Abstract
An attachment that is configured for attachment to an arm of a piece of heavy construction equipment. The attachment is configured to rotate a section of pipe during break-out (i.e. disconnection or disassembly) from another section of pipe and/or make-up (i.e. connection or assembly) with another section of pipe. The attachment is configured to break the joint or torque the joint, unthread or thread pipe, and lift the pipe under the power of the heavy construction equipment.
Claims14
A pipe handling attachment configured for attachment to a prime mover, comprising:
- a head assembly that is configured to be attached to an arm of the prime mover;
- a main beam assembly pivotally mounted to the head assembly so that the main beam assembly is pivotable about a first pivot axis;
- at least one tilt actuator connected to the head assembly and to the main beam assembly to pivot the main beam assembly about the first pivot axis,
- a vise assembly mounted on the main beam assembly, the vise assembly includes a stationary vise and a make/break vise that is rotatable relative to the stationary vise;
- at least one pipe roller gripping assembly pivotally mounted on the main beam assembly, the at least one pipe roller gripping assembly is configured to grip a pipe and rotate a pipe gripped thereby about a longitudinal axis of the pipe;
- the at least one pipe roller gripping assembly is pivotally movable relative to the vise assembly and the main beam assembly between a lowered position and a raised position;
- at the lowered position the at least one pipe roller gripping assembly is disposed adjacent to a side of the vise assembly, and at the raised position the at least one pipe roller gripping assembly is further away from the vise assembly compared to when the at least one pipe roller gripping assembly is at the lowered position.

A pipe handling attachment configured for attachment to a prime mover, comprising:
- an upper head assembly that is configured to be attached to an arm of the prime mover;
- a lower head assembly rotationally attached to the upper head assembly to permit the lower head assembly to rotate relative to the upper head assembly about a rotation axis;
- a main beam assembly pivotally mounted to the lower head assembly so that the main beam assembly is pivotable about a first pivot axis;
- at least one tilt actuator connected to the lower head assembly and to the main beam assembly to pivot the main beam assembly about the first pivot axis;
- a vise assembly mounted on the main beam assembly, the vise assembly includes a stationary vise and a make/break vise that is rotatable relative to the stationary vise;
- at least one gull-beam assembly that is pivotally mounted to the main beam assembly for pivoting movement downward and upward relative to the main beam assembly between a lowered position and a raised position about a second pivot axis which is parallel to the first pivot axis;
- a pivot actuator connected to the main beam assembly and connected to the at least one gull-beam assembly for pivoting the at least one gull-beam assembly about the second pivot axis;
- and
- a pipe roller gripping assembly mounted on the at least one gull-beam assembly, wherein at the lowered position of the at least one gull-beam assembly the pipe roller gripping assembly is positioned closer to the vise assembly compared to at the raised position of the at least one gull-beam assembly.

A pipe handling attachment configured for attachment to a prime mover, comprising:
- a head assembly that is configured to be attached to an arm of the prime mover;
- a support assembly pivotally mounted to the head assembly so that the support assembly is pivotable about a first pivot axis;
- at least one tilt actuator connected to the head assembly and to the support assembly to pivot the support assembly about the first pivot axis,
- a vise assembly mounted on the support assembly, the vise assembly includes a clamping vise and a make/break vise that is rotatable relative to the clamping vise;
- a pipe roller gripping assembly mounted on the support assembly, the pipe roller gripping assembly is configured to grip a pipe and rotate a pipe gripped by the pipe roller gripping assembly about a longitudinal axis of the pipe;
- and
- the pipe roller gripping assembly is movable relative to the vise assembly and the support assembly between a lowered position and a raised position, at the lowered position the pipe roller gripping assembly is disposed adjacent to a side of the vise assembly, and at the raised position the at least one pipe roller gripping assembly is spaced axially outward from an end of the support assembly.
