摘要: A vehicle includes at least one hose extending from the vehicle and configured to extend below ground through a manhole, and a light system. The light system includes a storage member, such as a retractable reel, coupled to the vehicle, a flexible line wrapped at least partially around the storage member, and a light source coupled to the flexible line. The storage member is adapted to selectively extend and retract the light source together with the hose below ground, and the light source is storable on the vehicle adjacent the storage member. The light source has a self-contained power source. In some systems, the flexible line and/or the light source are removable from the vehicle so they can be moved to a remote location from the vehicle.

摘要: A service mode selection system for a service vehicle is provided for simplifying a control for setting the vehicle in a desired service mode. The system includes a control system for receiving an operator's selection of service mode via a service mode selection device and controlling vehicle components to automatically set the vehicle in a selected service mode. The service mode selection device can be arranged in a cab of the vehicle and allows the operator to conveniently select a desired service mode, thereby achieving a work-ready machine with as few operator inputs as possible.

摘要: A self-rotating tube cleaning nozzle assembly is disclosed that includes at least one debris exclusion feature. The nozzle assembly includes a main body defining an internal fluid passageway, a nozzle mounted to the main body, and a sleeve rotatably disposed about the main body. In one aspect, the sleeve having at least one discharge port in fluid communication with the main body internal fluid passageway for discharging a spray and rotating the sleeve about the main body. The debris exclusion feature is defined between the main body and the sleeve and includes a stepped portion on an exterior surface of the main body that faces and overlaps with a complementarily shaped stepped portion on an interior surface of the sleeve. The debris exclusion feature forms a tortuous pathway that eliminates or reduces contaminant ingress.
