Antistatic step platforms

The Branach anti-static step platform ladder was developed for the electric utility market to enable personnel to safely work at heights when maintaining high-voltage substations. Key design guidelines for the ladder were electrical safety, solid construction and convenience of use.

High voltages in substations are capable of inducing a significant static electric charge in the metallic components of step platforms. To avoid exposing personnel to the possibility of electric shock, the aluminium platform standing area is insulated with a non-conductive rubber coating. Plastic coatings were also applied to the other metal components above the platform to minimise the user’s exposure to metal components.

To overcome the common problem of unlevel ground within substations, Levelok ladder levelling systems can be added to the ladder. The system uses quick-connect couplings to attach and remove the levelling units to the ladder’s legs. The legs are then attached as required minimising the weight of the ladder as it is transported.
