3.1.1 GENERAL
The AmClyde Model TW-425/250 is a wire rope traction winch designed and manufactured
for use on a deepwater pipelay vessel. The winch may be converted for the use of two
different wire rope diameters by means of removable laggings.
The winch is powered by two electric drive motors driving through a two speed gearbox.
The Model TW-425/250 is complete with the following equipment and specifications:
3.1.2 TWIN DRUM TRACTION WINCH
The Traction Winch is equipped with two (2) drums which are powered by a common
pinion. The drums are heavy duty combination cast and fabricated steel structures. The
drums are provided with interchangeable laggings machined to provide a minimum 20:1
D/d ratio with the wire rope. The drums are mounted on fixed, non-rotating drumshafts
and rotate on anti-friction roller bearings. The drumshafts are solidly clamped to the winch
frame and act as structural members. A gear is mounted on the drum flange of each drum
which in turn meshes with the pinion mounted on the drive shaft.
3.1.3 TRACTION WINCH BRAKES
A brake flange is integral with each Traction Winch Drum. Each brake flange is equipped
with an external contracting band type brake. The brake bands are fitted with nonasbestos
lining. The brakes are spring-set and air released in operation.

3.1.5 DRIVE ARRANGEMENT
The drive from the gearbox to the Traction Winch is through a single drive shaft. The drive
shaft distributes power to the Traction Winch through a pinion which drives both drum
gears.
3.1.6 MAINTENANCE DOG
A dog is provided on the Traction Winch on the TW-425/250. The dog acts against
pockets in the flange of the rear drum of the Traction Winch. The dog is manually
engaged and released.
