A device for mounting pre-fabricated elements of tunnel equipment includes two manipulators installed on a trolley by means of rotary shafts, each of those includes two links arranged as a crank and a con-rod, connected to each other with possibility of motion, this provides possibility of turn and fixation in given position by means of a drive, and on the free end of each con-rod a holder for elements of pre-fabricated equipment is clevis-mounted. The rotary shafts of the manipulators are placed symmetrically with respect to the vertical axis of the trolley, and manipulators made identically one to another are mounted on the trolley in such a way that they can be laid one to inside of the other one when both are in the upper position with respect to the rotary shafts. |
