DATA designs and manufactures several lines of marine hydraulic steering systems in complete ranges starting from 50 daN.m, as well as steering controls, power units and motor starters ensuring overall system responsibility for all types of commercial – pleasure boats & mega yachts. We have CE classification certificates for our steering systems suitable for boats up to 24 mts. in length and can provide a proportional system, in which rudder movements are accelerated and decelerated, resulting in shockless and noiseless operation of the steering rams. Data hydraulic steering systems consist of a hydraulic pump and cylinder, connected by means of copper tubes, nylon hoses, flexible high-pressure hoses or seamless steel tubes. The cylinder is of the double-acting type and the pump is of the axial piston type, with small pistons inside, which are actuated by the steering wheel. The manually operated system created its hydraulic power through rotation of the steering wheel.

Installation
All you require is to install the pump and the cylinder to their working places and connect the pump to the cylinder by means of copper tubes, nylon hoses, flexible high-pressure hoses or seamless steel tubes.

Maintenance
When it is properly installed, with the help of its maintenance free design, Data steering system needs minimum maintenance.

Reduction of the number of steering wheel revolutions
It is the hydraulic cylinder, which determines the torque of a hydraulic steering system. When a reduced number of a steering wheel revolutions from starboard to port is required, a steering pump with larger capacity should be selected. On the other hand, pump with larger capacity will cause relatively greater load on the steering wheel. An optimum selection should be made by checking “technical specification table”.

It should be remembered that when a larger diameter steering wheel is selected, the force to be applied to the steering wheel becomes relatively lower. The choice of the correct cylinder is determined by the rudder torque (in daNm) which is effected by rudder blade dimensions and the speed of the vessel.

Power operated hydraulic steering systems
DATA offers various types of hydraulic power units complete with steering controls and motor starters the can be combined with the standard range of DATA hydraulic steering cylinders. Hydraulic power units can be 24 V DC, 22 V AC / 380 V AC electric motor driven or main engine driven meeting all customers requirements.
