The present invention is a folding jackhammer trolley. The trolley is comprised of a main frame, wheel frame, and handle frame. One or more adjustable brackets are provided on the main frame to retain a jackhammer. The brackets are adjustable by hand and require no tools to properly secure a jackhammer. Rollers are provided on the front end of the main frame, and wheels are provided on the wheel frame to allow the trolley to be mobile. Clutch locking mechanisms are actuated by levers provided on the handle bars. When the levers are engaged by a user the angles of the handle frame and wheel frame are adjustable relative to the main frame. The adjustments allow for prying motions to be carried out and for the handle frame to suit different user heights.
