A work platform includes a plank which telescopes to a desired width. The work platform includes a first leg assembly rotatably attached adjacent to a first end of the plank. The work platform includes a second leg assembly rotatably attached adjacent to a second end of the plank. The plank is in an open position when the plank is supported by the first leg assembly and second leg assembly and the first leg assembly and second leg assembly form an angle greater than 25 degrees with the plank. The plank is in a closed position when the first leg assembly and second leg assembly are adjacent to and in parallel with the plank. A method for using a work platform. A method for producing a work platform.

Disclosed is an arrangement including a staircase as well as walkway systems. The staircase includes a transitional member, and the walkways incorporate grate supports in order to facilitate the connection to adjacent structures. The arrangement also utilizes angled members which are configured with a reinforced flange existing in a dimension that has higher load requirements than the other flange. A novel step configuration is also disclosed.

A scaffold includes a U-profile beam having an outwardly-open U-profile in which a scaffold platform is releasably hooked by mounting hooks. The U-profile beam has a perpendicular wall delimiting the U-profile and a guiding and fastening groove delimited by inwardly-extending groove reach-behind protrusions delimiting a locking space for releasably locking a locking element reaching behind the protrusions. An anti-lift-out and support element has an anti-lift-out element extending over the hooks to prevent lifting out. A support element fixed to the anti-lift-out element extends perpendicularly from the anti-lift-out element to a support element end for supporting the support element on the wall. The anti-lift-out element has a through-opening designed so that the fastening element moves the locking element toward the fastening element longitudinal axis and perpendicularly to the groove through the through-opening. A method secures scaffold platform mounting hooks against lifting out from a U-profile beam using an anti-lift-out device.

A configurable scaffolding system is configured to facilitate simplified, reconfigurable access to a plurality of horticulture racks. With use of the configurable scaffolding system, operator convenience and safety are improved, and increased plant density in horticultural applications can be achieved.

The present application provides an effective cooperation of scaffold planks and ledger members of a scaffold system to provide a work platform that is adaptable to different requirements and configurations. In one embodiment a rail portion of a scaffold plank is received in an upwardly opening U-shaped cavity of a ledger. In this way a portion of the work surface over laps with the ledger.

An assembly for installation, repair, or maintenance of balcony-mounted displays. The assembly may include a straddling component or frame, an anchoring assembly for selectively fixing one end of the straddling component in a desired location along the balcony, and a person-holding structure suspended from the balcony by another end of the straddling component. The straddling component may include forward vertical supports extending from the person-holding structure, horizontal supports attached to the forward vertical supports, and aftward vertical supports attached to the horizontal supports. Transport wheels may be rotatably attached to the aftward vertical supports, for rollable relocation of the platform relative to the balcony. The anchoring assembly may include both forward and aftward extension pieces attached to the aftward vertical supports and selectively adjusted to cooperatively fix the aftward vertical supports between a balcony wall and a heel-kick surface below the balcony seating.

A scaffold ledger providing a raised support surface of the elongate structural member with the opposed ledger heads being downwardly and outwardly offset. Each ledger head includes cover flaps that extend the raised support surface above the ledger heads in a cover position. The scaffold ledger cooperates with scaffold posts and scaffold planks to allow for a continuous work platform above an intermediate scaffold support post and/or across supporting ledgers.

A platform system includes a support structure of variable length; a platform mountable on the support structure; and a plurality of platform supports for supporting the platform. At least one of the platform supports is slideably mounted on the support structure such that it is slideable with respect to the support structure. At least one of the platform supports includes a spacing element, which extends between that platform support and an adjacent one of the platform supports and engages the adjacent platform support, such that the maximum spacing between those platform supports is limited by the spacing element.

An adjustable platform extension bracket for work platform systems comprises a post member having two posts joined by a plurality of positional structures. A first connection portion forms a first channel such that the first connection portion is symmetrical along an axis parallel with and passing through the channel. The post member is slidingly engaged in the first channel such that at least one of the positional structures is positionable in the channel. The bracket does not require any diagonal support. The dimensions of work platforms, particularly suspended work platform systems, may be extended using the adjustable platform extension bracket.

A modular platform system utilizing a number of components including a platform. The platform is configured so that each of the components may interchangeably connect to any side of the platform. The components include, for example, handrails and stairways, as well as other platforms. The platform and most of the components are formed from single, continuous pieces of metal.
