Methods for removing concrete accretions from mixing drum

摘要

Methods for removing accretions of cured concrete from within a mixing drum are herein disclosed. One method includes an inserting impact tool mounted upon a boom into the interior of the mixing drum, addressing a bit of the impact tool to an accretion adhered to the inner surface of the mixing drum, and actuating the impact tool to apply a force to the accretions through the bit so as to remove the accretion from the interior surface of the mixing drum.
