Quick Coupler

This hydraulic quick coupler for breakers uses high-strength structural components, precisely machined pins, and hydraulic locking assemblies in its design, focusing on improving connection stability, locking reliability, and ease of daily maintenance. The coupler can be matched or customized according to the excavator's tonnage, breaker mounting size, pin diameter, center distance, and hydraulic line requirements.

How can I confirm whether the coupler fits my excavator and hydraulic breaker?

Please provide the excavator brand and model, operating weight class, dipper-arm mounting dimensions, breaker model, pin diameter, pin-to-pin distance, ear plate width and hydraulic interface information. The manufacturer can then check the mechanical and hydraulic requirements and recommend a suitable or customized configuration.

Is the locking system of the hydraulic quick coupler safe?

The coupler normally uses hydraulic locking together with a mechanical lock or safety confirmation feature to improve attachment retention. Before every operation, confirm that the locking mechanism is fully engaged and the pins are correctly positioned according to the product manual. Do not perform impact work before the locked status has been confirmed.

Can the coupler be used only with a hydraulic breaker?

The compatible attachment range depends on the coupler dimensions, locking design and rated operating conditions. Some models may also fit hydraulic shears, grapples, compactors or buckets. However, the attachment interface, weight, load direction and hydraulic requirements must be checked; compatibility should not be judged by appearance alone.

What routine maintenance does the hydraulic quick coupler require?

Regularly inspect the pins, bushings, locking components, cylinder, hose fittings, welded areas and fasteners. Lubricate as specified in the manual, keep the hydraulic oil and fittings clean, and address looseness, leakage, abnormal wear or deformation promptly. Maintenance intervals should be adjusted to operating frequency and site conditions.

What should I do if the coupler leaks oil or does not lock completely?

Stop operation immediately, park the excavator in a safe position and release system pressure. Check the hose fittings, seals, locking pins, cylinder and possible debris. Do not remove hydraulic components under pressure or force the coupler into service by hammering or temporary tying. Contact the manufacturer or a qualified technician if the issue cannot be resolved.
