ABSTRACT:
A tray-like receptacle or container for catching falling debris from bridge deck demolitions is disclosed. The receptacle extends under a bridge deck and a support arm affixed to an end of the receptacle is disposed above the bridge deck. A crane suspends the receptacle with a cable attached to the support arm and another cable affixed to the receptacle is drawn in to tilt the receptacle so that crushed, collected concrete slides off an open end of the receptacle and into a dump truck. The support arm of the receptacle is disconnectable for storage and transportation purposes.
