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.

The invention relates to a scaffolding arrangement with a scaffolding assembled from individual scaffolding components for internal construction or maintenance work within a coker drum standing upright on the ground and which has a lower end portion with a cross-section which tapers in the direction of the longitudinal axis of the drum towards a closable opening at the lower end of the coker drum, the scaffolding comprising: a support section with several support posts each having a lower and an upper end, the support posts, with their lower ends being supported outside of the coker drum on the ground and each of them, through the opening provided on the lower end of the coker, extending in a vertical direction into the coker drum, wherein the support section comprises several support posts spaced from one another, a support frame comprising a plurality of support beams which are detachably connected to one another, the support frame being attached to and supported by said support section, a first working platform which is arranged on top of the support frame, the first working platform being preferably located within the tapered lower end portion of the coker drum; and a scaffold tower section having one or more further working platforms which is/are each arranged in an axial direction above the first working platform inside the coker drum. The vertical loads of the scaffolding as a whole, are solely transferred to the ground via the said support section of the scaffolding, which is fully self-supported. The invention further relates to a scaffolding for an aforesaid scaffolding arrangement (FIG. 1)

A bridge or other construction comprising a deck, in which the deck is designed to be lightweight and durable, such as by including aluminum, and readily installable on a main bearing structure of the bridge or other construction (e.g., without welding and/or without drilling or otherwise creating holes into the main bearing structure of the bridge or other construction), even if the main bearing structure of the bridge or other construction is based on different material (e.g., steel).

A set of accessories for use in combination with a scaffold is comprised of at least one pair of support hooks, at least one stirrup member for facilitating stepping up or down from the scaffold, at least one material holder.

A modular space frame support system comprises an upper frame comprising a plurality of joists interconnected with a plurality of interconnection structures; a lower frame comprising a plurality of joists or chords interconnected with a plurality of interconnection structures; at least two interconnection structure brackets, wherein a first of the at least two interconnection structure brackets is connected to one of the plurality of interconnection structures of the upper frame and a second of the at least two interconnection structure brackets is connected to one of the plurality of interconnection structures of the lower frame, each interconnection structure bracket comprising a hollow tubular section, and at least one chord-engaging structure; and at least one chord secured at a first end to the first of the at least two interconnection structure brackets and at a second end to the second of the at least two interconnection structure brackets.

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.
