Abstract: A hydraulic system is disclosed. The hydraulic system includes a first actuator fluidly coupled to a first rotating group in a first closed-loop circuit, a flow control module fluidly coupled to the first closed-loop circuit via a first conduit, a second actuator fluidly coupled to the flow control module via a second conduit, a second rotating group in selective fluid communication with the first conduit and the second conduit via the flow control module, and a controller operatively coupled to the flow control module. The controller is configured to operate the flow control module in a first mode and a second mode. The first mode effects fluid communication between the second rotating group and the first closed-loop circuit via the first conduit, and blocks fluid communication between the second rotating group and the second actuator via the second conduit.

Abstract: A method for mobile three-dimensional (3-D) printing of a component of a machine is disclosed. The method includes determining a distance between a transport and a customer based on, at least, positioning information provided by a positioning system. The method further includes determining a route for the transport to travel to the customer based on, at least, the distance between the transport and the customer. The method further includes printing, at least in part, the component of the machine using a 3-D printer while the transport travels along the route, the 3-D printer being associated with the transport and travelling with the transport along the route.
