Piston Type Steering Gear

Category: Steering Gear

The piston-type steering gear is designed for reliability and is suitable for flat steering gear compartments on vessels such as RoRos and anchor handling tug supply vessels, that require a large rudder angle.

The steering gear is ideally suited for all kind of vessels up to 30,000 dwt and is approved by all classification societies. A separate drive unit means that a flexible arrangement of components is possible and their design also ensures easy maintenance.

Depending on the rudder torque, the steering gear/rudder stock connection can be cylindrical or conical.

Structural features

  • Electro-hydraulic driven
  • 2 differential piston type cylinder
  • Working torque 25 – 1000 kNm
  • For 2x 35°/ 2x 45° rudder angle (larger rudder angle on demand)

  • Independent pump unit with fix or variable displacement
  • Connection to rudder stock by conical hydraulic
  • shrinkfit or cylindrical clamping device
  • Application for single-screw or for twin-screw vessels
  • For twin rudder electrical or mechanical synchronisation possible
