SPECIFICATIONS

Description

FA5A winches are air powered, planetary geared units designed
for lifting and pulling applications. FA5A winches are supplied
with either an internal automatic disc brake, a manual or
automatic externally mounted drum band brake, or a
combination of both.
The output from an externally mounted piston air motor is
transmitted through a coupling and shaft to the planetary
reduction gear assembly.
The output from the planetary reduction gear assembly is
connected to the wire rope drum through the output shaft.
The disc brake attaches to the outboard upright opposite the
motor end and is connected to the intermediate sun gear through
the brake shaft. The disc brake is automatically applied when the
winch is in the neutral or operated in the haul-in positions;
disengaged when the winch is operated in the payout direction.

During winch operation a sprag type clutch in the disc brake
allows drum rotation in the haul-in direction with the disc brake
engaged. This ensures the brake will respond quickly to hold the
load when winch operation stops. Operation of the winch in the
payout direction directs pressurized air to the disc brake
diaphragm to overcome spring tension and release the brake.
When the payout operation is complete the air is vented and the
brake is automatically applied.
The drum band brake operates by applying a friction force
between the drum band and the winch drum. The manual brake
requires an operator to engage and disengage the brake using a
lever located near the air motor end of the winch. The automatic
drum band brake operation is similar to the disc brake with the
following exception: the automatic drum band brake fully
disengages in both the haul-in and payout directions.
