Abstract
A boom for supporting a drilling and bolting tool includes a first portion, a second portion, an actuator for moving the second portion relative to the first portion in a direction parallel to the longitudinal axis. The second portion includes an elongated shaft having a proximal end and a distal end, the proximal end supported by a shaft support for movement relative to the first portion in a direction parallel to the longitudinal axis, the distal end configured to support the drilling and bolting tool.

A boom for supporting a drilling and bolting tool, the boom comprising:
- a first portion including a first end, a second end, and a longitudinal axis extending between the first end and the second end;
- a second portion including an elongated shaft having a proximal end and a distal end, the proximal end supported by a shaft support for translational movement relative to the first portion in a direction parallel to the longitudinal axis, the distal end configured to support the drilling and bolting tool;
- an actuator for moving the second portion relative to the first portion in a direction parallel to the longitudinal axis;
- a guide track;
- and
- a guide member for engaging the track, the guide member positioned on one of the first portion and the second portion, the guide member extending in a radial direction and inhibiting rotation of the shaft support about the longitudinal axis.
A boom for supporting a drilling and bolting tool, the boom comprising:
- a first portion including a first end, a second end, and a longitudinal axis extending between the first end and the second end;
- a second portion including a proximal end and a distal end, the proximal end supported for translational movement relative to the first portion in a direction parallel to the longitudinal axis, the distal end configured to support the drilling and bolting tool;
- a support portion supporting the second portion for movement relative to the first portion;
- a plurality of passages extending at least between the distal end and the proximal end;
- and
- a torsion member extending between the proximal end and the distal end and transmitting torque between the proximal end and the distal end, the torsion member reducing a torque exerted on the passages.
