What is the quick coupler? How does it operate?


A quick hitch coupler, also referred to as a quick attach coupler, is an accessory that enables you to swiftly and effortlessly switch between different fittings of an excavator or other large machinery.


The primary benefit of using a quick attach coupler is speed and ease. It eliminates the need to go through each step of removing, adjusting, aligning, re-tightening, and refilling repeatedly, allowing you to quickly change between fitting types. Without a quick hitch coupler, this process can take up to 45 minutes for most excavators. However, with a Quick Hitch coupler, you can complete the entire process in as little as 10 seconds!

How do I select the appropriate quick hitch coupler?


To ensure maximum safety and efficiency, it's important to choose a durable quick hitch coupler that can withstand the weight and pressure of your machine. When making your selection, consider how often you will be using the coupler. Frequent use requires a heavy-duty unit, while occasional use may only require a lighter-duty model.


Before selecting a quick hitch coupler, it's essential to determine your machine's horsepower and maximum operating pressure. Coupler sizes vary depending on these factors, so it's crucial to match up your equipment's specifications with those provided by the manufacturer. This ensures the coupler is appropriate for your machine and can operate correctly.

2. Is there any information to be aware of following installation?

Once you have installed a quick hitch coupler, it is important to ensure that all nuts and bolts are properly in place and tightened securely. Additionally, if your machine has a filter system, it's essential to keep it in good working order to ensure it operates smoothly.


3. Why should I invest in an excavator quick hitch coupler?

Using a quick hitch coupler saves time and is a safer alternative to the traditional method of re-tightening each attachment after use. In fact, the quick hitch coupler is an excellent safety feature that not only prevents attachments from falling off but also helps prevent them from coming loose in the first place.


With an excavator bucket quick coupler, various attachments such as a bucket, hydraulic breaker, plate compactor, log grapple, ripper, and more can be quickly connected to excavators. This expands the scope of use for excavators and can save time while also improving working efficiency.

4. What are some common misunderstandings about using one?

Many people believe that quick hitch couplers are only essential if they frequently switch between different attachment types. However, this is not entirely true. Even if you need to switch between two digging attachments of the same type, you can still benefit from a quick hitch coupler since it allows for a quick and easy changeover.

5. Is there a weight limit for quick hitch couplers?

Quick hitch couplers are usually capable of carrying loads weighing between 10 to 70 tons, while some heavy-duty couplers can lift up to 90 tons. It's important to keep in mind that the strength of the coupler directly affects its weight, so it's crucial to ensure that your machine can handle the weight of the coupler you choose.
