Higher power density for hydrostatic propel drives
Pressure increase for series 02 enables greater output and downsizing of drives. Raise the performance limit of your machine. A higher pressure level generates more torque from the same size of hydrostat. Extensive testing has demonstrated the durability of the 02 Series, even at working pressures of up to 500 bar. The Plus for your driving performance. The benefits this higher pressure range of the hydrostatic drive now offers for both the construction equipment manufacturer and the operator are quite obvious. The additional pressure can be utilized to achieve higher travel speeds. This only requires the use of a longer gear ratio in the working and road travel gear. Or one uses the 20% torque increase to provide the driver with a 20% higher tractive effort and thus higher power reserves. This increases the productivity of construction equipment. As an example, the tractive effort of a wheel loader equipped with a combination of HPV 75-02 CA (pump) and HMV 135-02 (motor) can be increased from 50 kN to 60 kN - without any extra costs and additional weight. Another example: A telescopic handler with hydrostatic propel drive consisting of a pump HPV 55-02 and a motor HMV 165-02. In this case only the transmission ratio needs to be adapted to be able to increase the travel speed from 32 to 40 km/h. Such improvements can always be achieved with high energy efficiency. Utilizing this higher pressure range increases the power density of hydrostatic equipment while nominal sizes remain unchanged. This is why the p+-concept is an excellent choice also under the aspects of fuel economy and environmental protection.
- More tractive effort for enhanced gradability
- Higher driving speeds
- Less space required by downsizing
