Rotary Vane Steering Gear · Steering Gear
The MacGregor Hatlapa PTR is a rotary‑vane hydraulic steering gear that provides high torque and precise rudder control, featuring redundant power packs to meet SOLAS requirements. As a Rotary Vane Steering Gear, it is normally installed in the steering-gear room, bow or stern thruster compartment, or propulsion-control system according to the listed equipment. In that role, its primary purpose is to control vessel heading or generate transverse or directional manoeuvring thrust. Ram and rotary-vane steering gears, tunnel thrusters and retractable azimuth units use different actuators and propulsors but all depend on reliable hydraulics or electric drives and feedback control. Capacity: Up to 50,000 kNm. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
