Annually, over 500,000 off-highway machines are built with extendable booms, hinged and rotary joints, and powered attachment points, all of which challenge machine designers to increase robustness and reduce warranty claims. Hydraulic and electric power transmission and control signals that cross these pain points require multiple hoses and wires that add cost, increase maintenance, reduce safety, decrease reliability, constrain functionality, and impact machine controllability. A new concept called wireless hydraulics allows for elimination of all the wires between locations on a machine. When wireless hydraulics is combined with a rearrangement of components, all wires and, often most of the hoses, can be eliminated across these machine pain points. In some cases, this can be reduced down to just two hoses, thereby reducing machine costs, increasing space available, and improving machine reliability.
