  • Patent number: 11391019
    Abstract: A system for routing fluid in a fluid system of a machine includes one or more hoses and one or more clamping arrangements. The hoses are adapted to extend from a main control valve, pass through a frame portion of the machine, and reach up to an end of a fluid cylinder to route fluid between the main control valve and the fluid cylinder and actuate the fluid cylinder. An actuation of the fluid cylinder powers a movement of an implement of the machine. The clamping arrangements are adapted to secure corresponding portions of the one or more hoses to corresponding locations on the frame portion of the machine. One clamping arrangement is interchangeable with another clamping arrangement to secure a corresponding portion of any hose of the one or more hoses to a corresponding location on the frame portion of the machine.
