Abstract

A method and a device for controlling the feeding on a feed beam (3) of a to and fro movable rock drilling machine (2), which includes a percussive device and a rotation motor providing a rotation moment, wherein a parameter related to the rotation moment is monitored and the feeding is controlled by flow control as a response to variation of the value of the parameter, wherein a feed flow to a fluid motor means providing the feed is reduced as a function of a change of the parameter value corresponding to an increase of the rotation moment over a first level. For parameter values corresponding to the rotation moment being below the first level, feeding is controlled by pressure control as a response to the variation of the value of the parameter, wherein a feed pressure for said fluid motor means is reduced as a function of a change of the parameter value corresponding to an increase of the rotation moment. The invention also concerns a rock drilling machine and a drilling rig.
