The stability of the drive sprocket on the rear side is better than that on the front side, and It can prevent the final drive from being impacted by external force; the wheelbase of the crawler on the ground is always greater than the wheelbase, so the stability of the forward work is good, and the sideways operation should be avoided as much as possible; the excavation point should be kept close to the machine to improve the stability and excavator .
If the digging point is far away from the mini excavator, the operation will be unstable due to the forward movement of the center of gravity; the lateral digging is less stable than the forward digging, if the digging point is far away from the center of the mini excavator, the machine will be more unstable, so the digging point and the center of the body should be kept appropriate distance to make the operation balanced and efficient.
