ABSTRACT:
Cleaning apparatus usable to clean those portions of a tunnel wall or the like which are located behind railing means typically placed along a walkway beside the wall, such as in a freeway tunnel. A guidance carriage engages the railing and is movable therealong. A support carriage, which can be moved along the walkway, carries a plurality of motor driven circular brushes for cleaning these wall portions. Between the guidance carriage and the support carriage are located linear fluid motors urging the carriages in laterally opposite directions, the support carriage in turn urging the brushes into contact with the wall, and the guidance carriage being urged by said motors against the railing which provides horizontal support for the guidance carriage. The railing also provides vertical support for the guidance carriage while the walkway provides vertical support for the support carriage. The guidance carriage and the support carriage may be removably engageable with each other to enable the cleaning apparatus to be easily positioned on and removed from the walkway.
