New linear actuators are available that provide boat and other marine equipment manufacturers with an alternative source of push-pull power.
New linear actuators are available that provide boat and other marine equipment manufacturers with an alternative source of push-pull power.
Despite their compact form, modern electromechanical actuators are can handle significant loads.
Operating on 12 or 24V DC, the actuators only draw power when the load is being moved for optimum efficiency and battery life and eliminate the need for hoses, pumps, filters, regulators and periodic maintenance.
Thomson Electrak marine actuators are manufactured with weather protection seals and gaskets ensuring rugged IP66 rated actuation.
"Electrak actuators offer complete control of the key aspects of a boat's operation electrically, without the complication, cost and maintenance associated with hydraulic systems", says Al Wroblaski, Product Manager.
Typical marine applications include the raising and lowering of engine hatch covers, opening and closing windows or seat positioning.
Electrak actuators are also used for boat control, for example boom control when raising or lowering the mainsail and downhaul tensioning.
Using an electromechanical actuator a position can be held without the need for additional props or fixings, built-in brakes are standard on ball screw models to prevent back driving.
Electrak actuators have also been used for many years as gearshift and throttle control applications in "drive by wire" system for utility boats.
Electrak actuators are available with stroke lengths from 25 to 600mm and load ratings from 100 to 6800N.
They feature ball or Acme screw drives for high or moderate load ratings, that hold a load safely if power is lost.
All models are CE approved and also meet UL1500 ignition protection and are easy to install with a clevis mounting.
