Celebrating 10 years of the Chicago Pneumatic Control Power System | Rivet Buster Protection
No other company offers this patented feature to protect your Rivet Busters.
February 17, 2025 - Chicago Pneumatic rivet busters are the only rivet busters with the patented Control Power System (CPS system). The CPS system offers the operator less down time and protection from the operators dryfiring the tool after the rubber bumper is worn past the recommended service limit.
This patented control system automatically prevents the rivet buster from hitting when the rubber bumper is worn to the service limit. (PATENT# US8955616B2)
How it works:
As the rubber bumpers wear, the lower and upper sleeves that hold the tool steel move down and out of the tool retainer. With the patented CP system, as the upper sleeve moves down and out of the cylinder it exposes a bypass when the bumper is worn past the service limit. When this bypass is exposed, it stops the tool from dry firing when the tool steel is not against the work surface. The tool will continue to hit normally, when the tool steel is held firmly against the work surface.
Other Features
Other features on the CP rivet busters are the stepped piston & the bridge in the cylinder and the throttled trigger. The stepped piston and cylinder bridge prevents the operator from accidentally shooting the piston out of the tool, preventing personal injury or property damage. The throttled trigger allows the operator to slowly set the tool steel in place before going to full throttle (much like a viable speed drill).
Conventional pavement breakers feature front head springs that are there to cushion the blows during dry firing.
Rivet busters don’t have this feature, and that is why they are designed with an internal rubber or polyurethane bumper to adsorb the energy created when the tool is being dry fired, it is there to protect the tool when dry firing occurs.
The bumpers do a great job, but they are a designed wearing item, and the more the operator dry fires the tool, the faster they bumpers wear out.
This design works great while the bumper is present, but when the bumper is gone, then the problem for our competitors starts. Without the CPS system, rivet busters have no protection from dry firing the tool.
Competitor's rivet busters will continue to hit even after the bumpers are worn out, and this tears up the tool by breaking the front retainer spring that is holding the tool retainer on the end of the cylinder. Allowing parts to scatter and rendering the tool useless without a new spring and finding all the parts for reassembly.
