Claim:
The valve tester suspension assembly comprising: an articulated arm assembly for coupling to a mobile base, the articulated arm assembly comprising: a first arm portion configured to couple to the mobile base; a second arm portion rotatably mounted on the first arm portion to permit rotational movement of the second arm portion with respect to the first arm portion about a substantially vertical axis; a third arm portion pivotally mounted to the second arm portion to permit pivot movement of the third arm portion with respect to the second arm portion; a frame mounted on the third arm portion for movement with respect to the third arm portion; a rotating assembly coupled to the frame; and a shaft having a first end removably mounted on the rotating assembly to rotate the shaft and a second end for removably mounting on a valve to be tested; wherein the frame is pivotable about a first axis with respect to the third arm portion, the frame is pivotable about a second axis with respect to the third arm portion, the first and second axes being oriented substantially perpendicular to each other; at least one control for the rotating assembly being mounted on the frame adjacent to the rotating assembly, wherein the at least one control comprises a torque adjustment control adjusting an amount of torque applied by the rotating assembly to the shaft to prevent overstressing of the valve assembly being exercised.
