A pivoting support assembly with a selective position locking capability may comprise a base, a first support arm movable with respect to the base, a first pivot joint pivotally mounting the first support arm to the base, and a first position locking assembly configured to lock a selected position of the first support arm with respect to the base. The first position locking assembly may comprise a first hydraulic motor mounted on the first pivot joint and having a fluid input and a fluid output with a fluid path defined therebetween such that fluid movement on the fluid path between the fluid input and the fluid output operates the first hydraulic motor. The first position locking assembly may comprise a first lock valve in communication with the first hydraulic motor and configured to selectively block fluid movement through the fluid path of the motor.

1. A pivoting support assembly with a selective position locking capability, the assembly comprising; a base;a first support arm movable with respect to the base;a first pivot joint pivotally mounting the first support arm to the base to move about a first pivot axis;a first position locking assembly configured to lock a selected position of the first support arm with respect to the base, the first position locking assembly comprising: a first extensible actuator located at the first pivot joint and having a first fluid port and a second fluid port, the first extensible actuator being mounted on the base and the first support arm in a manner such that locking the first extensible actuator against extension and retraction resists movement of the first support arm with respect to the base, a fluid path being defined between the first and second fluid ports; anda first lock valve in fluid communication with the first extensible actuator and configured to selectively block fluid movement through the fluid path between the first and second ports. 2. The assembly of claim 1 wherein the first lock valve is in communication with at least one of the first fluid port and the second fluid port of the first extensible actuator to block fluid movement through the at least one of the fluid ports. 3. The assembly of claim 1 wherein the first support arm is pivotable with respect to the base about a first pivot axis. 4. The assembly of claim 1 wherein the first position locking assembly is located at the first pivot joint. 5. The assembly of claim 1 wherein the first extensible actuator comprises a housing defining a fluid chamber in communication with the first fluid port and the second fluid port, a piston located in the fluid chamber, and a rod connected to and movable with the piston. 6. The assembly of claim 5 wherein the housing of the first extensible actuator is being fixed to one of the base and the first support arm and the rod of the first extensible actuator is fixed to another one of the base and the first support arm. 7. The assembly of claim 1 wherein the first pivot joint includes a first spindle, a first collar receiving the first spindle, and a first offset member fixed to rotate with the first spindle and with respect to the first collar, an arm mount being located on the first support arm and an offset mount being located on the first offset member at a location spaced from the first pivot axis, the first extensible actuator including a housing and a rod, the housing being mounted on one of the arm mount and the offset mount and the rod being mounted on an other one of the arm mount and the offset mount. 8. The assembly of claim 1 wherein the first lock valve is characterized by having a movement condition permitting substantially free flow of fluid through at least one of the fluid ports on the first extensible actuator and a lock condition resisting free flow of fluid through at least one of the fluid ports on the first extensible actuator. 9. The assembly of claim 8 wherein the movement condition corresponds to a substantially open condition of the first lock valve and the lock condition corresponds to a substantially closed condition of the first lock valve. 10. The assembly of claim 8 wherein the first position locking assembly includes a first control configured to actuate the first lock valve between the movement condition and the lock condition. 11. The assembly of claim 1 additionally comprising a tool mounted on the first support arm such that a position of the tool is movable by movement of the first support arm with respect to the base. 12. The assembly of claim 11 wherein the tool comprises a valve operating device. 13. The assembly of claim 1 additionally comprising a second support arm mounted on and movable with respect to the first support arm, a second pivot joint pivotally mounting the second support arm to the first support arm to move about a second pivot axis, and a second position locking assembly configured to lock a selected position of the second support arm with respect to the first support arm. 14. The assembly of claim 13 wherein the second position locking assembly is located at the second pivot joint. 15. A pivoting support assembly with a selective position locking capability, the assembly comprising; a base;a first support arm pivotable movable with respect to the base;a first pivot joint pivotally mounting the first support arm to the base such that the first support arm and base pivot with respect to each other about a first pivot axis;a first position locking assembly configured to lock a selected position of the first support arm with respect to the base, the first position locking assembly comprising: a first plurality of discs located at the first pivot joint and secured to the first support arm to rotate with the first support arm about the first pivot axis, a second plurality of discs located at the first pivot joint and secured to the base to rotate with the base about the first pivot axis, the first plurality of discs and the second plurality of discs being stacked in a substantially alternating manner;a pressure assembly configured to press the discs of the first and second pluralities of discs together to resist rotation of the first and second pluralities of disks with respect to each other to resist rotation of the first support arm with respect to the base; anda pressure release assembly configured to at least partially release pressure from the first and second pluralities of discs to permit rotation of the first plurality of discs with respect to the second plurality of discs to permit rotation of the first support arm with respect to the base. 16. The assembly of claim 15 wherein the first pivot joint includes a first spindle and a first collar receiving the first spindle, the first plurality of discs being secured to the first collar and the second plurality of discs being secured to the first spindle. 17. The assembly of claim 15 wherein the pressure assembly includes a pressure plate exerting axial pressure against the discs of the first and second pluralities of discs, and at least one spring acting on the pressure plate in an axial direction.
