FEATURES & INFORMATION
Andersen Winches
ANDERSEN STAINLESS
STEEL WINCHES
™
Enduring Strength,
Everlasting Finish
Every Andersen winch is made with the care and craftsmanship that
come from more than 昀椀fty years of experience. Andersen winches are
built to last, to retain their exceptional 昀椀nish and to deliver season after
season of reliable performance and sailing pleasure to their owner
through the years.
Materials
Andersen 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 昀椀nal form. The
resulting construction is lightweight, yet sti昀昀 and unyielding.
Drive shafts are in grade 329 duplex stainless steel. Pawls are cut from a cold pressed
pro昀椀le in grade 316 stainless steel and are virtually unbreakable.
The upper centre stems of Andersen winches are manufactured from aluminium bronze
for ultimate durability. The combination of materials and design contribute to a lightweight,
rigid 昀椀nal assembly that enhances the mechanical e昀케ciency of the winch.
Features
Andersen 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 minimises 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 昀椀nish for grip.
Stainless steel roller bearings and ball bearings carry the highest drum loads to the
centre stem of the winch, minimising e昀케ciency losses due to friction.
The self-tailing arm can be rotated incrementally 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.
