  • Patent number: 4715761
    Abstract: A pipe handling machine having vertical tracks mounted on a rotatable base. A carriage is mounted on the vertical tracks for vertical movement. A multisection telescoping boom is mounted on the carriage, and a pipe-engaging head is mounted on the end of the boom. The base may be carried on a movable trolley, which engages a set of tracks. The tracks run across the rig floor, from well center to a setback area. A second set of tracks may run across the rig floor, transverse to the first set.

  • Patent number: 4613849
    Abstract: An interference warning device for an oil well drilling rig having a derrick, traveling equipment, a racker arm, and a block retractor. Fluid activated sensors provide electric signals when the traveling equipment is within a selected vertical distance from the racker arm, when the racker arm is within a selected horizontal distance from the vertical axis of the derrick, or when the block retractor has extended the traveling equipment to within a selected distance from the fully extended position. The operator is informed when any one of the sensors is activated, cautioned when any two of the sensors are activated, and warned when all three sensors are activated. The drawworks may be braked when all three sensors are activated.

  • Patent number: 4603464
    Abstract: A well tool and method for making up and breaking out connections between sections of drill pipe. The tool will jump the upper pipe section out of the connection when the connection has been completely unthreaded, and will guide the upper pipe section during stabbing. A piston and cylinder assembly is mounted on the carriage for raising and lowering the pipe spinner relative to the carriage. The tool also has an actuator and a pilot valve for automatically opening the clamping cylinders of the spinner whenever the upper pipe section is raised by the pipe elevator.

  • Patent number: 4589503
    Abstract: A top drive well drilling apparatus, having a drive unit for rotating a drill string. The drive unit is connected to a carriage, which guides the drive unit along a vertical guide track. A wrench assembly, for making and breaking connections between the stem of the drive unit and the drill string, can be moved between a working position along the stem and a retracted position away from the stem. The wrench assembly can also be moved vertically, and is mounted on the carriage.

  • Patent number: 4345864
    Abstract: Apparatus for moving stands of pipe in a derrick having a powered turret mounted in a selected position relative to the derrick and a vertical leg supported and rotated by the turret. A powered dolly is mounted on the vertical leg and moves one end of a power arm to selected positions along the vertical leg. A pipe gripping head is mounted to the opposite end of the power arm. A scissor arm is rotatably connected at one end in mid-region of the power arm and at the other end to the vertical leg. As a consequence, the pipe gripping head moves reciprocally in a straight line to engage, move, and disengage stands of pipe.
