Boom Stability Control: A Dynamic Machine Control Solution

The power of Eaton’s CMA valve and Pro-FX® Control application development tools combine to solve a complex machine problem quickly.


Concrete boom pump trucks are used to transport concrete to construct high-rise buildings and other difficult-to-access sites. Typical truck boom lengths can range from under 20 to over 60 meters (65 to 200 feet). As boom length increases, machine operational challenges also increase. In operation, as the boom is maneuvering and pumping concrete, it tends to oscillate because of the mechanical flexibility of the boom and the compliance of the hydraulic oil in the cylinders. To address the oscillation, additional workers are typically required to hold the boom tip hose and concrete pumping speed is also decreased. This, in turn, reduces machine productivity and increases the potential risk for the operators securing the boom.
