摘要： A boom for supporting a drilling and bolting tool includes a first portion including a first end and a second end, 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; an actuator for moving the second portion relative to the first portion parallel to the longitudinal axis; and a fluid passage for conveying pressurized fluid between the first end of the first portion and the drilling and bolting tool adjacent the distal end of the second portion, the fluid passage positioned within the first portion and the second portion.

摘要： A boom (30) for supporting a drilling and bolting tool (34) includes a first portion (42B), a second portion (46B), an actuator for moving the second portion (46B) relative to the first portion (42B) in a direction parallel to the longitudinal axis. The second portion (46B) includes an elongated shaft having a proximal end (70) and a distal end (74), the proximal end (70) supported by a shaft support for movement relative to the first portion in a direction parallel to the longitudinal axis, the distal end (74) configured to support the drilling and bolting tool (34).
