A temporary platform for assembling elevator equipment in an elevator shaft is arranged substantially in the region of a shaft opening, such that the platform partially sits on a floor surface of the building and partially protrudes into the elevator shaft. The platform includes a bottom frame and bottom plates that lie on or are inserted into the bottom frame. The bottom frame also includes two lateral bottom bars, at least one front and one rear transverse bar that interconnect the two lateral bottom bars, and at least two intermediate bars that are arranged parallel to the two lateral bottom bars. The two intermediate bars are supported substantially by the front and the rear transverse bars.

The disclosure relates to a work over platform apparatus, system, and method of use with trenches and cellars. The apparatus includes two platform portions joined at the center by a set of hinges. The set of hinges is divided to allow for cutouts in each of the platform portions. When deployed the cutout portions are aligned to form an opening that allows work personnel to access the cellar through the work over platform. The work over platform may be collapsed along its hinges for compact transport to and from a work site. The system includes multiple apparatuses positioned adjacent to one another along the same cellar. Outriggers for guidelines are positioned in a novel spider leg fashion to allow greater accessibility to the platform by vehicles. The method includes deploying, using, and collapsing the apparatus.

An apparatus for setting up a ladder or a step on a staircase comprises: a platform on which the ladder or the step can be set up; and a frame to support the platform on the staircase. The frame comprises at least two legs each pivotable about a common pivot axis or about respective pivot axes, wherein the common pivot axis or the respective pivot axes lie in a plane of the platform or parallel to the plane of the platform.

A modular system for forming a floor or platform. The modular system may have vertical dividers for forming divided sections. Multiple horizontal sections are positioned in a side by side arrangement and connected with connectors to form the platform or floor in a desired shape and coverage. Vertical dividers inserted into the horizontal sections and retained in the horizontal sections provide separation of the modular system into compartments.

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.

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.

A multi-level deck system for a blowout preventer and a method, of which the system includes a first deck positioned at least partially around and coupled to the blowout preventer, a second deck positioned at least partially around and coupled to the blowout preventer and vertically spaced apart from the first deck, and a third deck positioned at least partially around the blowout preventer and vertically spaced apart from the second deck.
