Discover the reliability and power of the B&G Hydraulic Ram Type 1 12V, a self-contained linear actuator engineered for seamless integration into marine autopilot systems. Ideal for boats ranging from 7 to 10 tons or 11 to 16 meters in length, this compact unit delivers robust performance without the hassle of external plumbing or reservoirs. Boat owners and captains appreciate its ability to handle demanding conditions while maintaining precise control over the rudder.

Seamless Integration with Mechanical Steering

Crafted for vessels equipped with back-drivable mechanical primary steering, the RAM-T1-12V combines a hydraulic cylinder, pump, reversible motor, electromagnetic clutch, and reservoir into one pre-filled, sealed package. In manual mode, simply disengage the clutch for free movement synced with your helm. Switch to autopilot, and the course computer activates the clutch solenoid, powering the motor to extend or retract the ram smoothly. Built-in relief valves safeguard against shocks from rudder hard-over, grounding, or waves, ensuring longevity even in rough seas.

Engineered for Marine Harshness

This ram stands out with its aluminum construction, IP67 ingress protection for submersion resistance, and operation across a wide temperature range from -15°C to +55°C. Compliance with stringent standards like BS EN 60945 for EMC and BS EN 28846 for ignition protection means it's ready for professional installations without compatibility worries. The bi-directional design responds quickly, achieving hard-over in just 13 seconds nominally, perfect for responsive handling on mid-sized yachts or workboats.

Key Performance Highlights

• Maximum Thrust: Up to 700 kg intermittent, with efficient 60 kg at 25% duty cycle.
• Power Efficiency: Low 2A draw for continuous light loads, peaking at 19A for high-demand maneuvers.
• Stroke and Dimensions: 264 mm max stroke in a sleek 101 x 728 mm footprint, weighing only 8 kg.
• Orientation Simplicity: Connect red lead to positive for extension, black for retraction.
• Clutch Reliability: 12-watt coil with DIN 43650 connector for straightforward wiring (6-8 mm cable).

Installation and Maintenance Tips

Mount the ram horizontally or vertically to suit your tiller or quadrant setup, ensuring alignment for full stroke utilization. Wire the clutch via the DIN connector to your autopilot's power steer output for automatic engagement. Use only specified hydraulic fluids to prevent seal degradation—check levels annually or after extended layups. Regular inspection of mounting points and electrical connections keeps it performing flawlessly season after season. Pairing with B&G pilots unlocks power steer mode as a backup during manual steering issues, adding peace of mind offshore.

Why Mariners Trust This Hydraulic Actuator

Unlike bulkier systems requiring custom plumbing, the RAM-T1-12V's all-in-one design slashes installation time and reduces failure points. Its high thrust handles loaded displacement hulls confidently, while low power draw suits battery banks on long passages. Captains report fewer leaks and easier servicing compared to traditional rams, making it a go-to for upgrades on cruising sailboats or fishing vessels pushing 16 meters.
