Description of Operation

FA5 winches are air powered, planetary geared units designed for lifting and pulling applications. FA5 winches are available with either an internal automatic disc brake, a manual or automatic 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 planetary reduction gear assembly is connected to the wire rope drum through the output shaft.

FA5 winches can be provided with an optional disc brake assembly consisting of friction plates splined to a hub which in turn is connected to the drive shaft from the air motor. Brake friction plates are clamped to the drum shaft through a spring applied piston. The brake remains applied until the winch control valve is operated and winch payout or haul-in occurs. Air is introduced into the brake piston chamber, which is formed between brake piston and brake housing, causing the brake piston to react, compressing brake springs and releasing friction plates allowing motor shaft to rotate. A power failure or sudden loss of air will immediately cause the spring applied brake to engage.

The drum band brake operates by applying a friction force between drum brake band and winch drum. The manual brake requires an operator to engage and disengage brake using a lever located on top of brake band. The automatic drum band brake operation is similar to disc brake operation; they are both fully disengaged in the haul-in and payout direction.
