Apparatus for cleaning pavement expansion joints

摘要

An apparatus for removing sealants from expansion joints in pavement slabs preparatory to replacement of the sealant is adapted for demountable attachment to the rear of a motorized vehicle. The apparatus includes a frame which is pivotably movable about a horizontal axis by means of a linear actuator. A carriage, having a cutting tool bit carried in a tool holder at the trailing edge thereof, is supported on the frame so as to be pivotably movable therewith with such movement employed for positioning and holding the cutting tool in the joint being cleaned. The carriage is free to laterally slide relative to the frame for freely tracking the expansion joint being cleaned.
