Locking Headboard Assembly
3
General description - Locking mechanism continued -
The trip line connects to plungers that compress springs
when the trip line is pulled. The energized springs operate the control link. Once the sail is hoisted so the pawls
are just above the pockets, the locking procedure starts. When pulling the trip line and lowering the sail, the
energized control link levers the pawls to find the pockets. Continuing to lower the car engages the pockets.
Installation, Proximity sensor
The locking
car has provisions in the slider bearings for
a magnet so that proximity sensors can be
used at full hoist and at the locking car reef
locations. Any of the slider bearings can
house the magnet allowing for flexibility of the
sensor mount location. A light press-fit holds
the magnet in place. Use a block of wood
and mallet to tap the magnet in place. In use,
a light indicates that the sail height is in the
correct position with locking car pawls raised
higher than the lock track pockets. Pulling
the trip line while the car is lowered energizes
the pawls to engage into the locked position.
Alternatively use marks on the halyard.
Note:
The sensor magnet is supplied by
Harken. The proximity sensor is not supplied.
