Andersen 34 St Fs - 2-Speed Self-Tailing Manual Winch - Full Stainless Steel
you take pride in having your yacht look its best, ANDERSEN's Full
Stainless Self-Tailing Winch creates the dock-stopping appeal you
desire. It combines all the convenience and power of ANDERSEN's
self-tailing winch with a stunning all stainless steel look.
top to bottom the drive shaft stripper arm, self-tailing jaws, drum and
upper & lower trim rings are manufactured in highest quality and
beautifully polished grade 316 stainless steel. The dramatic result is a
highly reflective winch that becomes a highlight of the boat and a true
reflection of your yachting pride. We like to say, “Full Stainless –
Beyond Good Looks.”
As with all ANDERSEN Winches™, our Full
Stainless Self-Tailing winch features the exclusive stainless steel
Power Rib™ drum for maximum power and extended line life. This model
also uses our exclusive self-tailing device that automatically
accommodates a wide range of different line sizes.
winch drums are produced from grade 316L stainless steel, cold formed
in stages during manufacture to further increase strength and hardness
as it takes its final form. The resulting construction is lightweight,
yet stiff and unyielding.
Drive shafts are in grade 329 duplex
stainless steel. Pawls are cut from a cold pressed profile in grade 316
stainless steel and are virtually unbreakable.
The upper center
stems are manufactured from aluminum bronze for ultimate durability. The
combination of materials and design contribute to a lightweight, rigid
final assembly that enhances. the mechanical efficiency of the winch.
Andersen winces are of similar weight to winches with aluminum drums,
but are far more durable.
Winches© feature the Power Rib™. Unlike other winches with abrasive
drum surfaces, ANDERSEN winch drums have vertical ribs running up the
surface. This combined with the smooth polished stainless steel gives a
maximum grip and minimum wear on ropes, reducing the replacements costs
of sheets and halyards. What's more, the Power Rib principle simply
makes sailing more pleasurable. Fewer turns on the winch make tacking
easier. Sheets can be gently eased out without harsh snatching and the
risks of overrides and jammed sheets are significantly reduced. The grip
provided by the ribs will remain the same year after year, unlike many
other winches with an abrasive or sandpaper-like surface. Such surfaces
have a tendency to wear down both ropes and themselves.
Power Ratio is the mechanical advantage of the winch and is calculated as follows:
length of handle x gear ratio radius of drum
pull of the winch is based on the Power Ratio and not just on the
physical size of the winch or the diameter of the drum. The Power Ratio
is used to determine the load the winch may handle as follows:pull of
handle (kg x Power Ratio = pull of winch (kg).
This means that by
applying a load of 10kg, using a 10" standard handle, on a Power Ratio
40:1 winch, the winch can pull 400kg, assuming that the winch is 100%
efficient. This is not possible in practice as the efficiency is reduced
by internal mechanical friction losses.
winch drums incorporate the distinctive Power Rib which ensures a
controlled grip on the line at all times, whether trimming or easing.
The highly polished stainless steel surface minimizes vertical friction
and allows the loaded rope turns to slide easily upward as the drum
rotates, without the shuddering and excessive rope wear seen on winches
that rely on a rough surface finish for grip.
roller bearings and ball bearings carry the highest drum loads to the
center stem of the winch, minimizing efficiency losses due to friction.
self tailing arm can be rotated through 360 degrees for optimum
positioning (40ST and larger). Stainless steel self-tailing jaws adjust
automatically to suit various rope sizes.
Andersen winches are
designed for simple, straightforward installation and maintenance.
Servicing is only required every two years or so, under normal use.
