The folding platform is also available as a contractor version (“loonwerker”). In this version the platform has been adapted so that it can be used in as many situations as possible.
The maximum length over which the platform can drag the power cable and water hose is approximately 100 meters. You can extend the maximum distance with a reel set. This is useful for longer facades, in addition, a reel set also offers a solution for uneven or rough terrain.
