The locating block for the rocker arm in the concrete pumps manufactured by Zoomlion Heavy Industry and Sany Heavy Industry serves a key function in ensuring the precise positioning and alignment of the rocker arm.

The primary role of the locating block is to provide a fixed reference point for the rocker arm's position. It is strategically positioned to guide and secure the rocker arm into the correct alignment, ensuring that it operates within the intended parameters.

The locating block helps to maintain the proper positioning of the rocker arm during the pumping process. It prevents the rocker arm from deviating or shifting from its desired position, which could lead to misalignment or improper functioning of the concrete pump.

By securely holding the rocker arm in place, the locating block enhances the stability and reliability of the pumping system. It helps to minimize vibrations or unwanted movements that could affect the accuracy and efficiency of the concrete pumping operation.

Additionally, the locating block aids in optimizing the performance and longevity of the rocker arm and other associated components. By ensuring precise alignment, it reduces wear and tear on the rocker arm, hydraulic cylinders, and other parts, thus extending their operational lifespan.

The locating block also plays a role in facilitating maintenance and servicing of the concrete pump. It provides a reference point for technicians when inspecting or adjusting the rocker arm, allowing for efficient troubleshooting and repair procedures.
