The 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 AV hatch lifter can be mounted individually, or in twin cylinder installation for heavier loads.

• Maximum load for single installations: 1200N (120 kg – 265 lbs)

• Maximum load for dual installations: 2400N (240 kg – 529 lbs)

• Maximum load is not to be exceeded.

• Supplied with all mounting hardware.

• Stainless steel telescopic ram for manual opening in case of emergency.

• Circuit breaker to stop accidental overloading of the system and electronic stop at closed or full open position.

• IP 65 protection

• Speed: 25mm/sec no load applied, 17 mm/sec maximum load

• Current absorption in single installations: 10A at 12V, 5A at 24V

• Current absorption in dual installations: 20A at 12V, 10A at 24V

• AV 12VDC models are Ignition Protected. UL1500 – ISO8846 approved.





• 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.


Maximum load (Fmax):

1200 N (120 kg – 265 lbs) single installation, pushing only

2400 N (240 kg – 530 lbs) dual installation pushing only

Note: when the load exceeds 2400 N (240 kg – 530 lbs), it is possible to install more then two AV actuators. Please, contact our Technical Service for the proper electrical configuration
