One of the most remarkable features of the PMP 6.5R120 gearbox is its exceptional torque transmission capacity. Concrete mixer trucks require a substantial amount of torque to rotate the heavy mixer drum, especially when it is filled with a large volume of concrete. The PMP 6.5R120 is engineered to handle these high - torque demands with ease. It can efficiently transfer power from the engine of the truck to the mixer drum, ensuring a consistent and stable rotation speed. This stable rotation is vital for maintaining the quality of the concrete mix. Any fluctuations in the drum speed can lead to uneven mixing, which can have a negative impact on the strength and workability of the concrete.

Variable Speed Ratios

The gearbox offers a wide range of speed ratios. This flexibility is a boon for concrete mixer truck operators. During the loading and unloading of concrete, a lower speed ratio can be selected. This allows for precise control of the mixer drum's rotation, ensuring that the concrete is discharged or loaded evenly. On the other hand, when the truck is in transit, a higher speed ratio can be engaged. This increases the efficiency of the operation by allowing the drum to rotate at a faster speed, which helps in maintaining the homogeneity of the concrete mix while covering longer distances in a shorter time. The smooth shifting between different speed ratios is facilitated by an advanced synchronizer system. This system minimizes gear clash and ensures seamless transitions, contributing to the overall smooth operation of the gearbox.
