ABSTRACT:
A mobile system for delivering a fluid to a fluid application area includes a vehicle, an arm carried by the vehicle and movable between a retracted position and an extended position, a fluid delivery system carried by the vehicle and including at least one fluid delivery device coupled too the arm, a mechanism for maneuvering the arm between the retracted position and the extended position, a sensor mounted on the vehicle for sensing the approach of an obstacle in the path of the arm, and a control circuit responsive to the sensor for causing the arm maneuvering mechanism to retract the arm towards the retracted position when the sensor detects an approaching potentially interfering obstacle and for extending the arm towards the extended position when the relative positions of the arm and the obstacle are no longer potentially interfering. A safety breakaway mechanism is incorporated into the system for enabling the arm to deflect when struck by an undetected obstacle. The control circuit optionally provides either a fixed cycle time or a variable cycle time. When operating over a variable cycle time, the control circuit includes a circuit for measuring the speed of the vehicle and a circuit for computing the length of the variable cycle time in accordance with the measured vehicle speed. The control circuit may be overridden by a vehicle occupant to directly operate the arm maneuvering mechanism.
