Abstract
Abstract The novel apparatus comprises a first, power unit module of limited mobility and a second, bolter unit which is flexibly and disengageably coupled to the first unit by means of an umbilical line. In one embodiment of the invention, the power module comprises the controls whereat and from when the satellite bolter is (remotely) operated, and in an alternate embodiment, the satellite bolter itself includes controls and a control station for an operator to be accommodated thereat, to control the bolter directly.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
105 words
Roof bolting apparatus, comprising: a first unit which defines a power module; a second unit which defines at least one satellite bolter; first coupling means which flexibly and disengageably couple said bolter remotely to said module; and second coupling means which disengageably attach said bolter directly or immediately to said power module; wherein said module comprises a source of pressured hydraulic fluid; said bolter comprises hydraulic-fluid-operative tramming means, position-stabilizing jacks, and roof bolting means; and at least one of said coupling means comprises means for supplying pressured hydraulic fluid operative thereof to said tramming means, said stabilizing jacks, and said bolting means from said source.
Claim 2
Dependent Claim
