The 13-tooth gear on the output shaft of the rotary reducer in concrete pump trucks manufactured by Sany Heavy Industry and Zoomlion Heavy Industry serves an important function. Its primary purpose is to transmit power and torque from the reducer to the relevant components of the pump truck.

The 13-tooth gear is specifically designed to mesh with other gears or components in the pump truck's system. As the output shaft rotates, the teeth of the gear engage with the corresponding teeth of other gears, allowing for the transfer of rotational force. This gear serves as an intermediary between the rotary reducer and other parts of the pump truck, such as the boom or the concrete pumping mechanism.

By transmitting power and torque, the 13-tooth gear enables the smooth and efficient operation of the pump truck. It ensures that the power generated by the rotary reducer is effectively utilized and distributed to drive the necessary components, allowing for the pumping of concrete with ease and precision.
