Safety Information

  • For safe operation all winches should be installed with the ratchet pawl on top of the ratchet wheel so that the pawl drops into the ratchet wheel by gravity.
  • Use a winch bar when tightening or loosening winches.
  • Never let go a winch bar without checking that the pawl has fully engaged a ratchet wheel tooth.


On and after January 1, 2010, a person shall not use a tiedown or a component of a tiedown to secure cargo to a vehicle unless it is marked by the manufacturer with respect to its working load limit.
