Types of Excavator Attachments: Excavator Quick Couplers
Excavator quick couplers are an essential component of heavy machinery in construction, as they enhance productivity and adaptability. With the help of these couplers, operators can quickly and easily transition between different duties on an excavator by connecting various attachments to the machine. Quick couplers are therefore a crucial part of many construction projects since they decrease downtime and boost production.
Excavator quick couplers come in a variety of varieties, each with special characteristics and advantages. S Type Couplers, Dual LockTM Pin Grabber Couplers, and CW Series Couplers are a few of the well-liked choices. Furthermore, businesses like as Steelwrist provide sturdy and small quick couplers, suitable for excavators of various weight classes, with or without integrated oil couplings.
Rotating and tilting couplers are two other types of excavator quick couplers that offer more control and flexibility while in use. For example, spinning couplers may rotate 360 degrees, while tilting couplers can be inclined up to ±45° or ±90° in hydraulic or mechanical variants. Because of their adaptability, operators can easily navigate confined locations and complete challenging jobs.
Excavator Quick Coupler Types
Excavator quick couplers are made to make attachment changes easier, boost productivity, and cut down on downtime. Quick couplers come in two main varieties: mechanical and hydraulic. Every one of these has benefits and particular uses in the industry.
Manual Quick Couplers
A common choice for budget-conscious operators, Manual Quick Couplers come in a variety of styles but generally involve manually entering or removing a pin to lock the bucket in.
This is commonly referred to as a manual “pin-puller” coupler – where the front of the coupler is an open slot that you can hook on a bucket, and the rear is a dedicated pin hole that you fix you attachment to. This retains the breakout force while still improving your efficiency.
These are generally significantly cheaper than Mechanical or fully Hydraulic Quick Couplers while still offering an increase in efficiency, but you’re still working with adding and removing pins to swap attachments out.
You’d be surprised at how much of a difference it makes compared to direct mounting every single attachment though – it really is a big quality of life increase.

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
Hydraulic Quick Couplers
Hydraulic quick couplers, as the name suggests, use hydraulic power to secure attachments to the excavator. Hydraulic couplers can also be universal or dedicated, offering the same versatility in attachment compatibility. These couplers are designed to provide a more convenient and efficient method of changing attachments compared to their mechanical counterparts.
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, as seen in this GlobalSpec report
Whether excavator operators choose mechanical or hydraulic quick couplers, the ultimate goal is to expedite the process of changing attachments and to maximize productivity on the job site. The right choice will depend on the specific needs of the operation and the types of attachments typically used by the excavator.
We have a great Hydraulic Quick Coupler by Geith. There’s a video on the product page that’s worth watching to understand how the mechanics function internally.
Tilting Quick Couplers
These are newer on the market, but companies are starting to make Tiltrotators and Tilting Quick Couplers. These are very expensive, but drastically increase efficiency by not having to reposition your machine to change angles or digging directions.
All Tilting Quick Couplers must be, by definition, Hydraulic quick couplers as well — since the tilt functionality operates off of hydraulic pressure. So think of Tilting quick couplers as an upgrade to a hydraulic quick coupler.
Geith once again has a Tilting Quick Coupler that we carry, and again I highly recommend just watching the video to see how it works since it’s significantly easier to understand that way
