Abstract

A drill boom is longitudinally extensible and contractible by a power cylinder. The drill boom extension mechanism includes a boom extension member longitudinally slidably guided in a journal casing affixed to the outer end of the drill boom. The journal casing has longitudinal grooves cooperating with elongated wedge or guide means on the boom extension member for guiding the latter non-rotatably in the drill boom, the wedge or guide means having a length exceeding the length of the journal casing and traversing axially through the journal casing.
