Devices for anchoring objects to structural elements such as rafter beams and other similar objects are disclosed. Such anchoring devices include coupling devices configured to grasp beams nondestructively and may include multiple coupling devices to enable supporting extended structures too large or heavy to be supported by a single anchoring point in areas where hanging or supporting objects might otherwise be difficult.

A scaffolding assembly adapted to be releasably attached to an elongate support member such as an overhead pipe. The scaffolding assembly has a split collar and a platform assembly adapted to be releasably attached to the split collar. The split collar comprises at least two segments which can encircle the pipe and be secured to one another. The platform assembly which includes a platform deck has a connector formation which extends laterally outwardly from the deck to an extent that it can engage a receiving formation on the collar assembly and thereby attach the platform assembly to the collar assembly.

A truss support system (10) comprises a support pole (12), a connector (14) located at one end of the support pole (12) and for connecting to a scaffold pole (16), a first extendable arm (18) connected at one end to the support pole (12) and extending away from the support pole (12), and a first fixing plate (20) connected to the first extendable arm 18 at the opposite end to the support pole (12). The truss support system (10) is also provided with a second extendable arm connected at one end to the support pole (12) and extending away from the support pole (12), and a second fixing plate connected to the second extendable arm at the opposite end to the support pole (12).

A free-standing demountable window safety assembly adapted to rest, in use, on the floor inside a room containing a window opening in a wall, and against the wall containing the window, without engaging with the window opening, said assembly comprising: —⋅(i) at least two feet (125, 126) adapted to engage with the room floor⋅(ii) at least two arms (121A, 121B, 135A, 135B) adapted to engage with the room wall adjacent to but spaced away from the window opening; ⋅(iii) at least two side portions (125, 123A, 135A, 133A) each supporting an arm; ⋅(iv) at least one linking member (111A, 111C) adapted to link opposing side portions or opposing feet in a substantially rigid fashion. The invention also includes methods of manufacturing and using such safety assemblies.

A method and apparatus for assembling a hanging scaffold system within the aft pressure bulkhead area of an aircraft to provide access to the pressure dome without contacting the pressure dome. The hanging scaffold system comprises a group of horizontal supports to support at least one floorboard. A group of vertical supports is connected to and extends perpendicularly from the group of horizontal supports. A clamping device is attached to each vertical support of the group of vertical supports and further engages an attachment point on an internal structure of an aircraft.

A panel is disclosed which is suitable for installation to form a platform or part of a platform in a void of a building structure. The panel is operable to extend between a first support member and a second support member both of which extend across at least a portion of the void. The panel has: a deck component with: a first end and a second end opposite the first end; a pair of opposed, substantially straight sides each extending from the first end to the second end; and a substantially planar surface portion which extends: between the opposed sides at the first end, and from the first end at least part of the way, but not necessarily all the way, to the second end; and one or more first engaging formations at the first end of the deck component and operable to engage with the first support member to support the deck component relative to the first support member, and one or more second engaging formations at the second end of the deck component and operable to engage with the second support member to support the deck component relative to the second support member. At least one out of the first and second engaging formation(s) is/are configured to support the relevant end of the deck component relative to the relevant support member from approximately directly vertically beneath, and/or from approximately within vertical planes containing, each of the straight sides of the deck component.

The shingle installation jack devices may be mounted once at a first roof level, providing support for the walk board. When installation or repair of the shingles is complete at the first level of the roof, the shingle installation jack devices may be operated in tandem to raise the level of the walk board to a second level of the roof. Shingle installation and/or repair may then be carried out at this second roof level without the need to re-mount the walk board supports at the second level. The shingle installation jack devices may also be run in reverse to lower the walk boards. The shingle installation device includes a frame and utilizes a winch motor to adjust the effective length of a cable and thus adjustably raise or lower the walk boards to any desired roof level.

A walkway system includes brackets that are connectable to vertical frame members and supportable by horizontal frame members. Walkway support members include lips that engage with the brackets, horizontally-oriented portions that support a walkway member, and vertically-oriented portions that contact the building to stabilize the walkway member.

A plank scaffold system and, more particularly, to a ladder-based vertically-adjustable plank scaffold system. The system may have a pair of ladders, a wall standoff mounted at the top of each of the ladders, a crane support mounted at the top of each of the ladders, a vertical guide bar and roller system to keep it from swinging on the cables, and a horizontal platform suspended on cables below the crane supports, the platform having a pair of cable winches mounted thereon for varying the elevation of the platform. Instead of ladders, tower scaffolds or stage towers may be used on each side to support the vertically-adjustable plank.
