In terms of propulsion, how is the HYEX track mounted?

The correct answer is that the HYEX track is hydraulically activated. This means that the propulsion system of the excavator utilizes hydraulic fluid to power the movement of the tracks. Hydraulic systems are favored in heavy machinery like excavators because they allow for precise control, efficient power transmission, and the ability to handle heavy loads with relative ease. The hydraulic activation provides advantages in maneuverability and loading capabilities, making it suitable for various excavation tasks.

Traditional manual controls and mechanical systems might not offer the same level of efficiency or responsiveness as hydraulic systems in track-mounted equipment, and electrical operation is generally associated with different types of machines, typically not in this heavy machinery context. Hence, hydraulic activation is the most effective and commonly used method for propelling excavators like the HYEX.
