Bow Thrusters Overview

 

Installation and Maintenance

All units are supplied with a comprehensive instruction manual.

Our joint experience working with shipbuilders and repairers has influenced the design of our thrusters, resulting in lower installation costs and more reliable commissioning.

Hydraulic services and testing can be carried out on site in conjunction with Hercules Hydraulics.

Our intelligent wheelhouse controller gives big boat performance at small boat cost.

The Thruster Controller is a 24V DC unit, seadled to IP65 standards for wheelhouse or protected external locations only. Thrust control is via a proportional "put and stay" joystick. Each unit can be selected for duty or set to standby and monitors four alarms. The unit is pre-wired, tested and supplied with plugs and two metres of cable.

Incorporating a proportional control, warning lights and a test for alarm it can be integrated with an autopilot and either single or multi-station systems with full control can be supplied.

Kort Thrusters is the result of a long-standing formal joint venture between Hercules CSMD and Kort Propulsion Company Limited.

Our thrusters are primarily designed for commercial displacement vessels but have been successfully fitted to planing craft and inland waterways pleasure craft.

Long service life and ease of maintenance have been key factors in design and development.

Models KT30-KT170 have the hydraulic motor fitted in the drive housing directly coupled to the propeller shaft which runs in taper roller bearings housed in the nose cone assembly. These are pre fitted and tested prior to delivery.

Models KT200-KT300 have a lower gearbox within the tunnel with the hydraulic motor plugged into the input housing inside the vessel. These larger units can also have diesel drive via a cardan shaft and right angle gearbox. A range of ratios is available to suit engine rating.

All models can be supplied to suit a range of system operating pressures and can be integrated with either closed loop or open loop hydraulic systems.

All units are supplied with a comprehensive instruction manual.

Our joint experience working with shipbuilders and repairers has influenced the design of our thrusters, resulting in lower installation costs and more reliable commissioning.
