Hydraulic Impact Hammer. A hydraulic hammer incorporates the use of an external energy source to lift the hammer to the top of its stroke. For the single acting hydraulic hammer, the free-falling piston develops the actual energy induced into the pile–much the same power stroke as a drop hammer or a single acting air/steam hammer.
Drop Forging Drop forging is a metal forming process that a billet is inserted into a die and then hammered until it has assumed the shape of the die. The lower die is a stationary part,while the upper part is a moving hammer dropped onto the workpiece in order to deform it. Drop forging can be operated both at high or room temperature.
