Abstract:
1. A mobile machine with a swivel and, above the swivel, an operator's seat and an engine that drives a hydraulic pump, where the engine and seat can fully swivel any number of rotations without limitation and the operator can control a hydraulically driven tool below the swivel, comprising: (a) a set of wheels or tracks on which the machine rides supporting a support structure; (b) coupled to and supported by the support structure, a vertical swivel such that components coupled to an upper side of the swivel can swivel about a vertical axis relative to the support structure any number of rotations without limitation; (c) coupled to and supported by the upper side of the swivel, an engine that drives a hydraulic pump and an electrical generator, an operator's seat and operator's controls; (d) coupled to and supported by the support structure and fixed to a lower side of the swivel, a hydraulically controllable tool; (e) a wireless communication link that carries control communications from the operator's controls to at least one wirelessly actuatable electronically actuated hydraulic valve below the swivel which hydraulic valve effects control of the tool; and (f) a power source coupled to the electronically actuated hydraulic valve which power source provides electrical power to operate the hydraulic valve and to operate a wireless communication component coupled to the hydraulic valve.
