Abstract (en)
[origin: WO2010092237A1] The invention relates to a method for using a retainer, and to a retainer. The retainer(14) comprises a first clamping arm (18a) and a second clamping arm (18b) provided with clamping jaws (21a, 21b) for clamping a drill rod (9), a rock bolt or the like. The clamping arms are turned in relation to their pivot points (19a, 19b) by an actuator (20), whereby the clamping jaws move either towards or away from each other. On the portion between the pivot points of the clamping arms there are shape members that interconnect the movements of the clamping arms to make them interdependent and thus synchronize the movements of the clamping arms in both directions of movement of the clamping arms.
