Abstract
An air-operated hammer, comprising a hollow ram; a frame; an air cylinder and piston assembly disposed within the ram, wherein a top of the cylinder and piston assembly is attached to a top of the frame and wherein a piston rod of the cylinder and piston assembly is attached to a bottom of the ram; an air flow control valve mounted on and in fluid communication with a manifold disposed on a top of the frame; a first pressurized air reservoir comprising a first flexible hose of a first size attached to an outside surface of the frame, wherein lifting of the ram is caused by pressurized air from the pressurized air reservoir being supplied to and entering a bottom of the cylinder, wherein pressurized air entering a bottom portion of the cylinder causes the piston to raise the ram.
