CONNECTING WORKING VEHICLE GROUP USED FOR REPAIRING TUNNEL LINING

PROBLEM TO BE SOLVED: To provide a connecting working vehicle group suitable for performing repair work of tunnel lining for a railroad efficiently in a short time. SOLUTION: The connecting working vehicle group 1 includes a working vehicle 30 and a working vehicle 40 connected to each other and travelable on railroad rails 2. The working vehicle 30 is equipped with a boom type high lift working machine 32 slidable at fixed strokes S2 in a longitudinal direction. The working vehicle 40 is equipped with a lock-bolt boring machine 42 movable at fixed strokes S1 in the longitudinal direction. The strokes S2 of the boom-type high lift working machine 32 are determined so that a worker who rides on a working bucket 32c of the boom-type high lift working machine 32 can perform work to each part within a work range to the inner peripheral surface 4a of tunnel lining concrete 4 by the lock bolt boring machine 42.
