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 modular scaffold, which includes parts to be joined to each other, which parts are at least standards, ledgers, working platforms and the necessary railings, and also ladders. The parts of the modular scaffold are fabricated mainly from plastic and/or fiber composite.

A scaffold that is quick and easy to assemble while still implementing safety measures. The scaffold can include end caps that resist or prevent users from falling off the ends of the scaffold. The end caps are quickly assembled to the scaffold with a removable rod and pin mechanism. Moreover, to prevent a user from falling off the front or back of the scaffold, a pole and a mid-rail connector can be connected to the scaffold across the front or back, respectively, between an upper barrier and a lower platform. The pole can be inserted through connectors that are coupled to the scaffold, and can also be connected to mid-rail brackets for additional structural stability.

An apparatus for supporting workers and materials above-grade on both the cave and gable ends of a structure is disclosed. The apparatus can be combined with one or more additional staging apparatuses to create a staging system for the support of persons or materials while work is being done on a structure, e.g., roofing, siding, etc. The modular design of the apparatus simplifies installation, such that it can be readily attached to a roof or other support member of a structure by a single person, and facilitates the adjustable vertical positioning of people or materials along the walls of the structure. The staging system can also include a rail member for safety support and alternative scaffolding arrangements.

A scaffold safety assembly for facilitating a worker to service a scaffold includes a scaffold that has a frame comprising a leg portion. A step unit is removably attachable to the leg portion of the frame of the scaffold to facilitate a worker to stand on the step unit. The step unit extends laterally away from the leg portion when the step unit is removably attached to the leg portion. In this way the gate facilitates the worker to access various areas of the scaffold without standing on the scaffold. A gate is removably attachable to the leg portion of the frame of the scaffold. Additionally, the gate is positionable adjacent to the platform to inhibit the worker from falling off of the platform.
