Key features

Double Safety Locking System: Equipped with both a primary hydraulic lock and an automatic mechanical safety pin, completely preventing attachments from falling off even if pressure is lost.

High-Strength Q345B / Hardox Steel Construction: Built with heavy-duty, wear-resistant high-tensile steel to ensure structural integrity and maximum service life under extreme working conditions.

Universal Pin Center Distance: Features a multi-fit design compatible with various top excavator brands (such as Caterpillar, Komatsu, Kubota, Sany, Kobelco, etc.) without modifying original bucket pi

Rapid Attachment Switch in Seconds: Allows operators to change buckets, breakers, and hydraulic shears directly from the cab in under 30 seconds, dramatically reducing downtime and labor costs..

Integrated Hydraulic Check Valve: Features a built-in safety check valve that maintains clamping pressure continuously, ensuring reliable, leak-free operation throughout heavy demolition work.

Compact Lightweight Design Optimized structure minimizes front end overhang weight and loss of breakout force, making it perfect for mini and compact excavators (1 5 tons).

Low-Maintenance & Easy Grease Lubrication: Designed with easily accessible grease nipples and hardened, anti-wear pins for low daily maintenance costs and minimal hassle.

Product Q&A

Q:How can I ensure this quick coupler will fit my specific excavator model?

Simply provide us with your excavator brand, model, and three key dimensions: pin diameter, center distance, and dipper arm width. We will verify or customize the quick coupler to ensure a 100% precise fit.

Q:What is the main difference between a hydraulic quick coupler and a mechanical one?

Hydraulic quick couplers allow the operator to change attachments directly from inside the cabin with a switch, saving labor and time. Mechanical couplers require the operator to manually tighten or release bolts outside the cabin, making them lower cost but less convenient.

Q:How does the safety locking mechanism prevent the bucket or attachment from falling off?

Our hydraulic couplers feature a double safety system, including an integrated check valve that maintains hydraulic pressure and a front/rear mechanical safety lock that automatically keeps the attachment in place even if hydraulic pressure fails.

Q:Will installing a quick coupler significantly reduce my excavator's breakout force?

No. Our quick couplers are designed with a low-profile, optimized geometry that minimizes the distance between the boom and attachment, reducing breakout force loss to a minimum (typically less than 5%).

Q:What material is used for the structural body and locking hooks?

We use high-tensile steel (Q345B) for the body frame and high-wear-resistant alloy steel (Hardox / NM400) for key locking components and pins to guarantee extreme durability under heavy-duty conditions.
