ergonomically designed for comfortable operation, the Sauer-Danfoss Prof 1 joystick on the FRONT PILOT is easily configured to accommodate any number of tools. All the driver has to do is select the tools from the display menu, adjust the parameters as necessary and the joystick is automatically set. Up to 10 drivers can store their individual preferences in the control system's memory. Automotive control A high degree of flexibility is also a distinguishing characteristic of the HYDROSHIFT transmission, which comprises the Sauer-Danfoss Series 90 pump with NFPE control, hydrostatic Series 51 bent axis motor with PC control and S1X microcontroller. After several years on the market, the HYDROSHIFT is still unique in its ability to provide a constant engine speed, the automotive control providing continuous variation in ground speed from 0-10.5km/h [0-6.5 mph] in the field and 0-30 km/h [0-18.6 mph] on the road. 3 The newly introduced NFPE control, which balances transmission ratio with engine speed, desired propulsion speed and load conditions, adjusts the ground speed automatically to the volume of vegetation or snow being cleared. This eliminates all levers and simplifies driving in the process. Driver comfort is further enhanced by the OSPC steering unit, which Sauer-Danfoss has long supplied for all RENAULT tractors – evidence of the close working relationship between the two companies. Now this relationship has once again born fruit, creating options many will find hard to dismiss. Article 1. For further information: [email protected] the circuit Launch on world stage The world's largest gathering place for the construction and construction materials industries provided the perfect setting for the launch of the new H1 and PVG 100 valves series from Sauer-Danfoss. Held every three years, CONEXPO-CON/AGG with IFPE attracted more than 2,100 exhibitors to Las Vegas from 15-19 March. Some 100,000 industry professionals from 120 countries attended the event, typically decision-makers from all segments of the construction, aggregates and ready mixed concrete industries. The Sauer-Danfoss booth was largely dedicated to the major new additions to the product range, a press conference drawing even more attention to the new H1 family of hydrostatic pumps. At the heart of Sauer-Danfoss launched the first phase of a comprehensive new range of hydrostatic pumps and motors at IFPE/CONEXPO in Las Vegas. A sophisticated response to the move towards more electro-hydraulically driven mobile machinery with higher functionality and improved performance, H1 is designed to meet the next two decades of mobile hydraulic requirements. Higher output speeds, lower input speeds and a total installed lifecycle cost headed in a downward direction – H1 is the answer to all these demands and more, taking servo-controlled hydrostatic pumps and motors into a future of increasingly complex functionality and simpler, more compact designs. H1 is a whole new range of pumps and motors for the global medium and high-power markets and reinforces Sauer-Danfoss' strong capabilities as a total system supplier. Closed circuit variable piston pumps, fixed piston motors, variable piston motors and PLUS 1™-compliant control software and hardware will eventually all be included in the range, which is scheduled for launch over the next two years. Sauer-Danfoss presented the first H1 pumps at IFPE/CONEXPO, including 45, 53, 78, 147 and 165cc/rev displacements. The 45 and 53 cc/rev models are also available as integral tandem pumps. Once fully introduced, the H1 range will comprise some 30 displacements and/or configurations. New technology platform Compact, robust and supremely flexible, H1 is the culmination of a global Sauer-Danfoss project, which has drawn on the company's international expertise to create a range that meets the needs of OEMs worldwide. Product portfolio manager Frank Ramm explains: “By focusing on medium and high power, the aim was to improve the quality and performance of closed 4 tomorrow's mobile machinery circuit propel drives. The result is a future-oriented technology platform that covers the differences in the European, Asia-Pacific and American markets.” One objective was to develop solutions based on fewer parts with a higher level of sophistication and functionality. This achievement is clearly illustrated by the swash plate design on the H1 displacement pumps. Using advanced machining technology, the new swash plate is forged out of a single piece of steel, reducing the part count, improving reliability and lowering the overall lifecycle cost of the final machine. It also allows the same electric displacement control to be used for the entire pump family – a benefit that eases servicing and operator training. An OEM call