Lenco Marine
Due to the many different variables involved
with the numerous applications for Lenco
hatch lifts, installation is never the same. Here
are some general guidelines that can be of
assistance:
• The actuator is most powerful when it is
installed vertically at 90 degrees.
• Lifting capabilities decrease the closer the
upper or lower mount is located to the hinge.
• The further from a vertical position the less
lifting capability. When retracted,
Do Not
position hatch lift at an angle less than
45 degrees.
• Dual actuator systems are recommended for
hatches over 500 pounds (226.79 kg) of force.
• Lenco hatch lifts are designed around a ball
screw that spins freely when hatch is fully
open or closed.
• For installation, it is important that the hatch
lift is able to disengage itself at the fully
retracted position.
• The ram must be allowed to free spin at both
ends of its stroke or it will continue to push
or pull against any resistance potentially
damaging the hatch lift ot the hatch itself.
• Failure to make accurate measure could cause
damage to hatch lift or the hatch itself.
• Lenco hatch lifts are fully submersible and will
not drift.
• Lenco hatch lifts are offered in both 12 and
24 volts.
OPERATION
The function of the Lenco Hatch Lift system is
simple. Since the hatch lift is based around a ball
screw it is able to push a heavy load and remain
at a constant position. To raise a load, extend
the hatch lift by pressing on the upper part of
the switch. To lower a load, retract the hatch lift
by pressing the lower part of the switch.
In case of power failure, Lenco hatch lifts are
supplied with two clevis pins at the mounting
brackets. To pull this pin out while the hatch is
closed, you must rig it to a point outside of
the hatch.
S = Short. All part numbers ending in S have
the same stroke but in a 4" (10.16 cm)
shorter length.
