摘要： The present invention is a self-contained hydraulic hammer which is mounted on a hydraulically mobile frame. The hydraulic hammer is capable of travelling in either forward or reverse directions and is provided with liftable weights to which a tool for digging or breaking up a surface is attached. The hydraulic hammer is equipped with time delay controls which: 1) momentarily stop the travel of the hydraulic hammer as the weights and the attached digging tool free fall from a raised position until the digging tool impacts the surface to be busted up, and 2) cause the hydraulic hammer to resume travel as the weights are again raised in preparation for another impact. The hydraulic hammer rapidly repeats these cycles of impact and travel to break up a surface. Adjustments are provided on the hydraulic hammer for regulating the force of the impact and the distance travelled between impacts in order to match the hydraulic hammer's impact and travel cycles to the break characteristics of the surface to be removed.

摘要： A device removably attaches to a skid steer and is used for breaking up asphalt, concrete, etc. A hollow rod is suspended from the device, and a nipple provides liquid communication to the interior rod chamber of the hollow rod. A head is provided on a lower end of the rod and a cylinder is movably provided around the rod's lower end so that upper and lower cylinder chambers are formed within the cylinder, above and below the head. Perforations provided in the lower end of the rod provide liquid communication between the rod chamber and the upper cylinder chamber. The lower cylinder chamber is charged with gas. A weight and a breaking tool attach to the bottom end of the cylinder and move upward and downward in conjunction therewith. A switch provided on the frame is tripped as the weight is raised, thus sending an electrical impulse to a timer, causing it to momentarily supply electricity to dump and directional valves, simultaneously closing them. The timer then resets and removes electricity from the valves, allowing them to simultaneously reopen. When the dump and directional valves are open, hydraulic fluid is pumped into the upper cylinder chamber and the weight is lifted. When both valves close, the dump valve quickly drains the upper cylinder chamber, thus causing the weight and the breaking tool to fall to the ground.
