The spring in the brake mechanism of the rotary reducer in concrete pump trucks manufactured by Sany Heavy Industry and Zoomlion Heavy Industry serves a crucial function. Its primary purpose is to provide the necessary force for engaging and disengaging the brakes effectively.

The spring in the brake mechanism acts as a tensioning element. When the brakes are disengaged, the spring is compressed or stretched, storing potential energy. This energy is released when the brakes need to be engaged. The spring's force pushes or pulls the brake components together, creating friction and generating the necessary resistance against the rotation of the boom.

The spring ensures a prompt response and quick engagement of the brakes when required. It helps maintain stability and control over the boom's rotation speed, preventing any sudden or uncontrolled movements. The spring also aids in releasing the brakes smoothly when the operation demands it.
