Advantages

It adopts advanced control methods such as full power control, electric over-control, load sensing control, electro-hydraulic proportional control, and equipped with imported hydraulic parts to achieve high efficiency, high precision and high reliability.

With imported two-speed gearbox, the main winch can precisely control the rapid up and down movement of the groove cutter and low speed feed. The electro-hydraulic proportional tracking control system ensures the synchronization of the slurry hose roller, the hydraulic hose roller and the main winch.
