2 02 linde hydraulics portfolio Linde Hydraulics. Turning Power into Motion. At Linde Hydraulics we have always had a passion for converting power into motion. This passion is driven by customer care, a thirst for knowledge and a love of innovation. We power ideas, machines and markets, both today and in the future. We combine components to a system and create efficient overall solutions thanks to our intelligent blend of hydraulics, electronics and mechanics. Our aspiration can be summed up by one simple concept: Adding customer value through application expertise and the pursuit of system perfection. Linde Hydraulics makes all of this possible due to a combination of partnership, responsibility and the highest level of commitment. For us, partnership is an important, indispensable part of product development and quality assurance. Therefore, we add our knowledge, experience and international market expertise to help you exceed your customers expectation. We strive to be your best partner from initial contact to project engineering and product development, all the way through prototype commissioning, serial production and training your teams. Our interpretation of the term customer orientation is superior service and availability: worldwide, at any place. With companies in Europe, USA and China along with a great international network distributors we guarantee you the best possible customer service. Portfolio. By the logic combination of individual products that perfectly complement each other we offer solutions for almost every class of machines. Due to these capabilities we can always offer the best possible system to our customers. see application example on page 4 Drive Pump 2x HPV 55 2x HPV 75 2x HPV 105 2x HPV 135 2x HPV 165 2x HPV 210 2x HPV 280 4x HPV 210 Drive Motor 2x HMV 75 2x HMV 105 2x HMV 135 2x HMV 165 2x HMV 210 2x HMV 280 4x HMV 165 4x HMV 210 4x HMV 280 6x HMV 280 Implement Pump MPR 50 HPR 75 HPR 105 HPR 135 HPR 165 HPR 210 MCV VW 12 VW 14 VW 18 VW 25 VW 30 5t 10t 15t 20t 25t 30t 35t 40t 45t 50t 55t

3 Benefits of Hydrostatic Drive Systems 03 Benefits of hydrostatic drive systems. When compared with torque converters. Dozers benefit from the use of a modern hydrostatic drive system most notably in terms of a very high productivity and low fuel consumption. In addition to that the hydrostat demands less service since a shifting gearbox can be omitted and the mechanical brake is not needed for deceleration. The amount of oil to be changed is lower and the wear of the fluid itself is less. But the best of that all these benefits remain valid over the whole lifetime of the machine without readjusting or the complete exchange of the hydrostatic components. The hydrostatic drive system offers more higher efficiency faster reversing better general controllability superior fine control easier to maintain Hydrostatic drive systems have proven to be superior over hydrodynamic drives systems in various types of machines. Beyond the general advantages of the hydrostatic drive, Linde drive systems offer an unbeatable driving experience in terms of precision, dynamics and reliability. Linde drive units offer load independent, direct unit control various types of controls reliable and robust yet most compact design through drive capability for pumps and motors smooth and sensitive operation even at low speeds low noise The hydrostatic drive system takes less less losses and therefore less fuel consumption and less emissions no unintentional movement of machine like rolling back less components in the drivetrain, therefore no wear and tear of brakes and gearbox less service needed, less amount of oil to be changed 2 1,8 1,6 1,4 1,2 Speed ratio 1 0,8 0,6 0,4 0,2 0 LinDrive = Precision x Dynamics x Reliability = Benefit n Engine Pump Motor Low speed direct Low speed integration Gearbox Differential Planetary gear Wheel Low speed High speed

Equipment 2x HPV E1 (travel circuit pumps) 2x HMV E1 (travel circuit motors) 1x HPR LP (working hydraulics pump) 1x VM14M3 (working hydraulics) 1x Electronic control unit 1x Joystick Advantages hydrostatic drive system without splitter gear box and manual gearbox infinitely variable precise, controlled even travel wear-free steering extremely robust and durable series 02 units high thrust performance precise results low consumption Individual control of the drivetrains also allows precise turning curves to be achieved, right through to turning on the spot without increased risk of wear to the brakes or chain. The motors are extremely robust when it comes to rapid angular acceleration, which makes them immune to tracks which skip a tooth on the sprocket. Thanks to the large spread of the hydrostatic power train, there is no need for a manual gearbox and the machine can be driven stepless from standstill through to high speeds. The optimal traction means that thrust performance is always constantly high, even during cornering. Fuel consumption is comparatively low, even at full load. The high efficiency level of the hydrostatic drive units and an electronic power limit control ensure the diesel motor is working at favourable operating points all the time. The robustness and durability of all series 02 components makes them a reliable drive technology solution for heavy machinery in the toughest conditions, as demonstrated by this example of a bulldozer. In addition, Linde components also help you to realise ambitious targets when it comes to fuel consumption and ease of operation, even at full load. The machine operator simply sets the desired speed with the joystick and the electronic controller ensures even, straight travel. A control circuit has been developed for this purpose, as the following diagram shows. Two identical drivetrains consisting of a variable displacement pump and a variable motor each supply one side of the bulldozer. The speed of the motors is constantly monitored by speed sensors. If different ground conditions, obstacles, and other factors require an adjustment to the rotational speed or torque, the relevant units are controlled in relation to the current situation and the speeds of the two drivetrains are coordinated.
