1. A valve testing assembly comprising:
- an articulated arm assembly configured to mount on a support in a manner permitting pivoting of the articulated arm assembly about a substantially vertical axis with respect to the support, the articulated arm assembly having a first arm and a second arm, the second arm of the articulated arm assembly is pivotally connected to the first arm at a first end of the second arm and the second arm is movable away from toward the first arm such that when the first arm of the articulated arm assembly is connected to the support, the the second arm of the articulated arm assembly is movable away from and toward the support;
a frame mounted on a second end of the second arm of the articulated arm assembly such that the frame is movable toward and away from the support when the arm assembly is mounted on the support;
a valve testing assembly coupled to the frame, the valve testing assembly comprising a valve tester havinga motor,a connector structure mounted on the motor for rotation by the motor, the connector being configured to connect to a valve to move the valve between open and closed conditions, anda motor control which controls the motor,wherein the frame and the motor are pivotable about a first substantially horizontal axis with respect to the articulated arm assembly when the arm assembly is mounted on the support.

Abstract
A valve tester suspension assembly for allowing one person to perform the tasks necessary to test underground valves includes an articulated arm attached to a mobile base such as a vehicle. The articulated arm may be biased such that the biasing assists in supporting the weight of a rotating assembly positioned at a distal end of the articulated arm. The articulated arm is pivoted to permit positioning of the rotating device in a substantially horizontal orientation at a desired position within a three dimensional space adjacent to the base to which the articulated arm is attached. A method of use is also described.

8. A valve testing system comprising:
-
a mobile base with wheels; an articulated arm assembly mounted on the mobile base in a manner permitting pivoting of the articulated arm assembly about a substantially vertical axis with respect to the mobile base, the articulated arm assembly having a first arm and a second arm, the second arm of the articulated arm assembly is pivotally connected to the first arm at a first end and the second arm is movable away from and toward the first arm such that when the first arm of the articulated arm assembly is connected to the mobile base, the second arm of the articulated arm assembly is movable away from and toward the mobile base; a frame mounted on a second end of the second arm of the articulated arm assembly toward the second arm of the articulated arm assembly for permitting movement of the frame toward and away from the mobile base; a valve testing assembly coupled to the frame, the valve testing assembly comprising a valve tester having a motor, a connector structure mounted on the motor for rotation by the motor, the connector being configured to connect to a valve to move the valve between open and closed conditions, and a motor control which controls the motor, and wherein the valve testing assembly and the frame are pivotable about a substantially horizontal axis with respect to the articulated arm assembly when the arm assembly is mounted on the mobile base. - View Dependent Claims (9, 10, 11, 12, 13, 14)
