1 The unbeatable driving experience for applications with engine speed control. Telehandlers, Wheel Loaders, Farmyard Loaders, Dumpers...

2 A focus on man and machine. Machines with a speed-dependent control like telehandlers, wheel loaders, farmyard loaders or dumpers have one thing in common: they place the highest demands on the propel drive system as well as on the driver. Due to the wide variety of uses in agriculture, construction and material handling, mastering the various complex work functions of the machine simultaneously is essential. The actual driving is always an integral part of the work function and therefore acts as a decisive factor for your machine s economic efficiency, no matter whether it involves the powerful handling of bulk materials, precise stacking of hay bales or fast transport from A to B.

4 For maximum economic efficiency and the best possible performance. Simple and intuitive operation of the propel drive makes for improved driving comfort and enables non-fatiguing working, which actively relieves the burden on the operator. This results in a clear increase in productivity of the entire working system and ensures its optimum utilisation. If an operator feels in complete control of the machinery, his work will be more effective and the machine will be able to operate with maximum economic efficiency. This is exactly where the unique LinDrive driving philosophy from Linde Hydraulics applies. LinDrive puts the focus on the entire working system, i.e. man and machine, and all of this from the project planning and product development stage to commissioning and serial production. Our team of development, sales and application engineers focuses not just on achieving optimum utilisation of the available engine power and absolute reliability of the propel drive as the central design criteria, but also on simple and intuitive operation. This enables LinDrive to offer custom-made solutions for your propel drive system.

5 LinDrive = Precision Dynamics Reliability = Benefitn What are the special features of machinery fitted with LinDrive? Precision Precise manoeuvring thanks to direct machine control Simple, intuitive operation Non-fatiguing working Precision control Excellent continuity of movement Optimum efficiency Dynamics Dynamic drive behaviour through optimum utilisation of the installed power Rapid reversing Dynamic acceleration and braking High transfer speed Defined load characteristics Enhanced handling performance Reliability Total reliability thanks to high operational availability of drive components and high safety standards Application-optimised Operating statuses can be exactly reproduced Defined machine response to system failure Meets high requirements of road traffic admission Optimum safety for operator and his environment

6 Your tailor-made system with the right component selection. Precision, dynamics and reliability. These typical LinDrive advantages feature in all our propel drive concepts. Linde Hydraulics has specially developed the HPV-02 CA for use in various applications like telehandlers, wheel loaders or dumpers. It enables engine-speed-dependent driving that is exactly coordinated with the pressure requirements of the driving status and the installed engine power. In combination with our fixed displacement, variable displacement and regulating motors in single as well as double-motor configuration, the HPV-02 CA enables the design of highly individual propel drive systems that are tailored to the diesel power, maximum driving speed, degree of resolution and conversion type: either direct or via transmission stages. Selection of pump/motor based on speed and torque (pump speed 2300min -1 ) The layout diagram below enables the initial selection of the required nominal sizes of the hydrostats and the selection of the motor types. Example: the optimum use of the conversion range is reached by a variable displacement motor HMV and a HPV CA. If the HPV-02 CA is combined with a fixed displacement motor HMF , the maximum hydraulic motor speed cannot be reached.

Compact working machines require compact drive solutions. The conventional design of propel drives for wheel loaders, telehandlers or dumpers is based on a fast rotating variable displacement motor, the speed of which is reduced to the wheel speed via several transmission stages. The disadvantage: loss of mechanical efficiency, increased windage losses and high noise levels. As an alternative, our large-displacement PTO Through-Drive- Motors offer the option of reducing the hydraulic motor speed and the number of drive train components. This is due to PTO single and double-motors having two shaft ends for torque output. This enables these motors to be installed directly into the drive train. The direct installation and high conversion range of these largedisplacement hydraulic motors provide decisive advantages: - Increase in installation space - Fewer interfaces and parts - Less noise - Increased overall efficiency - Reduced fuel consumption

9 Even better with the HPV-02 CA. Whether accelerating or braking, highly dynamic driving and variable distribution of power are the main issues for wheel loaders, telehandlers and dumpers. As a consequence, the hydraulic pump is actuated indirectly via the diesel speed instead of directly via the control pedals. This ensures that the displacement characteristic of the hydraulic pump determines the machine s drive behaviour. The HPV-02 CA offers functional quality, comfort and safety at the level of electro-hydraulic actuation. Precise power control settings enable full utilisation of the available power. The torque control and performance limiter can be variably defined. In this way, the HPV-02 CA ensures individual driving characteristics adjusted to your requirements Geschwindigkeit [km/h] Speed [km/h] 10 Driving behaviour HPV-02 CA with variable motor HMV-02 EH1P CA with pressure regulation Drehzahl [min-1] rpm [min-1] Hochdruck [bar] High Pressure [bar] Geschwindigkeit [km/h] Speed [km/h] with variable motor HMV-02 EH 1P CA with pressure regulation with regulating motor HMR-02 Speed map for HPV-02 CA.

10 Seeing the bigger picture. Improving the details. Our goal is to increase the driving comfort and the economic efficiency of your machine. The individual goals of increased precision, dynamics and reliability are not only achieved by optimum design and adjustment of the driving system. We already focus on this goal during the development of individual propel drive components. This ensures that the HPV-02 CA offers all typical LinDrive advantages. Precision Continuously variable selection of driving and operating speed via the accelerator pedal through the integrated charge pump for hydrostatic speed sensing - temperature independent - pressure compensated - performance optimised - low noise level The same driving signal always triggers the same machine reaction through position feed-back control - independent of traction forces and loads - reproducible - foreseeable - precise - low in hysteresis Hydrostatic braking through maximum swashing torque - load independent - pump control not influenced by braking pressure Optimum reversing through co-ordinated swashing behaviour of pump and hydraulic motor - gentle transition from braking to acceleration - braking phase can be defined for each application The high swash forces of the pump control lead to the prompt swashing of the pump, independent of tractive effort and load. They also guarantee the direct conversion of the driving signals maintaining driving dynamics at a constantly high level. The maximum swash force of the pump control ensures the precise conversion of the driving signals, independent of the step stroke. Absolutely foreseeable and reproducible.