for lower engine rpm and improved fuel combustion has motivated Sauer-Danfoss to concentrate on the high operating efficiency of the H1 family. The demand is largely driven by the US Tier 3 engine standard for emissions, which the US Environmental Protection Agency plans to phase in beginning in 2006 for off-highway diesel vehicles over 50hp – and which engine and equipment manufacturers in Europe and Japan are expected to follow. But while the pump input speed is reduced, the output speed of the motors will be raised.The higher corner horsepower capability of the H1 bent axis motors promises to optimize tractive force and speed, securing a constant, all-round performance. Clever controls Design flexibility Another distinctive feature of most H1 pumps is their shorter length.The larger pumps in particular are dramatically shorter, giving OEMs greater flexibility in their machine designs. Integrated in the driveline control architecture, the PLUS 1 micro-controller eliminates the need for external mechanical or hydraulic controls and gives improved configuration flexibility when setting parameters for speed, acceleration and so on. In applications such as skid steer loaders, the micro-controller brings the opportunity to replace 5 heavy levers with a joystick for improved driver comfort. “H1 is designed around the use of electrical actuators and controls, giving complex functionality. An electrical interface and the integration of onboard pressure, speed and angle sensors is the only way to achieve the smarter systems that will be increasingly required,”says Frank Ramm. While the pumps and motors contribute the desired level of functional capacity, the PLUS 1 package of hardware and software modules tailors a total H1 system to the application needs of any region – the traditionally high-power market of Europe, with its trend-setting forestry industry; the well-established medium-power market of the US; or the fast-developing Asia-Pacific region, where the market for Chinese construction machinery grew 30% from 2002-2003. With H1, a world of opportunity has opened. Article 2. For further information: [email protected] the circuit Reliable, responsive Battery-powered warehouse trucks from Rocla are gaining ground in Europe, where the prominent manufacturer achieved a volume increase of more than 30% in 2004. As a supplier of motors and inverters to Rocla vehicles, Sauer-Danfoss is proving its ability to deliver complete electric drive systems. Strategic strength Sauer-Danfoss had a firm eye on the future when it became a leading manufacturer of low voltage AC and DC motors overnight in 2002. The acquisition of Denmark-based Thrige Electric, including Schabmüller GmbH in Germany, was the perfect complement to SauerDanfoss' new series of electronic power steering equipment. At the same time, Sauer-Danfoss acquired Schwarzmüller GmbH with its range of battery-powered AC inverters. The acquisitions added new drive technology to the Sauer-Danfoss portfolio of hydrostatic systems – putting the company in a strong position to meet the current and future demands of the material-handling market. 6 and totally electric DC technology is fast giving way to AC in the forklift truck industry. And Finnish Rocla is the first manufacturer to test the advantages of using Sauer-Danfoss to supply both the AC induction motors and AC inverters for the electric drive. Sauer-Danfoss' full range of squirrel-cage AC induction motors can be supplied with or without an integrated feedback sensor. In combination with a battery-powered dACi® inverter, they are ideal for drive, lifting and power steering purposes. The initial development project successfully completed, drives and controls team manager at Rocla, Hannu Lehtinen expects to draw increasingly on Sauer-Danfoss as a total system supplier. Optimized control “As the supplier of the whole system, Sauer-Danfoss guarantees the functionality. We have found the system to be reliable and are very satisfied with the way Sauer-Danfoss has worked with us,” he says. Rocla has used low voltage dACi® inverters from Sauer-Danfoss for some time on a number of its pallet trucks. The company's entire range of automated guided vehicles (AGVs) is fitted with Sauer-Danfoss' compact DC motor in wheel drives (MIWD). Here, too, Rocla has plans to go over to AC technology in the near future. Low maintenance AC technology brings clear benefits in terms of performance, usability and maintenance. The brushless AC motor is virtually maintenance free, while the AC inverter that controls the motor contributes to improved responsiveness and precision in terms of speed, turning and lifting. Operators of battery-powered trucks also experience a smoother, more comfortable drive. Series F is the most recent