Patent ID: 8388033

Claim:
A modular lifting beam comprising: a first plate having a first end, an opposing second end, a top edge and an opposing bottom edge, and an inside surface and an outside surface; a second plate in substantially parallel relation to said first plate and having a first end, an opposing second end, a top edge and an opposing bottom edge, and an inside surface and an outside surface; a plurality of spacers, each of said spacers attached at a first end to the first plate and at an opposing second end to the second plate such that the first plate and the second plate are held in spaced-apart relation; a first pair of upper lugs each having a hole extending from an upper surface of the lug to a lower surface thereof, at least one of said lugs attached to the first end of the first plate proximate the top edge of the first plate, said lug configured such that at least a portion of the hole extends beyond the first end of the first plate; a first pair of lower lugs each having a hole extending from an upper surface of the lug to a lower surface thereof, at least one of said lugs attached to the first end of the first plate proximate the bottom edge of the first plate, said lug configured such that at least a portion of the hole extends beyond the first end of the first plate; a second pair of upper lugs each having a hole extending from an upper surface of the lug to a lower surface thereof, at least one of said lugs attached to the second end of the first plate proximate the top edge of the first plate and vertically displaced from the first pair of upper lugs, said lug configured such that at least a portion of the hole extends beyond the second end of the first plate; a second pair of lower lugs each having a hole extending from an upper surface of the lug to a lower surface thereof, at least one of said lugs attached to the second end of the first plate proximate the bottom edge of the first plate and vertically displaced from the first pair of lower lugs, said lug configured such that at least a portion of the hole extends beyond the second end of the first plate.
