Abstract

The device is for fitment of rock drills, and comprises a bar (12) and a support component on which is mounted a connection unit (32). The support unit bears the drilling appts., and is rotatably coupled to the bar via the connection unit. A fluid cylinder (50) is connected between the bar and connection unit and produces relative movement between the bar and support unit. A lock pin is inserted between the bar and the connection component to hold the drilling gear in one of several positions. -
