A HYDRAULIC STEERING ARRANGEMENT FOR A THRUSTER OF A MARINE VESSEL

摘要

The present invention discusses a novel design of a hydraulic steering arrangement for a thruster of a marine vessel. The hydraulic steering arrangement of the invention is specifically designed for thrusters intended to operate in an arctic environment where ice is present. To meet the arctic demands the steering arrangement is provided with a cross-over safety block (80) arranged close to the hydraulic steering motor (8) for absorbing the torque subjected to the thruster (1 ) by ice for instance.
