Tippmann Industrial Products, Inc. has introduced the Propane Hamer, what it states is the first propane-powered post hammer. It is useful for driving a range of posts, rebar, etc., up to 3.5 inches in diameter. Propane is cost effective and time efficient and allows the user to operate the unit and drive several hundred posts on a single 14 oz. propane tank. When the tank runs out, you simply throw away the tank and put in a new one. The Propane Hammer weighs under 45 pounds, and is completely self contained allowing users the freedom to work in remote areas. There is no need for air compressors or hydraulic units or any other type of external power source, allowing this unit to be easily operated by one person.
