ABSTRACT:
A fluid control system for a mobile aerial tower which includes a plurality of positioning elements such as first and second interconnected booms and a turntable for rotating the booms about a vertical axis. The control system comprises first and second variable speed pumps and a bank of three double acting valves operatively connected between the pumps and the positioning elements so as to control the direction of fluid flow thereto, and a pneumatically linked remote control system for selectively controlling the speeds at which the pumps operate and for selectively operating the valves to direct fluid between either of the pumps and any one of the positioning elements, or alternatively between both of the pumps respectively and any two of the positioning elements, or alternatively between the pumps collectively and any one of the positioning elements.
