The invention is directed to a method for the construction of an industrial plant, in particular a petroleum refinery, by means of scaffolding units, each of which will be assembled from individual scaffolding components, comprising the following steps: Providing a 3D-construction plan in which building structures of the industrial plant are recorded; Drawing of scaffolding units to be used for the construction of the industrial plant in the 3D construction plan of the industrial plant including modifying of the 3D construction plan with respect to at least one building structure of the industrial plant for use of a predetermined scaffolding unit; Building of the industrial plant according to the modified construction plan and by use of the scaffolding units drawn in the 3D construction plan. The method according to the invention, allows for a significant reduction of scaffolding costs incurred during the construction of any industrial plant. The cost saving effects of the method according to the invention can be further increased by modifying the construction plan, wherever possible, for the use of the predetermined scaffolding units which may be of different or equal design.

To ensure maintenance operations for an architectural structure using a mast climber without any limitation on the stability of a mast and locations where a mast can be erected. A side wall 101 of an architectural structure 100 is fitted with a fixing member 130 at a level higher than the ground 500. The fixing member 130 is fitted with fixture studs 132. A mast 200 is erected on the fixing member 130 with its lower end secured to the fixture studs 132. A climbing work platform 210 that travels up and down the mast 200 is fixed to the mast 200. A worker performs maintenance operations on the climbing work platform 210.

Disclosed is a device for enabling an aircraft maintenance operator to access the exterior body of the aircraft. The device is adapted to be releasingly anchored to the fuselage of the aircraft. The device comprises a platform disposed above and transversely with respect to the fuselage and a pair of legs straddling the fuselage wherein, the platform extends between the pair of legs. Each leg comprises a leading means for leading the operator to reach the platform from the ground therethrough.

A moveable wing gantry for servicing a wing of an aircraft is configured to be positioned around a wing of an aircraft to provide access to overwing and underwing surfaces of the wing of the aircraft. The wing gantry includes a service deck positioned underneath the wing of the aircraft. An operator platform is moveably attached to the service deck and operable to move along the length of the service deck. A chair support is moveably attached to the operator platform and operable to move across the operator platform in a direction substantially perpendicular to the length of the service deck. The wing gantry includes a pivotable span platform positioned above the wing of the aircraft and pivotable between a raised position and a lowered position. The wing gantry is customizable to different aircraft wing types and styles.
