## Abstract

A travelling mining appliance, particularly a travelling drilling and/or bolting appliance, having a protective roof. The appliance comprises a driving station used for controlling the movement of the appliance on the ground and a separate operating station, located on the side of the appliance, for controlling the drilling and/or bolting device. According to the invention, the roof is mounted to pivot on the appliance about a vertical axis. It is thus able to move in an angular manner between a first position in which it is located above and protects the driving station, without projecting beyond the width of the appliance and a second position in which projects beyond the side of the appliance and is located above the operating station thus protecting the operator who is standing opposite this station.

## Claims

### Claim 1

In a traveling mining machine with an internal driving station for controlling the movement of the machine, an operating station located on a side of said machine, and a tool controlled by the operating station, the improvement which comprises:
a cab including a substantially horizontal canopy formed with openings enabling an operator to observe an area above said canopy, a substantially vertical shield extending downwardly along one edge of said canopy, and a seat on said vertical shield; and
means defining a vertical pivot axis for said cab at a corner of said canopy remote from said shield whereby said cab is integrally swingable from an internal position wherein said canopy forms the sole roof for said driving station to an external position wherein said shield covers and protects said operating station and extends downwardly behind an operator working said tool from said operating station.

### Claim 2 (depends on 1)

The improvement defined in claim 1 further comprising a ground engageable retractable leg at a lower end of said shield most distal from said vertal axis for immobilizing said cab in its position protecting said operating station.

### Claim 3 (depends on 1)

The improvement defined in claim 1 wherein said cab is constituted by a frame supporting perforated wall sections.

### Claim 4 (depends on 3)

The improvement defined in claim 3 wherein said openings are defined by inclined transverse strips with the inclinations differing from one to another such that the planes of the strips converge towards said seat.
