PREPARATION OF MOUNTING
Standard units will accommodate deck thickness up to 100mm (4”). Extra clearance
models are available to accommodate deck thickness in the range of 100mm to 150mm
(6”).
It should be noted that keeping the thickness to no more than 100mm (4”) and 150mm
(6”) respectively, will considerably enhance serviceability. This will allow access to the
gearbox mounting bolts, allowing the gearbox to be removed as a sealed unit, without
dismantling the top works.
** IMPORTANT **
1.
IT IS IMPERATIVE THAT THE DESIGNER/INSTALLER ENSURES THAT THE
DECK AND UNDERDECK PAD ARE OF SUFFICIENT THICKNESS AND
STRUCTURAL STRENGTH TO SUSTAIN THE LOADS CAPABLE OF BEING
IMPOSED ON OR BY THE WINDLASS. THE UNDERDECK PAD SHOULD
SPREAD THE LOADS AS WIDELY AS POSSIBLE AND IF USE CAN BE MADE
OF A BULKHEAD OR CROSS MEMBER TO PROVIDE STIFFENING, THIS
SHOULD BE DONE.
2.
IT IS VERY IMPORTANT THAT THE ABOVE DECK PAD TOP SURFACE OR
DECK AREA COVERED BY THE GASKET SUPPLIED, AND THE UNDERDECK
AREA AGAINST WHICH THE LOAD WASHERS SEAT, ARE SMOOTH, FLAT
AND GENERALLY PARALLEL.
3. The gasket item 22 supplied with the Windlass can be used for accurately spotting
the mounting holes and marking the cut outs. After spotting, bore the necessary
holes. These must be drilled parallel to each other and square to the mounting
face.
DON’T SPOT THROUGH THE GASKET WITH THE DRILL. THIS WILL DAMAGE
THE
GASKET.
NOTE: For boats of steel or aluminium construction,
it is very important that the
deckplate is insulated from the deck with the non conductive gasket provided that the
mounting studs pass through insulators and that the underdeck fixings are insulated
from the deck. It is also important that the anchor and chain is insulated from the hull,
including rubber lining, the chain locker and insulating the fixing for the end of the chain
to the hull.
Without these precautions severe electrolysis can occur.
It is not necessary to separately earth the Windlass, as the electric motor is of the
isolated earth type.
