Abstract

Abstract A portable pallet rack is described and includes a horizontally disposed frame having supporting wheels provided thereon. The rack is designed to accommodate either four or six stacks of pallets thereon. The pallet rack is moved beneath the underside of the trailer floor and is vertically movably mounted with respect to the trailer by means of a pair of winch assemblies. The winch assemblies are quickly and easily adjustably mounted at the underside of the floor without any welding or drilling being required. The fact that the winch assemblies are quickly and easily adjustably mounted at the underside of the floor permits the pallet rack to be longitudinally shifted to place the weight thereof either on the rear axle of the trailer or on the truck.

Claim 1
Independent Claim 205 words
In combination: a wheeled trailer having a floor means spaced above ground level, said floor means having an underside, a wheeled pallet support means adapted to support a plurality of stacked pallets thereon beneath the underside of said floor means, and at least a pair of spaced apart belt and winch means operatively interconnecting said pallet support means and said trailer for selectively raising and lowering said pallet support means and the pallets thereon with respect to said floor means, each of said belt and winch means comprising: a first bracket means operatively secured to said trailer at one side thereof beneath said floor means, an elongated flexible strap means secured at one end thereof to said first bracket means and extending downwardly therefrom and thence beneath said pallet support means towards the other side of said trailer, a second bracket means operatively secured to said trailer at the other side thereof beneath said floor means, and a winch means operatively secured to said second bracket means adapted to engage the other end of said strap means whereby said strap means may be selectively rolled upon said winch means to raise said pallet support means or selectively unrolled therefrom to lower said pallet support means.
Claim 2
Dependent Claim 205 words
In combination: a wheeled trailer having a floor means spaced above ground level, said floor means having an underside, a wheeled pallet support means adapted to support a plurality of stacked pallets thereon beneath the underside of said floor means, and at least a pair of spaced apart belt and winch means operatively interconnecting said pallet support means and said trailer for selectively raising and lowering said pallet support means and the pallets thereon with respect to said floor means, each of said belt and winch means comprising: a first bracket means operatively secured to said trailer at one side thereof beneath said floor means, an elongated flexible strap means secured at one end thereof to said first bracket means and extending downwardly therefrom and thence beneath said pallet support means towards the other side of said trailer, a second bracket means operatively secured to said trailer at the other side thereof beneath said floor means, and a winch means operatively secured to said second bracket means adapted to engage the other end of said strap means whereby said strap means may be selectively rolled upon said winch means to raise said pallet support means or selectively unrolled therefrom to lower said pallet support means.
Claim 3
Dependent Claim 29 words
