1. An assembly for cleaning elongated tubes comprising:
a rail;
a rotation mechanism;
at least one lance extending outwardly from the rotation mechanism and over the rail;
a translation mechanism coupled with the rotation mechanism and being operable to move the rotation mechanism and the at least one lance in unison in one of a first direction and a second direction relative to the rail;
a plurality of trolleys operatively engaged with the rail and supporting a portion of the at least one lance; said plurality of trolleys being movable along the rail in the one of the first direction and the second direction in response to operation of the translation mechanism;
a stacker operatively engaged with one of the translation mechanism and the rotation mechanism; and
a channel defined in each of the plurality of trolleys; wherein the stacker is selectively receivable through the channel of one or more of the plurality of trolleys when the translation mechanism moves the rotation mechanism in the first direction.
