Excavator Proportional System

Excavator proportional system refers to the hydraulic system that controls the movement of the excavator's arm, bucket, and other attachments. This system is designed to provide precise and proportional control over the excavator's movements, allowing the operator to perform delicate and precise operations with ease.

The excavator proportional system uses a series of hydraulic valves and sensors to control the flow of hydraulic fluid to the various components of the excavator. These valves are controlled by the operator's movements of the joystick, which sends signals to the hydraulic system to adjust the flow of fluid to the various components.

The proportional system allows the operator to control the speed and force of the excavator's movements with great precision. This is particularly important for tasks that require delicate and precise movements, such as digging around sensitive underground utilities or performing demolition work in tight spaces.

Overall, the excavator proportional system is an essential component of modern excavators, providing operators with the control and precision they need to perform a wide range of tasks safely and efficiently.