addition to the comprehensive inverter range, containing all the latest technology despite being among the smallest on the market. CAN-based communications for optimized machine control and a new driver board for external devices, including horns, valves and an electro-mechanical brake, are among the top features. Insulated metal substrate (IMS) technology ensures efficient power utilization. In cooperation with Rocla, Sauer-Danfoss is working to incorporate these benefits in Rocla's product portfolio. Sauer-Danfoss Team manager Thomas Visti explains: “When supplying total systems, we are responsible for technical optimization. The goal is to meet or exceed customer expectations in all areas, including quality, innovation, flexibility and total value.” AC or DC? What are the differences that make AC (alternate current) systems preferable to more traditional DC (direct current) solutions? • AC motors have no brush or commutator, making them highly robust and almost maintenance-free. • The AC inverter that controls the motor is more responsive and precise. • Although the cost of AC and DC systems is currently similar, the falling price of electrical components is expected to cut the cost of AC systems in the future. Rocla's experience so far is that Sauer-Danfoss lives up to these objectives. “Sauer-Danfoss is very open, listens to our requests for changes and has a good response time,” says Hannu Lehtinen.“We are very confident about the results and pleased with the way our first complete project was put together.” “Sauer-Danfoss is very open, listens to our requests for changes and has a good response time,” says Hannu Lehtinen.“ We are very confident about the results and pleased with the way our first complete project was put together.” Article 3.

With the long-awaited Highway Bill promising to inject another $300 billion into the US road network, leading manufacturer of highway pavers Ingersoll-Rand is in a strong position. So, too, is Sauer-Danfoss, which supplies the complete hydraulic systems for the heavy-duty machines. Dependable components are crucial to the design of Ingersoll-Rand’s high-capacity pavers. The astronomical expense involved when a machine breaks down in the field can cause lasting damage to a hard-earned reputation. So it is no surprise to find out that reliability is the company’s top priority when selecting a hydraulic supplier. mechanisms on the asphalt-spreading screed, cooler bypass, ventilator, generator, hitch and vibration systems. Hydraulic front-wheel assist promotes good traction and maneuverability, while sensors and electronics secure slope control. The steering system includes an OSPB steering unit and OTP steering column. “When designing equipment, we involve Sauer-Danfoss early in the process so they can learn our objectives, size the components and design the hydraulics for simplicity and reliability. One Sauer-Danfoss employee, Joe Greenawalt, is permanently placed at our facility, and he brings in additional resources as required,” says Scott Wiley. Ingersoll-Rand and its German subsidiary ABG adapt their screed technology to the needs of the global market, producing pavers with a paving width of up to 52 feet (16 metres). In the US, “If the paver goes down, the whole system goes down – the hot asphalt in the hopper, the crew, the rollers,” explains commercial marketing manager for Ingersoll-Rand’s transportation segment, Scott Wiley. “When marketing our machines we stress reliability and the diagnostic system we have built in to minimize downtime and simplify repairs in the event of electric or hydraulic problems.” System responsibility Sauer-Danfoss meets the whole range of hydraulic requirements – supplying Series 90 pumps and Series 51 motors for the propel drive, and Series 45 pumps, orbital and gear motors, and various HIC solutions for the work functions. Compact and efficient HIC valve solutions, gear pumps and motors are also responsible for the control 8 screed compaction is achieved using a vibratory system for layers of asphalt that are typically 3 to 6 inches (7.5 to 15 cm) thick. Pavers for the European and Asian markets, where the road thickness can exceed 12 inches (30 cm), are usually designed with a tamping system – although, over the last two years, high investments in airport construction have brought more European-style screed technology to the US market. Sauer-Danfoss pumps supply the hydraulic flow to both vibratory and tamping systems. “As industry specifications and requirements evolve, we are continually looking for ways to enhance our existing models or incorporate new technologies in new models. We are currently developing a new line of pavers which incorporates a hydraulically-driven generator to support electrically heated screeds and