Abstract:
A manually deployed grasping apparatus may be utilized for retrieving objects, such as rocks, concrete chunks and other debris, from vertical excavations such as potholes, boreholes, drilled shafts, etc. Unlike backhoes and other articulated arm machinery, the disclosed grasping apparatus is manually lowered into the excavation by the user. Once the apparatus is adjacent to the object to be retrieved, the opposite facing jaw members of the apparatus are placed into an open position to receive the object. Once the object has been received by the opposite facing jaw members, the jaw members are closed to capture the object. The jaw members are then manually withdrawn from the vertical excavation to retrieve the object.
