Stairway/Platform System

6 30° 38° 45° 60° 38° 60° 30° 45° Every task and every space is different. That is why the Stairway/Platform System allows users to choose between a comfortable climb and a space-saving design. The sys- tem can be used to build stairways in pitches of 30°, 38°, 45° and 60°. All solutions are individually configured and satisfy the most stringent safety requirements. Guard-rails and platforms can also be added to extend the stairway as appropriate. Ergonomic stairway For all scenarios: Stairways in four different pitches. For more than 100 years, researchers have examined the way that people climb and descend a stairway. When step length, step height and physical exertion are all taken into account, 38° is the ideal pitch in terms of ergonomics. The angle chimes with our natural gait, which is determined by the lifting motion of the leg combined with the forward movement of the upper body. A single flight constructed on this ergo- nomic principle can reach a maximum height of 3.60 metres when employing the recommended maximum number of 18 steps laid down by BGI 561. A perfect diagonal is the most popular pitch for stairways in industrial facilities, but not just because it looks good. Stairways with a 45° pitch have many ben- efits in terms of space requirements, reachable height and ease of use. When working with a recommended maximum number of 18 steps, a single flight can span a height of 4 metres. Space-saving stairway When there is little floor space available or the stairway is not going to be used often – e.g. for maintenance purposes – a space-saving stepladder is an ideal solution. An angle of 60° takes some effort to climb, but gets users to the necessary height quickly. A space-saving stairway to DIN ISO 14122 can reach a maximum height of 4.6 metres in a single flight. Load-carrying stairway If a stairway is in frequent use or is to be used to transport consumables or other loads, users find a flat pitch angle easiest to climb. Users don’t have to lift their legs as high, which relieves some strain, although they have to walk a longer distance than when using stairways with a steeper pitch. A load-carrying stairway can reach a maximum height of 3.2 metres in a single flight. This is due to a combination of the flat pitch and recommended maximum of 18 steps per flight, as stipulated in BGI 561. The standard stairway