the power requirements for night paving,” says Scott Wiley. systems Optimizing performance Road building market manager for Sauer-Danfoss in the US, Dave Downs sees Ingersoll-Rand as a model example of the market trend towards fewer suppliers with more system responsibility. “It’s where we want to go as a company, and it’s where they want to go,” he says. The next step for Sauer-Danfoss is to introduce PLUS 1™ control systems to the paver market. “PLUS 1 has numerous advantages over the current systems on the market and will give us an opportunity not only to provide hydraulic components that match system requirements but also the electronic control systems that can optimize hydraulic performance,” says Dave Downs. “We can also interact with other non-hydraulic functions to optimisze the overall performance of the machine in terms of fuel economy, noise reduction and optimal paving.” While the US road industry continues to blossom, Sauer-Danfoss is confident of getting the PLUS 1 message across. As companies like Ingersoll-Rand recognize Sauer-Danfoss’expertise as a full-system supplier, more highly customized solutions will be getting on the road. Article 4. For further information: [email protected] Cool motors cut emissions Two new series of electro-hydraulic proportional fan drive motors have strengthened Sauer-Danfoss as a fullrange supplier of modulated fan drive systems. Tougher emission laws in Europe and the US have made proportional electric control an essential feature on modern fan drives. At the same time, vehicle designers want compact, integrated solutions for maximum mounting flexibility. Sauer-Danfoss has developed the new SNM2Y and SNM3Y fan drive motors to satisfy all these demands, covering Group 2 motors with displacements from 8 to 22cc/rev and Group 3 motors from 22 to 44cc/rev. By combining the motors with Sauer-Danfoss gear pumps, dedicated fan drive or PLUS 1™ controllers and air/liquid temperature sensors, OEMs can find everything they need for a complete fan drive system under one roof. Both the SNM2Y and SNM3Y are based on the high-performance Sauer-Danfoss gear motors. A proportional solenoid bypass relief valve is inte- grated in the rear cover, controlling the oil flow through the motor and, consequently, the fan speed. By this neat arrangement of the electrohydraulic proportional controls, Sauer-Danfoss has given the motors the compactness OEMs seek – reducing the number of hoses and fittings,shortening the installation time and giving great design flexibility when mounting the radiator or fan. Low-power consumption The variable fan speed ensures only the necessary amount of power is consumed to maintain optimum engine and hydraulic system temperatures – in some cases, the fan drive only runs at full power for 5% of the operating time. In this way, OEMs can satisfy the US Tier 3 and European EURO 4/5 emission standards, not to mention cut noise levels and improve fuel economy. And, thanks to their high-quality design, the SNM2Y and SNM3Y can be depended on for their long-lasting performance. After more than 40 years at the helm of the fan drive industry, Sauer-Danfoss has the knowledge to tailor systems for any on- and off-highway vehicle. Electro-hydraulic proportional motors meet the need to cool faster, hotter engines in the face of new emission controls. Article 5. For further information: [email protected] 9 the circuit Sense the load, share the flow The best response to a complex need is often a simple solution. That is exactly what Sauer-Danfoss has developed with the PVG 100, a new load-sensing valve for OEMs seeking higher performance with less horsepower. How can vehicle hydraulics achieve more with less? The PVG 100 is the next step forward in the load-sensing open circuit systems that increasingly provide the answer – enabling vehicle manufacturers to meet stringent emission requirements while their machines grow in size and capability. Launched at IFPE/CONEXPO in March, the PVG 100 is a post-compensated, load-independent directional control valve for limited energy hydraulic systems with flows up to 180lpm and pressure up to 350 bar. Successful tests in forestry, telehandler, construction, forklift and other applications that require fast, precise control and maximum productivity have demonstrated the potential of the PVG 100 to achieve OEM objectives. Optimizing performance Customized valve assemblies The compensator in the PVG 100 brings a flowsharing functionality to load-sensing open circuit systems. This means the flow is distributed proportionally to multiple machine functions with variable load and pressure requirements so, even in conditions where there is insufficient flow, each function remains operational relative to the others. For manufacturers under