Ultraflex electromechanical hatch lifting systems have been especially designed for marine pleasure boats, completely marinized and made of resistant materials that do not need maintenance. They allow full or partial opening and closing, of any heavy door, engine hatch or other equipment on your boat, eliminating manual effort. It is possible to lift the hatch to any desired position from closed to full open by activating a switch. Total safety is guaranteed by the self-locking mechanism of the actuators that prevents accidental hatch closing. In case of power failure an emergency device allows a manual opening. The actuators meet with the current anti deflagration requirements
