5 Types Popular Excavator Quick Hitch Couplers from China

Excavator quick couplers play a vital role in connecting excavator bucket, ripper, hydraulic rock breaker, hydraulic shear machine and so on. ensuring seamless operation and enhanced efficiency. The right coupling can significantly improve your productivity by reducing downtime during attachment changes and increasing the versatility of your excavator. Choosing the correct coupling also enhances safety on the job site, minimizing risks associated with improper attachment connections. Selecting the best coupling ensures your projects run smoothly and safely.

With the technology revolution of quick couplers for decades, now these 5 types of excavator quick hitches are popular in the market.

Mechanical Quick Couplers

Hydraulic Quick Couplers

Double Lock Hydraulic Quick Couplers

Tilting Quick Couplers

Tilt rotators

1. Mechanical Quick Couplers

Mechanical quick couplers rely on manual force and physical locking mechanisms to secure attachments. These couplers typically involve a pinning system, where pins securely connect the attachment to the coupler. Mechanical quick couplers can either be universal or dedicated, with the former being more adaptable to different attachments.

Some advantages of mechanical quick couplers include:

• Lower initial cost compared to hydraulic couplers
• Less maintenance, as there are fewer moving parts
• Simpler design, making them easily replaceable

2. Hydraulic Quick Couplers

Hydraulic quick hitch is used with construction machines to allow the rapid change of buckets and attachments on the machine. It removes the need to use hammers to manually drive out and insert the mounting pins for attachments. It can be used on the excavator, mini-excavator, backhoe loader and so on.

Advantages of hydraulic quick couplers include:

• Fast and easy attachment changes from within the cab
• Increased safety due to reduced manual handling
• Ability to handle high-pressure applications.

3. Double Lock Hydraulic Quick Couplers

Double-lock quick coupler—an upgrade of the hydraulic quick coupler, which eliminates the manual disassembly of the safety pin and enables truly automatic replacement of attachments in the car. The specially designed connecting rod linkage method uses the same oil cylinder to telescopically control the bayonet at both ends, and controls the two ends separately in two times. The attachment can only be completely separated from the quick change when it is placed on the platform, which avoids the front-end attachment to the greatest extent falling, greatly improving the safety during operation.

4. Tilting Quick Couplers

Quick coupler with tilt motor, Combines all the advantages of a quick coupler and a tilt motor. Flexible with a wide range of attachments and excavator buckets, especially for narrow buckets. The ideal solution, e.g. for sewer construction or directional backfilling.

• Large working range: up to 2 x 90° (180°) tilt angles on both sides
• Including rotary pass-through for hydraulics (Powertilt)
• Tilt motor sealed to protect against damage
• No exposed cylinder, safe design.
• High holding force and robust design for the toughest applications

5. Tilt rotators

A tilt rotator is mounted between the excavator’s arm and bucket. It can be likened to a wrist, allowing the operator to tilt (up to 45 degrees) and rotate the bucket or other attachment infinitely in both directions.

With a tiltrotator for excavator, you can dig at any angle, giving your machine greater maneuverability in tighter spaces. The excavator can dig through obstacles at full power while remaining in place. This gives you many benefits: Less time and more efficiency – digging, contouring and backfilling are easier, with greater precision and more versatility.

A tilt rotator for excavator can also easily clamp objects in narrow corners, and has a wide range of applications.
