R7 is one of the lightest rotator in its class, weighing more than 25% less than those of other brands. The weight of the rotating link has a significant impact on the performance and efficiency of small excavators. Most R7 users can use it efficiently without adding counterweights.

In addition, the height between the upper pin and bucket pin is also the lowest in its class. This minimizes the decrease in bucket digging power even when the rotating link is attached, increasing efficiency.
