    Air hydraulic drilling unit BE 33

    The basic design of the BE 33 consists of a vane motor powered by com­pressed air, a pneumatic cylinder, and a closed hydraulic system. The total stroke length can be variably subdivided into rapid advance and working feed over the whole range. The throttle/check valve in the hydraulic sys­tem permits exact setting of the feed rate and high speed return.
