Hydraulic Quick Coupler for 20 Ton Excavator Heavy Duty Quick Hitch Attachment with Hydraulic Hose Kit

The Hydraulic Quick Coupler for 20 Ton Excavator is a heavy-duty excavator attachment connecting device designed for compatible excavators in the approximately 20-ton operating weight class.

Also known as an Excavator Quick Hitch, Hydraulic Quick Connector, Hydraulic Quick Coupler, or Excavator Attachment Coupler, this product is designed to help operators change compatible excavator attachments through a hydraulic locking and release mechanism.

The hydraulic quick coupler allows suitable attachments to be connected to the excavator arm without requiring conventional manual removal and installation of attachment pins during every changeover.

It is commonly used for switching between compatible excavator buckets and other construction attachments, helping reduce attachment changeover time and improve equipment operating flexibility.

The pictured quick coupler features a heavy-duty yellow steel structure, reinforced side plates, large pivot pin connections, hydraulic locking components, and specially shaped attachment engagement hooks.

The product can be supplied with corresponding hydraulic hoses, fittings, electrical control components, and installation accessories, depending on the selected package configuration.

JISION supplies hydraulic quick couplers, excavator attachment parts, hydraulic hose assemblies, and construction machinery accessories to equipment owners, machinery contractors, repair workshops, and international spare parts distributors.

Installation and Safety Recommendations

Correct quick coupler installation and safe operation are essential for preventing accidental attachment release.

Before installation:

1. Confirm the excavator model, operating weight, and machine serial number.

2. Verify the excavator arm and linkage pin dimensions.

3. Measure the attachment pin center distance and bracket width.

4. Confirm the quick coupler's rated capacity and compatible attachment weight.

5. Inspect the hydraulic hoses, fittings, and locking mechanism.

6. Install the quick coupler according to the manufacturer's instructions.

7. Confirm that the primary locking mechanism and required secondary safety retention function correctly.

8. Perform the specified attachment engagement and verification procedure before lifting or operating the attachment.

9. Inspect the coupler, locking components, hydraulic lines, and attachment connection regularly.

Safety Notice: Never operate an excavator attachment unless the quick coupler is fully engaged and secured according to the manufacturer's instructions.

Installation and operation should be performed by trained personnel. Follow all applicable equipment safety requirements and operating procedures.
