100 Lb. Bradley Horizontal Helve Mechanical Hammer.

Of the many configurations of mechanical hammers, the vertical guided-ram is the most prevalent. They are simple, and easy to use and maintain. To my knowledge no manufacturer offers new mechanical hammers. The Little Giant Company, however, carries an inventory of replacement parts. It also operates a repair service, and offers reconditioned hammers for sale when they are available. Air hammers are divided into two main categories – “Utility” and “SelfContained.” Utility hammers require an external high-pressure, high-volume air supply. Sizes range from 100 lb. up to “Don’t use near a seismograph.” They have a more compact footprint than a selfcontained hammer and are, in our experience, a little more finicky when it comes to delicate work. Self-contained hammers make their own air (low-pressure/high-volume) and are more controllable.
