As a key component connecting the excavator and attachments, the quick coupler directly affects construction safety, operating efficiency and the service life of equipment. Therefore, when selecting an excavator quick coupler, apart from price, greater importance should be attached to its safety-oriented structure, machining precision, durability, and actual working performance.
Jiangtu Triple Locking Quick Coupler is designed and manufactured in strict accordance with high-level standards. Featuring safety protection upgrades, optimized structures, precision machining, and durability tests, multiple technical improvements comprehensively boost product performance, delivering a safer, more efficient, and more reliable quick-coupling solution for construction work.
Internationally certified triple locking structure, comprehensively safeguarding construction safety
Jiangtu Triple Locking Quick Coupler features a design that meets EU standards. Through a triple locking mechanism, it effectively reduces the risk of the attachment detaching.
Even in special cases—such as cylinder internal leakage or piston rod breakage—the quick coupler maintains a secure grip on the pins, preventing accidental attachment detachment and ensuring greater safety for operators and the job site.
Compact in size and height, reducing energy consumption while improving handling performance
Compared to similar products on the market, the Jiangtu flat-push sliding structure quick coupler features a lightweight design with a more compact body and a lower profile.
Its low center of gravity structure effectively reduces the load on the excavator’s working equipment, minimizes digging force loss, and lowers fuel consumption. It also reduces the risk of collisions and interference in confined workspaces, allowing for more flexible equipment operation.
Dual-layer slide rail design enhances load-bearing capacity and service life
As a critical component for supporting attachments, the moving hook of the quick coupler adopts a dual-layer slide structure for more even overall force distribution, effectively preventing localized stress concentration. It is well-suited for mounting large and heavy-duty attachments.
Meanwhile, high-precision machining technology enhances the fitting accuracy of components, delivering smoother operation of the quick coupler with reduced vibration and impact, and significantly extending the service life of the moving hook.
Rigorous precision machining ensures long-term, stable operation
During the manufacturing process, Jiangtu Quick Coupler employs precision CNC boring and milling for critical components, such as the housing and jaw, and strictly controls assembly clearances.
The precise fit between pins and bores effectively minimizes shake and abnormal noise, reduces wear on pins and bushings, and ensures superior structural precision and stability.
Boost bucket operating efficiency for smoother construction operations
When working with buckets, Jiangtu quick coupler keeps the bucket body stable and reduces shake, enabling tighter fitting of the bucket mouth.
During construction, it effectively cuts soil spillage and material loss, lowers repeated digging cycles, delivers more continuous digging and loading operations, and greatly improves construction efficiency.
Six stringent standards for building a trustworthy high-quality quick coupler
Built on six stringent quality standards, Jiangtu quick couplers go through six special finishing processes and six full-procedure inspections. Every unit must pass six major tests: cold resistance, heat resistance, corrosion resistance, impact resistance, fatigue resistance, and operational agility.
From raw-material selection and precision machining to pre-delivery testing, Jiangtu consistently adheres to a high-standard manufacturing philosophy, ensuring each quick coupler maintains stable performance under long-term, high-intensity construction conditions.
