OSPL hydraulic steering units
Developed for large displacement to minimize flow loss, the OSPL is ideal for large vehicles and supports an extended maximum steering pressure up to 240 bar [3,480 psi] (P-T). It is only available in static and dynamic LS versions.
Features and benefits
- High steering pressure
- Low noise level
- Low pressure drop
- Low steering torque
- High back pressure possible
- Good steering controllability
- Built-in valve functions possible
Applications
- Large forklift trucks
- Wheel loaders
