  • Patent number: 5636648
    Abstract: A mobile rotator jet sewer cleaner vehicle for cleaning a sewer line by fluid pressure, the vehicle having a fluid supply for delivering the fluid under pressure to a hose wound on a reel assembly which can be selectively wound or unwound in a vertical direction, wherein a bearing assembly movable in a horizontal direction is secured on a platform and a reel assembly is mounted on and movable with the bearing assembly. A control for selectively actuating winding and unwinding the hose on the reel assembly is provided, and this control, which may also include other instruments and controls for operating the sewer cleaner, is movable with the bearing and reel assembly. In another embodiment of the invention, the platform telescopes into and away from a recess in the vehicle chassis, so that the reel and bearing assemblies are extended from the vehicle when in use, but may be retracted into the recess when desired, and in such event the retracted jet sewer cleaner may be enclosed within the vehicle.
