In some applications, there is a need to restrain the equipment from rotating in the reverse direction. If a clutch or brake is too complicated for the system, CCA can offer a simple solution that keeps things running in the right direction.
CCA has developed an integrated feature available in most couplings that will allow equipment to turn in its normal direction while restraining the equipment from turning backwards. The coupling uses centrifugally actuated ratcheting pawls that extend and retract at specifically designed rotating speeds. At the lower speed limits, the extended pawls contact a floor-mounted backstop. If the rotating assembly attempts to rotate backwards, the pawls lock into place and keep the equipment from moving.
