Standard solutions
The standard solution is cable steps per 600 mm and ladder steps per 300 mm. The ladder steps are solid round bars, and the width of the steps is 400 mm. The cable steps are small U-profiles, and the width of the steps is not less than 250 mm on both sides of the climbing ladder, providing a total width for cables of 500 mm. Cables and feeders can be fixed to the cable steps on both sides providing a capacity for many cables and feeders. The ladder is placed inside the cross section and is leaning forward in the conical part of the towers, and vertical in the top part providing comfortable climbing conditions.
A safety rail can be fixed to the steps of the climbing ladder. Safety rail is normally included in Ramboll delivery.
Costumer specified climbing ladder and cable ladder solutions are possible; such as ladder with back guards or other types of cable steps.
To reduce the costs of the manufacturing of the towers, special details have been developed to ease the production (e.g. easy diagonal gusset plate connection).