pressure from tougher emissions laws, flow sharing is an opportunity to optimize flow without sacrificing productivity or increasing energy consumption – giving OEMs a better performance with less horsepower and limited hydraulic flow. To fulfill safety needs and provide system integration, a priority flow of up to 60lpm is available for steering and braking. In designing the PVG 100, Sauer-Danfoss has built on the success of its popular PVG 32, creating new opportunities to match the valve requirements of specific applications. Both valve series utilize common hardware and can be mounted together in customized valve assemblies – advantages that reduce the number of potential leak points, hoses and fittings and installation time. Like the PVG 32, the PVG 100 can be used with mechanical, hydraulic and electrical actuators and can be seamlessly integrated with the new PLUS 1™ electronic control systems. Sense the load, share the flow Flow sharing further enhances the ability of the PVG 100's close center load-sensing system logic to secure optimum energy and control management. Even more performance is provided by regulated pilot-operated check valves which, integrated in the work ports, reduce port leakage to an absolute minimum for top load-holding stability and smoother operations. Such a high level of compatibility provides the basis for flexible, modular valve packages that meet OEM needs more closely than ever. Among the other benefits that OEMs will welcome are a shorter development timeline and a reduction in total installed system costs. On markets moving towards more load-sensing valve solutions, the PVG 100 is reliable, responsive and ready for a challenge. Rely on it.

For further information: [email protected] Heavyweights get extra pull Controlled conveyed power up to 125 kW Larger and heavier implements place a growing burden on the tractors that have to tow them. Sauer-Danfoss can now help customers lighten the load while increasing productivity, even in the most unfavorable conditions. More lightweight tractors loom on the horizon – and that is despite the fact most agricultural and construction machinery is becoming progres-sively heavier. A mathematical model has been developed by Sauer-Danfoss to calculate optimized tractor-trailer combinations, using wheel-assisted drive to turn trailer wheel resistance into useful traction. The wheel-assisted drive model eliminates the need for extra tractor weights when transporting trailers up to three times the weight of the towing vehicle. By calculating the optimum transfer of power from the tractor engine to the trailer, the model is a reliable means to top performance. Sauer-Danfoss also has the components to put the calculations into practice. Developed in cooperation with one of Denmark's leading engineering universities, the model simulates various driving situations in relation to ground conditions and the impact of wheel pressure and slip on the ground surface. The resulting performance curves form the basis for designing a wheel-assisted system that gives faster propulsion on the flat and improves the ability to drive up steep gradients, wet or dry. By transferring power in proportion to the tractor-trailer's weight distribution, farmers gain from reduced soil damage in muddy conditions – a benefit that enables an earlier start to slurry spreading – and construction workers can continue working efficiently on the wettest of sites. How much power can be conveyed to the trailer wheels depends on the transmitting capability of the tractor's power take off shaft (PTO) and whether or not the work function also requires power while the vehicle is moving. A potato harvester, for example, requires power for the harvesting and cleaning processes. In most cases, the power will be transferred via a cardan shaft, which then drives a hydraulic pump connected to a wheel motor. Fully hydraulic power transfer from the tractor to trailer is another viable option. A Sauer-Danfoss wheel-assisted drive makes all the difference on a tipping trailer from Dewa in Belgium. In this specific example, 125kW are transferred to the trailer where a Sauer-Danfoss Series 90 variable pump and motor provide a reliable and controlled wheel-assisted drive.The wheel-assist power is regulated by a PLUS 1™ controller, which communicates with the variable sensors and controls the power accordingly. Whether controlled in terms of weight distribution, wheel slip, tractive force or manual operation, wheel-assisted power ultimately means improved efficiency and productivity for the agricultural and construction industries. Customized wheel-assist systems based on the Sauer-Danfoss model maximize the benefits – embracing a future with lightweight tractors and heavyweight trailers.
