Equipment manufacturers profit by the Linde Hydraulics transmission concept. Due to the direct conversion of the prime mover speed into wheel speed it is possible to reduce the number of drive line components and the energy losses in the operating cycle.
Linde hydraulic motors offer uniformly high torque for smooth start up. Right from the start.

Linde high pressure units are designed for excellent reliability and long service life. The actual service life of a hydraulic unit is determined by numerous factors. It can be extended significantly through proper maintenance of the hydraulic system and by using high-quality hydraulic fluid.
>> Speed | lower continuous maximum speed |
>> Operating pressure | pressure less than 300 bar Δp on average |
>> Max. pressure | only at reduced displacement |
>> Viscosity | 15 ... 30 cSt |
>> Power | continuous power or lower |
>> Purity of fluid | 18/16/13 in accordance with ISO 4406 or better |
>> Speed | between continuous maximum speed and intermittent maximum speed |
>> Operating pressure | pressure more than 300 bar Δp on average |
>> Viscosity | less than 10 cSt |
>> Power | continuous operation close to max. power |
>> Purity of fluid | lower than 18/16/13 in acc. with ISO 4406 |
In order to guarantee long-term proper function and high efficiency of the hydraulic motors the purity of the pressure fluid must comply with the following criteria according to Linde Works Standard WN 51 210. High purity oil can extend the service time of the hydraulic system significantly.
>> For reliable proper function and long service life | 18/16/13 in accordance with ISO 4406 or better |
>> Minimum requirements | 20/18/15 in accordance with ISO 4406 |
>> Commissioning | The minimum purity requirement for the hydraulic oil is based on the most sensitive system component. For commissioning we recommend a filtration in order to achieve the requiredpurity. |
>> Filling and operation of hydraulic systems | The required purity of the hydraulic oil must be ensured during filling or topping up. Whendrums, canisters or large-capacity tanks are used the oil generally has to be filtered. Werecommend the implementation of suitable measures (e.g. filters) to ensure that therequired minimum purity of the oil is also achieved during operation. |
>> International standard | code number according to ISO 4406 purity class according to SAE AS 4059 18/16/13 corresponds to 8A/7B/7C 20/18/15 9A/8B/8C |
In order to ensure the functional performance and high efficiency of the hydraulic motors the viscosity and purity of the operating fluid should meet the different operational requirements. Linde recommends using only hydraulic fluids which are confirmed by the manufacturer as suitable for use in high pressure hydraulic installations or approved by the original equipment manufacturer.

In order to be able to select the right hydraulic fluid it is necessary to know the working temperature in the hydraulic circuit. The hydraulic fluid should be selected such that its optimum viscosity is within the working temperature range (see tables).
The temperature should not exceed 90 °C in any part of the system. Due to pressure and speed influences the leakage fluid temperature is always higher than the circuit temperature. Please contact Linde if the stated conditions cannot be met in special circumstances.

Based on a standard Series 02 variable hydraulic motor with single shaft end, the PTO Through-Drive Motor features two shaft ends for torque transfer. This enables the hydraulic motor to be installed directly in the drive line without transfer gearbox, reducing noise emission and fuel consumption. At the same time the overall efficiency increases.

The secondary valves (crossline relief valves) protect the system from pressure overload by using two interlinked pressure relief valves (combined with check valves). It is recommended for applications where this protective function is not provided by other means (e.g. through primary protection at the pump or LS valves). The secondary protection includes a make up function. It prevents cavitation and is required in an open loop circuit if the motor requires more oil than is supplied. For special situations like in the swing gear drive the installation of controllable secondary valves is recommended. For equipment options for Series 02 motors please refer to the model code.

Pressure regulated motors shift to maximum displacement at high operating pressure, irrespective of which side is under pressure. In propel drives this can have undesirable effects. For example, if the motor shifts to maximum displacement during the transition phase from straight travel with low system pressure to overrun (deceleration, downhill travel) with high pressure on the reverse side, an extremely strong vehicle braking effect will occur. The signal selection for pressure regulator prevents the regulator being subjected to this braking pressure and, therefore, ensures that the motor remains at minimum displacement. For equipment options for Series 02 motors please refer to the model code.
The counterbalance (brake) valve prevents the motor over speeding during an over-run situation. To achieve this, the motor return flow is automatically and continuously metered such that it always matches the input flow. Different braking responses are
possible. The integrated make-up function simultaneously prevents cavitation. A purge and case flushing function is also integrated. Counterbalance (brake) valves are typically used for drive systems in open loop circuits. The function of the high pressure relief valves can be integrated in the counterbalance valves. Further types of counterbalance valves are shown in section “Dimensions. HMR-02”.

Speed sensors electronically register the motor speed and send an associated input signal to electronic drive controls. Examples are shown below.
Based on the respective system requirements, Linde Hydraulics offers fixed displacement, variable displacement and regulating motors with high starting torque for open and closed loop operation. Optional auxiliary functions, zero displacement capacity and PTO through-shaft enable higher machine design flexibility and increase the efficiency of the travel drive. The motors are optionally controlled electrically, hydraulically or pneumatically.

The cross over relief valve block offers additional high pressure protection for the series 02 motors. It is mounted to the radial high pressure ports. As well as this protective function, the block offers tee connectors for the high pressure connections in order to connect an additional motor to the system without the need for long hoses.

The HMF-02 motor is a high-pressure fixed displacement motor for open and closed loop operation. Secondary valves enable customised definition of soft motor start-up and slowdown. With dual setting secondary valves the maximum acceleration and braking torque is additionally available. The settings and shifting ranges can be adjusted according to project-specific requirements, see sections “Functions. Crossline (secondary) protection” and “HMF-02 P”.

The HMF-02 motor is a high-pressure fixed displacement motor for open loop operation. With integrated LS directional control valve and TC torque control it combines the benefits of the Series 02 with all auxiliary functions typically required for application in swing and winch drives. The HMF-02 P is available in the rated sizes 35, 55, 75 and 105. Differing from the standard HMF, the nominal pressure is 280 bar, the peak pressure is 300 bar.

For powerful and dynamic application in swing drives the TC function enables control pressure-dependent acceleration. Once the maximum rotating speed is reached, torque control is superimposed and pressure level is reduced for energy-saving operation. If the control valve is reset to the neutral position, no additional control signal is generated and the rotary motion slows down uniformly. Active counter-rotation is possible with controllable secondary valves. A counteractive control signal is generated, and the rotary motion is decelerated along the characteristic counter-rotation pressure curve.
