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.

According to an example aspect of the present invention, there is provided a scaffolding arrangement to be attached to a deck structure, comprising a set of aims (2) including a carrier beam (5) for carrying the working levels and support structures needed in work, an attachment frame (1) for attaching the set of arms to the upper surface of the deck structure and platforms (103, 104, 105) for forming working levels.

The invention relates to a scaffolding system with at least one scaffold decking (30). The scaffold deckings (30) preferably have identical fittings (10) which are connected to decking profiles (32) of different heights, in particular in an identical manner. Particularly preferably, the scaffolding system has at least two scaffolding deckings (30), each having identical fittings (10) but decking profiles (32) with different maximum heights (H.sub.32), wherein further preferably the length (L.sub.32) of the decking profile (32) with lower maximum height (H.sub.32) is shorter than for the decking profile with higher maximum height (H.sub.32). In a further preferred embodiment of the invention, the scaffolding system comprises at least three scaffold decks (30), each having identical fittings (10) but decking profiles (32) with different maximum heights (H.sub.32), wherein further preferably the decking profiles (32) are of different lengths and have greater maximum heights (H.sub.32) with increasing length (L.sub.32).

A work scaffold having a platform and leg assemblies rotatably attached to each end of the platform. The platform may have a handle connected to free end that extends out the sides of the platform, which engage with links attached to the leg assemblies and the platform to lock the scaffold in an open or closed position. The platform may have hooks that extend out beyond the ends of the platform from under the platform so a second work scaffold can be situated on the hooks. The platform may be formed of boards with holes that receive cross members. A method for using a work scaffold. A method for forming a work scaffold.

A support member is provided for joining scaffolding plank segments comprising a first support surface for supporting a first scaffolding plank segment and a second support surface parallel to the first support surface for supporting a second scaffolding plank segment. A joining member joins the first and second plank segments, a first retainer is provided for retaining the first scaffolding plank segment on the first support surface and a second retainer for retaining the second scaffolding plank segment on the second support surface. A system is further provided comprising at least two scaffolding plank segments and a bracket, such as that described above, for supporting an end of each of the segments.

Disclosed is a mould system for moulding a blade shell of a wind turbine blade comprising a first mould for manufacturing a first blade shell part of the wind turbine blade; a second mould for manufacturing a second blade shell part of the wind turbine blade; a turning device configured to reposition the first mould between an open mould position and a closed mould position comprising a turning mechanism and a first primary beam connecting the turning mechanism and the first mould; a first scaffold arranged between the first mould and the second mould in the open mould position and comprising a first primary scaffold part and a first secondary scaffold part spaced apart by a first primary scaffold opening, the first primary scaffold allowing the first primary beam to move therethrough during repositioning of the first mould; a first primary movable platform attached to the first mould and being configured to move between an extended platform position and a stored platform position and covering the first primary scaffold opening in the extended position and arranged to expose the first primary scaffold opening in the stored platform position.
