  • Patent number: 5150557
    Abstract: A handset shoring system for supporting elevated concrete slabs and beams which can readily be integrated into other systems but has benefits of lightweight strength, field adaptability, and an infinitely variable range of sizes for optimum usage. Laminated veneer lumber posts with force-fit steel end cap provide the shoring legs having screw jack and U-heads thereon. An adjustable beam form can also be mounted atop the shoring system.

  • Patent number: 4790113
    Abstract: An adjustable depth truss for a flying table comprised of an upper and lower chord held in spaced relationship to each other by diagonal supports attached by connectors received within holes spaced along the length of the chords. The connectors are selectively positionable in the holes to change the angle at which the diagonals are mounted to the chords, thereby varying the distance between the chords and adjusting the depth of the truss.

  • Patent number: 4673060
    Abstract: A foldable scaffold which can be erected to the side of a scaffold anchor having a horizontal member pivotally mounted at one end to the scaffold anchor and a support member pivotally mounted at one end to the horizontal member and the other end releasably mounted on the support anchor. A pin is provided for selectively holding the horizontal member in a first horizontal position and for releasing the horizontal member from that first horizontal position to allow the horizontal member and the support member to pivot to a second position in which the horizontal and support members are closely approximated with the scaffold anchor. If, for instance, the scaffold anchor is a gangform, the disassembly, storage, transport and re-assembly of the gangform is greatly facilitated by the fact that the scaffold is folded and re-erected by merely inserting two pins into the horizontal member and support member.
