Sometimes, different variants of scaffolding use involve slanting surfaces onto which scaffolding frameworks are to be installed. To do so, stability screw jacks with a pivot journal are typically used. Due to the pivot joint, the pivot journal automatically adopts a slope angle of the surface on which the scaffolding is being installed. Please keep in mind that slanting-surface scaffolding is subject to sliding down. To make the use of scaffolding safe, support journals shall be reliably fastened to the surface and braced between each other as close to the zero elevation as possible. Propping and bracing will remove excessive bending moments in the supporting members. Scaffolding can also be installed on symmetric/mirrored slanting surfaces located opposite one another, for example, on inclined boiler bottoms than may have absolutely different shapes (hemisphere, inverted pyramid/cone, etc.). In such cases, forces that cause sliding-down balance each other due to the bracing of the structure between the supporting surface and other points (e.g., boiler walls). Also, in case of symmetric bracing of scaffolding on slanting surfaces, significant compressive forces occur in horizontal members of the ground-level scaffold fitting. In such cases, they should be checked thoroughly for loss of stability.
