Abstract:
1. A firefighting monitor for redirecting a flow of fluid from a pressurized fluid source through a conduit, said conduit comprising: four consecutive segments rotatably connected in series wherein an axis of rotation is provided at each connection between said four segments; a first segment connected to said fluid source followed in series by a second segment connected to an outlet of said first segment, a third segment connected to an outlet of said second segment and a fourth segment connected to an outlet of said third segment forming consecutively at each connection a first axis of rotation, a second axis of rotation and a third axis of rotation respectively; said monitor includes a redirection of an azimuth angle of said conduit by an azimuth rotation between said first segment and said second segment on said first axis of rotation; and said monitor further includes a redirection of an elevation angle of said conduit by a second rotation between said second segment and said third segment on said second axis of rotation in a second rotation direction and by a third rotation between said third segment and said fourth segment on said third axis of rotation in an opposite direction to said second rotation direction; and said fourth segment comprises a discharge end having a discharge centerline which intersects with a centerline of said second axis of rotation and a centerline of said third axis of rotation, thereby minimizing rotational torque on said connection between said second segment and said third segment and the rotational torque on said connection between said third segment and said fourth segment.
