Conventional rockbolts, as used for mining and tunneling applications nowadays, have a limited adaptability to rock convergations. In order to overcome this problem, a new sliding-bolt has been developed by Atlas Copco, which is able to keep its loadcarrying capacity under large rock displacements. This rockbolt, consisting of several parts, shall be assembled by a machine in the future. After a preliminary description of the new sliding-bolt, this thesis deals with the pre-investigations, which are necessary for the concept of such an assembly machine. For that purpose, practical experiments are carried out on an existing bolt size to determine the necessary forces for mounting. To verify the results of those experiments, numerical simulation tools are used. In a further step, the produced simulation modell can be applied to rockbolts with other dimensions. This allows for a rough calculation of mounting forces for different bolt sizes. In the second part of this thesis, a machine is designed, which handles the critical mounting step automatically. The design of this mounting device is done with 3D-CAD. The suitability for different bolt sizes is taken into consideration. Finally, the whole concept is complemented with the dimensioning of a hydraulic system, as well as a suggestion for a possible automation of the machine.
