HYDRAULICALLY OPERABLE APPARATUS FOR MAKING SLIT TRENCHES

摘要

A hydraulically operable implement for producing in the ground vertical deep slit trenches of narrow width which comprises a gripping device adapted to be actuated by an extra long boom and a dipper arm, in which said gripping device suspended on the lower end of beam means through the intervention of a rotatable head connected to the free end of a dipper arm and supporting said beam means is braced relative to said implement by a bridge pivotally connected to a carriage on said implement, the free end of said bridge being provided with a cradle frame extending around said beam means.
