Description
FA2A winches are air powered, planetary geared units designed for
lifting and pulling applications. FA2A 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 handle 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.
