### Introduction to 4-Ram Electro-Hydraulic Steering Gear
The steering gear system described is a common Rapson Slide type, specifically an electro-hydraulic system utilizing four hydraulic rams acting on a tiller. The system comprises a control system (Telemotor from the bridge), an actuating system (pumps and control linkage in the steering room), and the mechanical assembly (rams, tiller, rudder stock, and rudder).
The primary function is to convert electrical signals from the bridge into large mechanical torque to turn the rudder against the hydrodynamic forces exerted by the water. The system is designed for reliability and redundancy as mandated by SOLAS regulations.
