A method for positioning a rock drilling rig according to claim 6, the method comprising: driving the rock drilling rig to a drilling site, where at least one borehole is drilled with a drilling unit included in the rock drilling rig; and moving the rock drilling rig with combustion-engine-free drive equipment, wherein the necessary rotation torque is generated with at least one electric drive motor which is controlled by at least one control device and from which the rotation torque is transmitted over a transmission connection to at least one traction wheel; transmitting the rotation motion of the drive motor over a mechanical anti-slip transmission connection to the traction wheel, and thereby keeping the ratio between the drive motor rotation rate and the traction wheel rotation rate constantly the same during a positioning drive; positioning the rock drilling rig at a drilling site with an uneven or sloped driving surface; using an electric motor to move and stop the rock drilling rig during positioning; providing a speed request for the control device; and keeping the ratio between the drive motor rotation rate and the speed request constantly the same during the positioning drive regardless of the changes in torque load directed to the traction wheel and caused by the changes in the driving surface; measuring rotation of at least one component in the drive equipment with at least one measuring device; determining distance travelled by the rock drilling rig on the basis of the measured rotation information and dimension of the at least one traction wheel; displaying distance information to the operator on the user interface of the rock drilling rig control unit; entering manually into the control unit user interface a distance value that is the new destination location for positioning; and driving the rock drilling rig to the new destination location under the control of the control unit. driving the rock drilling rig to a drilling site, where at least one borehole is drilled with a drilling unit included in the rock drilling rig; and moving the rock drilling rig with combustion-engine-free drive equipment, wherein the necessary rotation torque is generated with at least one electric drive motor which is controlled by at least one control device and from which the rotation torque is transmitted over a transmission connection to at least one traction wheel; transmitting the rotation motion of the drive motor over a mechanical anti-slip transmission connection to the traction wheel, and thereby keeping the ratio between the drive motor rotation rate and the traction wheel rotation rate constantly the same during a positioning drive; positioning the rock drilling rig at a drilling site with an uneven or sloped driving surface; using an electric motor to move and stop the rock drilling rig during positioning; providing a speed request for the control device; and keeping the ratio between the drive motor rotation rate and the speed request constantly the same during the positioning drive regardless of the changes in torque load directed to the traction wheel and caused by the changes in the driving surface; measuring rotation of at least one component in the drive equipment with at least one measuring device; determining distance travelled by the rock drilling rig on the basis of the measured rotation information and dimension of the at least one traction wheel; displaying distance information to the operator on the user interface of the rock drilling rig control unit; entering manually into the control unit user interface a distance value that is the new destination location for positioning; and driving the rock drilling rig to the new destination location under the control of the control unit.
