Extension to increase effective radius of spraying or application device has fluid and/or gaseous media transporting lines for each arm and connected to arms in region of rotatable bearings

摘要

The extension (1) to increase the effective radius of a spraying or application device has fluid and/or gaseous media transporting lines (6,7) for each arm (2,3). The transporting lines are connected to the arms in the region of rotatable bearings (9,10) which interconnect the arms and connect the extension to a fixed base structure (37) respectively. Feed is through a central shaft (11), and drain is through this shaft in an axial direction and a rotatable connection on one side, and on the other side through an annular gap encompassing the shaft and enclosed by an outer cylinder, and through a bush leading from the cylinder.
