Mobile triple tool carrier for portable drills

摘要

The mobile triple tool carrier, in contrast to the known developments, permits the mobile use of electrically, pneumatically or hydraulically driven portable drills "on the spot" either as an attachment or as a compact unit with separate drive. The work spindles, which do not need to be either engaged or disengaged or separately operated in some other way, permit a large free working space on account of their special arrangement. Since a large number of operations with rotating tools often consist of three individual but associated work steps (for example: rough drilling - drilling out - counterboring), the embodiment according to the invention of the mobile triple tool carrier offers an effective, economical, simple-to-handle and reliable solution to the tasks in which it is not possible, for example, to machine the workpieces on a machine tool.
