- Cradle unit 32 generally includes a supporting guide 104 formed at the extremity of support arm 86 which guides and supports a tong unit carrier frame 106 in pivoting and radially movable relation through a roller unit 108 as shown.
- Supporting guide 104 is formed of generally rectangular configuration with a pair of upwardly extending ears which form a clevis 110 for attachment by means of a pin to support fork 90.
- Parallel trackways 112 are horizontally and radially defined within guide 104 and closed at the distal end of support arm 86 by a closure bar 114 connected across the trackways to guide 104 by fasteners such as cap screws 116 as shown.
- a flanged guide block 118 is snugly fitted in sliding relation within trackways 1 12 with the flanges of the guide block abutting the sides of the trackways and maintaining the guide block in radial alignment with support arm 86.

- Guide bar 134 is adapted to be rigidly connected by means of fasteners such as cap screws 136 to pipe rotating unit 30 as shown.
- cradle unit 32 provides parallel alignment and limited vertical movement between rotating unit 30 and back-up unit 28 while permitting adjustable limited radial movement and vertical pivoting of the entire power tong assembly 26.
- the vertical movement between back-up unit 28 and rotating unit 30 is needed to permit longitudinal displacement between a section of pipe being held stationary by back-up unit 28 and a section of pipe being held and rotated by rotating unit 30 as the two sections are being threaded into or out of connection.
- Means shown in the referenced disclosures may be advantageously utilized to compensate for the weight of rotating unit 30 during its vertical movement with respect to back-up unit 28.
- Pivotal movement or rocking of power tong assembly 26 about the axis of roller unit 108 is resiliently limited by a stabilizing unit 140 and 140, as shown in FIGS. 1, 2 and 11. Only unit 140 needs to be described in detail since unit 140' is constructed in mirror image thereof.
- Unit 140 is shown as a flanged bracket 142 extending inwardly and downwardly from support arm 86 of yoke 24.
- a bolt 144' extends upwardly through a lug 146 projecting from back-up tong 28 and through a flange 148 projecting from bracket 142 and is secured in position by adjustable lock nuts 150.
- a pair of resilient coil springs 152 are disposed between the flange 148 and lock nuts 150.
- the bolt is fitted through lug 146 and flange 148 sufficiently loose to permit the radial movement of tong assembly 26 as previously described.
- Such construction provides firm yet resilient vertical support of tong assembly 26 against movement about the axis of roller unit 108. Such resilience permits compensation for minor deviations from a vertical position of well pipe extending through tong assembly 26.
- the power tong and positioning apparatus may have substantial and considerable mass which will require considerable force to pivot the power tong assembly into position over the well bore and away from the well bore as required during performance of well drilling or service operations.
- the lower support member 14 may be equipped with a gear and pinion arrangement connected to mounting base 40 and driven by a hydraulic motor or the like to pivot the entire structure supported by column 10 as may be desired.
- the positioning apparatus is provided with the power tong assembly 26 as shown in FIGS. 1 and 2, positioned over a well bore and secured in position by retaining pin 50.
- the fluid fitting 102 of cylinder 96 is connected to a hydraulic power system (not shown) which is suitable to inject hydraulic fluid into the cylinder 96 and release the fluid from the cylinder at controlled rates and in controlled volumes to raise and lower tong assembly 26 as desired.
- the pipe When the pipe is to be disconnected, the pipe is raised or lowered through tong assembly 26 and tion of the pipe joint is within potential grasp of backup unit 28 and free of possible grasp by rotating unit 30.
- Back-up unit 28 is next actuated to firmly grip the lower section of the pipe joint against rotation and the rotating unit is actuated to grip the upper section of the pipe joint to be rotated.
- the rotating unit 30 is further actuated to rotate the pipe to unscrew and disconnect the threads of the joint. The operation may then be repeated for the next lower pipe joint to be disconnected in the pipe string.
- the lower pipe joint When the pipe is to be connected the lower pipe joint is positioned and firmly grasped by the back-up unit. Another section of pipe is lowered and centered or stabbed through rotating unit 30 to be threaded into the lower pipe section. The pipe is then rotated by the rotating unit to thread the joint into final connection. Such procedure is repeated for the next section of pipe to be connected.
