Abstract
The object of the invention is to provide a telescopic feeder which is easier to handle. A first beam is intended to be used in sliding cooperation with a second beam in a telescopic feeder for a rock drilling machine. The first beam comprises at least one guiding stud intended to be guided into a recess in the second beam as the second beam and the first beam are retracted to an end position. The guiding stud is used for locking the first beam in relation to the second beam in a fixed position as the telescopic feeder is fully retracted to an end position.
