ABSTRACT:
A winch for securing the tie down straps used to restrain cargo transported on a flatbed vehicle. The winch includes a rigid frame having a rotatable winch drum on which the strap may be wound. A ratchet wheel on the end of the winch drum includes two sets of teeth which are axially offset and circumferentially staggered relative to each other. A pawl for locking the ratchet wheel has two similarly offset and staggered sets of teeth. The teeth of the pawl and ratchet wheel interlock at locations that are both axially and circumferentially offset to distribute the stresses and enhance the structural strength of the winch.
