The power hammer is a direct descendant of the trip hammer, differing in that the power hammer stores potential energy in an arrangement of mechanical linkages and springs, in compressed air, or steam, and by the fact that it accelerates the ram on the downward stroke. This provides more force than simply allowing the weight to fall.
A trip hammer, also known as a tilt hammer or helve hammer, is a massive powered hammer. Traditional uses of trip hammers include pounding, decorticating and polishing of grain in agriculture .

The equipment used in the drop forming process is commonly known as a power or drop hammer. These may be powered by air, hydraulics, or mechanics. Depending on how the machine is powered, the mass of the ram, and the drop height, the striking force can be anywhere from 11,000 to 425,000 pounds.
A high-speed compressed-air hammer was described in The Mechanics' Magazine in 1865, a variant of the steam hammer for use where steam power was not available or a very dry environment was required. [26] The Bowling Ironworks steam hammers had the steam cylinder bolted to the back of the hammer, thus reducing the height of the machine. [24]
The other new device, hitting at twice or three times the speed of the rivet gun, was the stone carver's hammer – a great blessing for smooth and rapid dressing of granite and marble. In 1930 F.J. Hauschild adapted the original stone carver's hammer into a portable hand-held steel tube frame for the purpose of straightening auto bodies.
