The Uflex AV hatch lifters are electromechanical products, especially
designed for marine use on pleasure boats. They allow full or partial
opening and closing of heavy engine hatches, peak tanks, hatch beams
etc. By activating a switch, it is possible to lift the hatch to any
desired position from closed to full open; an internal self-locking
mechanism will maintain the position preventing any accidental hatch
closing. In case of a power failure an emergency device allows for
manual opening.
According to the load required, the Uflex AV hatch lifters can be
mounted individually, or in twin cylinder installation for heavier
loads. It is also possible to install more then two AV actuators in
multiple applications.
The AV hatch lifters do not require any maintenance, are easy to
install, and are made of materials resistant to corrosion.

INSTALLATION
• The following equation will help you to calculate the
maximum strength (Fmax) required from the hatch lifter to open
your hatch, knowing the dimensions and weight of the hatch and
the position of the mounting brackets.
Fmax = P x d x L
2 b a
P = weight of the hatch in Newton
c, a, b = dimensions in metres indicated in Fig. 3 and Fig. 4
L = hatch lifter length when in closed position
Warning: Maximum load (Fmax) for the AV actuator in single
installation: 1200 N, in dual installation: 2400 N.
NOTE: WHEN THE LOAD EXCEEDS 2400 N (240 kg) IT IS POSSIBLE TO
INSTALL MORE THAN TWO AV ACTUATORS.
