Concrete Pump Manufactures Association

To formalize the guideline for the design, manufacture, testing, safe use, inspection and maintenance of concrete pumps for the North American market.

The CPMA has always been an advocate for the concrete pumping industry since it was incorporated in 1999. Its initial focus was on the creation of both a safety standard specifically written for concrete pumping, and a standardization of safety-related features on the equipment built and sold.

After four years of development, the CPMA Safety Standard was officially completed and released in 1999. Its three chapters covered the best practices for safety as it relates to: 1) equipment construction and installation, 2) inspection, testing and maintenance, and 3) applications and operations. In later years, this standard was the basis for what is today’s American National Standard (ASME B30.27) and Canadian Standard (CSA Z151) for safety, and has been reviewed for inclusion in a possible worldwide standard (ISO TC195).

The CPMA has also been responsible for the creation and/or adoption of several safety features that can be found on today’s equipment:

  • In the late 1990’s, the hopper grate safety switch feature was adopted which cut power to the pumping and hopper agitator systems if the hinged grate on the hopper was opened.
  • Along with the CPMA safety standard, a set of standardized cautionary and warning decals were created and adopted. These decals have been improved and increased over the years with the intent of supplementing the manufacturing member’s own on-board instructions and operations manuals. These decals have also been translated into Spanish for greater adaptability to the American workforce.
  • The standardization of the pattern used by the remote control joysticks to control the articulating boom arm movements (three patterns existed at that time, causing confusion when operators changed machines they were working with).
  • The operator supervision warning system was adopted to give an operator a warning signal/alarm when the boom was not in the transport mode and they either A) attempted to place the machine in drive-away mode or B) attempted to operate the outrigger support system.

CPMA Standards

In 2009, the B30 committee of ASME adopted nearly all of the contents of the former CPMA 27-2000 Safety Standard into it's ASME B30.27 - 2009 edition. Upon it's publication, the ASME B30.27 became the American National Standard (ANSI), and the CPMA 27-2000 was discontinued and deleted.

The CPMA wholly endorses the entire ASME B30.27 Safety Standard, including the following minimum boom and support structure inspection schedule:

  • First 5 years -- every 2,000 working hours, or at least once per year, whichever occurs first.
  • 5 to 10 years -- every 1,000 working hours, or at least once per year, whichever occurs first.
  • 10 years and older -- every 500 working hours, or at least once per year, whichever occurs first.


The members of the CPMA are dedicated to supplying equipment and accessories to the concrete pumping industry that meet or exceed the requirements contained in the ASME B30.27 Safety Standard.

One requirement of being a CPMA member company is the commitment to having the products being manufactured subject to the successful completion of an independent audit at least once every three years. This audit reviews all pertinent sections of the current ASME B30.27 standard and determines if randomly-selected representative samples from the manufacturer meet or exceed the necessary criteria. If there are discrepancies, the CPMA member must correct these items within a specified time frame and on all related equipment being produced and sold in North America.

In short: CPMA Membership = Certification Compliance

Once the member has shown that a family of equipment models/accessories has successfully passed an audit, they are allowed to display both the CPMA member decal and the CPMA Certification decal (above). This is your sign that the equipment being purchased has been produced with these safety regulations in mind and is intended for continuous safe operation when used as directed.
