  • Hinged bows used to support tarpaulin on trailers
    Patent number: 5211441
    Abstract: Tarpaulin support bows are provided on a vehicle trailer or bed for supporting the tarpaulin which covers the material being hauled on the vehicle. The support bows are hingedly mounted so they are able to move when they are contacted by a material loading bucket or compacted material. The movement of the support bows reduces the opportunity for damage or breakage of the bows or the vehicle sideboards to which the bows are mounted.
