- Tips & Tricks
- Heavy Equipment How Tos
There are dozens of options for excavator attachments. Some are pretty straightforward, but others are more open-ended and could be used in various ways. Depending on your industry, you might have particular needs for an attachment.
You’ll also find that attachments can go by many names, which change based on region and job site.
So here are some standard excavator attachments, what we call them, and how we’ve seen them used.
Couplers for excavators, also known as quick couplers, quick connects, or quick hitches, are mechanical or hydraulic devices that attach excavator attachments quickly. They make it easier to connect and disconnect different attachments, such as buckets, hammers, and other tools, to what’s sometimes referred to as the excavator's arm or the stick.
Check out this overview of hydraulic couplers:
Types of Couplers for Excavators
Mechanical Couplers: Mechanical couplers are manually operated and use pins or latches to secure the attachment to the excavator. The operator manually inserts the pins or engages the latches to lock the attachment in place. The operator must manually disengage the pins or latches to release the attachment. Based on the size of the machine, it can take more than one person to disengage the pins. If it’s an especially large machine, a sledgehammer might be involved to get the pin out. So on larger machines, we’d suggested a hydraulic coupler to make things more efficient.
Hydraulic Couplers: Hydraulic couplers use hydraulic cylinders to connect and disconnect attachments from the excavator. The operator can control the coupler from the cab, engaging or disengaging the attachment without leaving the operator's seat.
Advantages of Using Excavators Couplers
