MECHANISM FOR TENSIONING FLUID HOSES ON A ROCK DRILL FEED ABSTRACT OF THE DISCLOSURE A tensioning mechanism for the fluid conductor hoses of a feed mounted rock drill comprises a plurality of fluid cyl- inders mounted stationary on a bracket supported midway along the length of the drill feed channel. Elongated tubular pistons are slidably supported in the cylinders and are connected to the respective hoses. The cylinders may be charged with pressure fluid such as grease or the like to bias the pistons to tension the hoses and prevent damage to the hoses or interference with movement of the drill.
