A rig adapted for rock bolting comprising a feeding magazine is provided. The feeding magazine comprises a holding structure for bolts and is arranged in conjunction with a rock reinforcement unit. The rig further comprises a feeding device that is arranged to provide the rock reinforcement unit with bolts from the feeding magazine. The rig further comprises a loading magazine comprising a holding structure for bolts, as well as a, relative to the feeding magazine and the loading magazine, moveable picking device arranged to move bolts that are located in the loading magazine such that they are accessible to the feeding device.

Rock bolting rig and method at rock bolting rig

The present invention relates to a method for installation of a rock bolt () in a first drill hole by means of a rock bolting rig (), wherein said rock bolting rig () comprises a carrier (), a boom unit () fastened to said carrier (), and a bolt unit () fastened to said boom unit () via first joint means (), wherein said bolt unit () comprises a feeder unit () including means for displaceable carrying of a drilling machine (), wherein said bolt unit comprises a first (A) end and holding means () for holding said rock bolt (). The method comprises: &#x2014;by means of said first joint means () maneuver said first end (A) of said bolt unit () to a first position for loading of a bolt, &#x2014;when said bolt unit () has been maneuvered to said first position for loading of a bolt, providing a rock bolt () to said bolt unit (), for being held by means of said holding means (), and &#x2014;when said bolt unit () has been loaded with said rock bolt (), maneuver said bolt unit () to a position for installation of said rock bolt () and loaded with said rock bolt () drilling said first hole and installing said rock bolt () in said first hole. The invention also relates to a rock bolting rig.

Method and rock bolting rig for installation of a rock bolt

A rock drilling device comprising a feed beam (), which has a drill end () from which the drill point protrudes at drilling and a rear end() opposite the drill end; a rock drilling machine () movable along the feed beam (); a pressure cylinder (), which is arranged in connection with the feed beam () with one end () movable relative to the feed beam () and one end () fixedly arranged relative to the feed beam (). The pressure cylinder () drives a feed line () for feeding the drilling machine () to and fro along the feed beam (). The feed line () is routed over two outer sheaves () that are arranged at each end () of the feed beam () and a measuring device () for measuring the location of the drilling machine () relative to the feed beam () is arranged to the shaft () of one of the sheaves () and the sheave and the shaft () are arranged such that they rotate together.
