The claimed invention relates to a folding utility scaffold that greatly reduces the space requirement for shipment when the utility scaffold is in the folded configuration while maintaining or increasing stability. The scaffold includes first and second ladder frames and a hinge assembly interconnecting the ladder frames. The scaffold comprises first and second ladder frames and a hinge assembly interconnecting the ladder frames. The hinge assembly enables movement of the scaffold between an unfolded configuration in which the ladder frames are spaced apart and a folded configuration in which the ladder frames are disposed side by side, i.e., with the ladder frames touching. The ladder frame and hinge assembly are designed to avoid interference between components of the hinge assembly and components of the ladder frame in the folded configuration so that the ladder frames can be disposed in side-by-side relation in the folded configuration.

A pair of dollies for storing and transporting scaffold frames is disclosed. Each dolly is made up of two identical dolly members containing a top plate, bottom plate, two side plates and a front and back plate. Communicating holes are inserted along the length of the top and bottom plates. The side plates of each dolly member has semi-circular cut outs on the top edges which correspond with the holes in the top and bottom plates. The end holes at the front and back of each dolly member have tubes permanently inserted to receive a typical scaffold 8 inch swivel caster wheel with brake. Scaffold frame legs are inserted into the remaining holes in the top and bottom plates of the dollies. The bottom cross member of each scaffold frame sits on the semi-circular cut outs on the top edges of the side plates. This device can be used for storage or transportation of scaffold frames.

A shelf apparatus configured for temporary attachment to a ladder deployed in a working position includes a planar tray supported at its inboard end by a rung or top plate of the ladder, left and right support arms pivotably attached to opposite sides of the tray near its inboard end, a rigid linkage coupling the tray to the left and right support arms, and an adjustable clamping mechanism for clamping the tray to the rung or top plate. In use with a straight ladder, the tray is horizontally suspended under the inclined frame of the deployed ladder, the support arms are raised to rest against the inclined rails of the ladder above the tray, the rigid linkage vertically supports the tray from the support arms, and the clamping mechanism secures the tray to the rung.

The apparatus may include a ridge member, a first arm rotatably coupled to the ridge member and extending outward, relative to the ridge member, in a first plane angled relative to a first pitch of a roof structure. Also, the apparatus may include a second arm rotatably coupled to the ridge member and extending outward, relative to the ridge member, in a second plane angled relative to a second pitch of the roof structure. The ridge member may be positioned at an apex between the first pitch and the second pitch along a ridge of the roof structure. Further, materials for installation may be placed on at least one of the first arm and the second arm positioned between the roof structure and the materials. Additionally, the apparatus may include a load arm coupled at each respective end portion of the first arm and the second arm.

Work platform systems and related methods of assembly and use are disclosed herein. In one exemplary embodiment, a method of installing a work platform system into an internal cavity of a structure includes supporting a first platform portion at a first location, and adding a plurality of additional platform portions to the first platform portion, where successive ones of the additional platform portions are respectively positioned at respective locations that are successively farther outward away from the first platform portion. The method further includes coupling the additional platform portions to one or more other locations, and detaching the additional platform portions from one another. The method additionally includes lowering or raising one or more of the first and additional platform portions to one or more additional levels below or above the first level, where the work platform system includes the first and additional platform portions.

A method for providing and assembling scaffolding units, each of which will be assembled from individual scaffolding components (of a scaffolding system) for constructing an industrial plant, in particular a petroleum refinery, comprising the following steps: Providing a 3D construction plan of the industrial plant; Constructing schedule for the industrial plant in order of occurrence, Selecting and drawing of scaffolding units to be used in the individual sections or phases of construction of the industrial plant in the 3D construction plan; Specifying the erection time required to erect the scaffolding unit; Specifying the dismantling time required to dismantle unit; Dividing the construction schedule into time intervals; Calculating for every single time interval, while taking into consideration the erection and dismantling times of the scaffolding units, the respective number of scaffolding components of identical design which are used simultaneously; Determining the maximum number of scaffolding components of the design which are used simultaneously across all time intervals; Providing the maximum number of scaffolding components of design alone and including a defined number of a buffer of scaffolding components of design; assembly of the scaffolding units to be used in a respective phase of construction from the scaffolding components each required for this purpose on-site at a point in time chosen in dependency of the specified erection time each at the latest prior to a start of construction in the respective section of construction specified in the construction schedule.

An apparatus includes a first platform, a second platform disposed above the first platform, a scaffolding connecting the first and second platforms including an upper support beam, a middle support beam, and a lower support beam, and a cable attached to the upper support beam. The lower support beam supports the first platform. The middle support beam supports the second platform. The upper support beam is disposed above the second platform.

The Tool Organizer works in union with a scaffold. The Tool Organizer apparatus of a condensed step design having a plurality of cavities, depressions, chambers, and slots for tools and supplies, on each planner surface, wherein a rim encompasses the center plane and two structural reinforce cylinder sleeve mounts, located on the same center axis protrude perpendicular above the center plane and below the center plane with a fastener on each structural reinforce cylinder sleeve mount, which mount upon scaffold top joint round tubes. Therefore, the craftsman's tools are stowed on the Tool Organizer within reach with an accessible solid workspace.

A scaffolding system can include a first platform and a second platform adjustably connected to a plurality of tower extensions. Fixing members coupled to the plurality of tower extensions may fix a separation distance between the first platform and the second platform. One or more dimensions of the first platform and one or more dimensions of the second platform may be adjustable. A position of the first and second platforms along the plurality of tower extensions may be manually adjustable. An extendable wall may be connected to outer edges of the first and second platforms.
