ABSTRACT:
A beam picker adapted to be mounted on the boom tip of a conventional hydraulic crane is described to facilitate the removal of shoring beams positioned beneath a completed structure. The beam picker comprises a first support which is mounted on the outer end of a hydraulic crane and which has a second support pivotally secured thereto about a horizontal axis. A third support is rotatably and pivotally mounted on the second support so that the third support may be rotated and tilted relative to the second support. Movable jaws are provided on the third support for grasping the lower flange of the shoring beam.
