The highest standards of safety

If you like being in the driver’s seat, you’ll love the light responsiveness of our steering units.

It takes a lot to keep steering forces under perfect control in all kinds of driving conditions. With Danfoss hydraulic steering units, a steady, reliable performance is integral to the design. 

Look forward to the highest standards of safety and operator comfort − and a low noise level that the surroundings are bound to appreciate.

Our steering units are available in many types, most of them with integrated valve functions. Perfect for smooth driving on the straight or during maneuvering.

OSPC

Open center and load sensing models.

Features

  • Low noice
  • Good steering controlability
  • Low steering torque 0.8 to 3.0 N
  • High back pressure possible up to 40bar
  • One or several built in valve functions possible: pressure relief, shock and suction in L + R, check valve in P and in LS


Target applications

  • Small tractors
  • Backhoe loader
  • Road building machinery
  • Combines and harvesters etc.
OSPC
OSPD

The OSPD is a dual displacement steering unit, which assures easy maneuverability of machines of most sizes. Each unit in the complete steering range combines superior performance with the highest standards of safety, operator comfort and low noise levels. Due to flexibility in combination of rotary meters, OSPD can be offered with many different ratios between emergency steering and normal steering displacement, ratios between 1:2 and 1:7. OSPD also can be offered with external shift of displacement. In this way can be selected between different displacements to improve comfort and productivity.


Features

  • The OSPD has 2 rotary meters (gear wheel sets). In the case of no pump supply only one rotary meter is active for emergency steering. In normal steering situations both rotary meters are active
  • With OSPD even heavy vehicles can in many cases fulfill legislations and be steered without the emergency steering pump
  • Ratio between normal steering displacement and emergency steering displacement from factor 2 up to 7
  • Low noice
  • Good steering controlability
  • Low steering torque 0.8 to 3.0 N
  • High back pressure possible up to 40bar
  • One or several built in valve functions possible: pressure relief, shock and suction in L + R, check valve in P and in LS


Target applications

  • On-road machinery etc.
OSPD
OSPF

OSPF is the perfect steering units for small to medium size fork lift trucks and compact wheel loaders.

Features

  • Extremely good in controlling negative steering forces, therefore no risk of runaway even when only using one differential cylinder on articulated vehicles
  • Higher max. steering speed, limited only by the capacity of the pump and the pressure setting
  • Low noice
  • Good steering controlability
  • Low steering torque 0.8 to 3.0 N
  • High back pressure possible up to 40bar
  • One or several built in valve functions possible: pressure relief, shock and suction in L + R and check valve in P

Target applications

  • Forklift trucks
  • Combines etc.
OSPF
OSPL

The OSPL has an extended maximum steering pressure up to 240 bar (P-T). It is only available in LS versions (static and dynamic), and has been developed especially for large displacement in order to minimize flow loss. It is therefore extremely suitable for large vehicles.

Features

  • Cover large displacements
  • Higher steering pressure
  • Low noise level
  • Low pressure drop
  • Low steering torque
  • One or more built in valve functions
  • Good steering controlability
  • Low steering torque 0.8 to 3.0 N
  • High back pressure possible up to 40bar
  • One or several built in valve functions possible: shock and suction in L + R and check valve in P


Target applications

  • Large forklift trucks
  • Wheel loaders
OSPL
OSPM

Characteristically fully hydraulic steering systems do not rely on a mechanical link between the steering wheel and the wheels on the ground. This is a major advantage for the vehicle designer and is probably one of the main drivers for the widespread success of fully hydraulic steering systems. However, the absence of a mechanical link leads to a loss of positional relationship between the steering wheel and the wheels on the ground. The relationship between the rotational position of the steering wheel and the driving direction of the vehicle may vary. This is a traditional short coming of fully hydraulic steering systems, and is well understood in the industry. OSPM is available in open center non-reaction, power beyond non-reaction and LS dynamic non-reactions versions.

Features

  • Good steering controlability
  • Low steering torque 1.2 to 2.0 N
  • One or several built in valve functions possible: shock in L + R, pressure relief valve and check valve in P and LS
  • Maximum steering pressure 150 bar (P-T)

Target applications

  • Sweepers
  • Turf care
  • Utility tractors
OSPM
OSPU

The OSPU is the latest addition to the Danfoss dual displacement steering product line, complementing the OSPD for responsive, easily maneuverable machines of most sizes. Each unit in the complete steering range combines superior performance with the highest standards of safety, operator comfort and low noise levels. Danfoss has designed the OSPU as an alternative to dual displacement steering units. Due to its unique flow-amplifying capability (up to 1:4), the unit delivers best-in-class manual steering over a wide application range – the compact design easing installation. A new progressive displacement option secures smooth steering performance in both slow and fast steering modes, while maintaining optimal controllability, precision and operator comfort. The steadily increasing flow, which corresponds to steering speed, contributes to reduced operating costs.

Features and benefits

  • Displacement independent of steering speed
  • Amplification factors: 1:2, 1:2,5, 1:3 or 1:4 linear, or 1:2 progressive amplification versions
  • Steady increase in progressive flow at higher steering speed
  • Increases productivity and driver comfort
  • Installation Benefits
  • Small installation dimensions


Target applications

  • Tractors
  • Backhoe loaders
  • Combines
  • Telescopic handlers
  • Wheel loaders etc.
OSPU
VSP
