Advanced Hydraulic Quick Coupler System

The excavator is equipped with an advanced hydraulic quick coupler system designed to simplify and secure operations. By pressing the red safety switch, the operator activates the safety mechanism before engaging the rocker switch. Only after pressing this switch can the rocker be moved, ensuring that accidental activation is completely avoided. This added layer of protection prevents misoperation and improves overall safety during work.

With this system, changing attachments becomes faster and more reliable. The hydraulic quick coupler not only saves time but also allows operators to adapt to different job requirements without unnecessary delays. This design greatly enhances both productivity and convenience in excavation projects.

Optimized Hydraulic Hose and Valve Connections

The hydraulic system has been carefully engineered to maintain durability and efficiency. The hose assembly is designed to stabilize the hydraulic lines and firmly connect the quick coupler valve block with the hydraulic quick coupler. If the hydraulic hose at the bucket end is damaged or ruptures, it can be directly replaced without affecting the rest of the system. This modular design reduces downtime and makes on-site repairs more efficient.

By providing a robust connection between the hydraulic components, the system ensures smoother operation and longer service life. The optimized hose routing also reduces wear and tear, protecting the excavator’s hydraulic system under demanding conditions.

Support for Multiple Attachments and Applications

To increase versatility, the excavator is designed to support a wide range of auxiliary attachments. The hydraulic quick coupler system allows operators to switch tools with ease, opening up more possibilities for different working conditions. From buckets to specialized tools, the system enhances flexibility and efficiency on construction sites.

In addition, a dedicated return line is pre-installed for a mower attachment. This thoughtful design ensures that the excavator can seamlessly support mowing applications, expanding its utility beyond excavation to land clearing and maintenance. With this feature, the machine becomes a multi-functional solution for operators working in diverse industries.

Safety Features with Anti-Burst Valve

Operator safety is a priority in this excavator’s design. The boom cylinder is equipped with an anti-burst valve to prevent dangerous accidents in the event of hydraulic hose failure. If the boom cylinder’s inlet hose ruptures, the one-way valve automatically blocks the hydraulic oil flow. This prevents the boom from dropping suddenly due to gravity, protecting both the operator and the machine from damage.

This safety mechanism ensures that the excavator remains stable even under unexpected conditions. By preventing uncontrolled movement, the anti-burst valve not only enhances operational safety but also prolongs the machine’s lifespan by reducing the risk of structural damage.
