Claims

[Scope of utility model registration request]

In the air stamp hammer described above, a ram is attached to the lower end of a piston rod suspended from a main cylinder for raising and lowering the ram, and the main cylinder is controlled by a control valve for changing the direction of operation and its operating mechanism. It consists of a brake mechanism that operates to brake the piston rod below the main cylinder, and a control means that operates this brake mechanism, and this control means operates the brake mechanism when the ram rises to a predetermined upper limit. A ram braking device for an air stamp hammer, the ram braking device being operably associated with the ram and the control valve operating mechanism.
