  • Patent number: 6886662
    Abstract: A scaffold support system having an adjustable-width hanger. A vertical leg may support a foot upon which rests a deck, providing a working surface during building construction or modification. A lateral beam rests on a support structure forming part of the wall of a building with the vertical leg securing to the lateral beam at a plurality of points. A stop secured to the lateral beam to capture a support structure between itself and the vertical leg. The stop may be adjustable along the lateral beam to accommodate support structures of varying widths. An operator may insert the hanger from inside a building and pass the coupler through a gap between a frieze block and a top plate, presenting the coupler for securement to the vertical leg. A catch may slide along the foot into and out of engagement with an edge of the deck to prevent rotation of the deck.

  • Patent number: 6845845
    Abstract: A water recreation dock for providing access into and out of the water comprising a main deck platform carried by a dock frame. A stationary platform forms a first part of the main deck platform which is supported above the water on the dock frame. A movable platform forms a second part of the main deck platform which has a raised position and a lowered position. A landing section and a walkway section are included in the movable platform. In the raised position, the landing section and walkway section are located generally in a common horizontal plane with the stationary platform above the water. In the lowered position, the landing section is submerged and the walkway section is partially submerged as extending from the stationary platform to the landing section to provide access into and out of the water.

  • Patent number: 6840350
    Abstract: An adjustable universal safety scaffold and walkboard ladder holder that absolutely prevents scaffold collapse or dis-attachment from a construction project and absolutely prevents a ladder placed against a walkboard from slipping sideways. Vertical supports can attach attach top and bottom to the building or work under construction. Hold brackets that can be raised or lowered slide up and down the vertical supports. A walkway sits on the hold brackets and is positively held in place by pins. A ladder can be optionally leaned against the walkboard and secured by additional stay bolts into the walkboard to prevent horizontal slipping.

  • Patent number: 6827181
    Abstract: A collapsible and adjustable scaffold unit includes a base frame structure and an upper frame structure. Leg members on the base frame structure are independently adjustable in length and include pivoting feet to compensate for grade change and uneven terrain. The upper frame structure includes a vertical post which removably attaches to the base frame structure to accommodate adjustably positionable brace arms. The brace arms support planks spanning between two or more of the scaffold units to provide an uninterrupted walkway and a continuous workbench above the walkway. Adjusted movement of the brace arms along the vertical post, throughout a range of locked positions, allows the height of the walkway and workbench to be selectively varied according to the needs of the user.

  • Patent number: 6820722
    Abstract: A device for erecting roof comprises a portable platform of a size and weight easily lifted and manipulated by a single worker. The platform is configured to fit over the upper ends of the chords of a truss that has already been secured in place so that it can support a worker. By using a pair of the devices, the worker can move from truss to truss, from one end of the roof to the other. The worker moves the device that is not currently in use from one truss to the truss that he has just finished securing in place, and then steps from the device currently in use onto the other device so that the worker is supported on the newly secured truss, in position to guide a new truss into position so that it can be secured. This process is repeated until all trusses have been secured.

  • Patent number: 6349441
    Abstract: A mobile access bridge provides access to the doors and the exterior surface of an aircraft fuselage in the final stages of construction, assembly, and outfitting. The access bridge includes catwalks preferably arranged at several levels, in pairs on opposite sides of the aircraft. The bridge further includes bridge supports that each have an arched inverted U-shape. The bridge supports are connected to and carry the catwalks, and respectively arch over the top of the aircraft fuselage. The bridge may be made up of a number of bridge segments that are coupled together as needed by coupling units. The entire bridge or each individual bridge segment is lifted at a lifting fixture by an overhead crane or lifting cable, is then moved into position, and then lowered onto the aircraft fuselage.
