Abstract:
PCT No. PCT/FI91/00306 Sec. 371 Date Mar. 29, 1993 Sec. 102(e) Date Mar. 29, 1993 PCT Filed Oct. 7, 1991 PCT Pub. No. WO92/06279 PCT Pub. Date Apr. 16, 1992.A method of aligning the feeding beam (6) of a rock drilling equipment by gravity-operated sensors (7x, 7y) indicating the inclination of the feeding beam (6). In the method, the angle values ( alpha , beta ) of the feeding beam (6), indicating by the sensors (7x, 7y) are corrected so that they correspond to the actual angles of inclination of the feeding beam (6). The rock drilling equipment comprises two gravity-operated angle sensors (7x, 7y) measuring inclination in two planes perpendicular to each other. The equipment further comprises a calculator (8) which calculates a difference between the angle value of one angle sensor (7x, 7y) and the actual angle of inclination of the feeding beam (6) in the direction in question on the basis of the angle value obtained by the other angle sensor (7y, 7x) and corrects the value so that it corresponds to the actual inclination of the feeding beam.
