Quick-attach Coupler

From RitchieWiki

Mechanical Features and Designs

A quick-attach coupler is a coupling mechanism whereby attachments can be quickly switched relatively fast and efficiently on a piece of equipment that utilizes a pin-on type of attachment system thereby giving the machine double-duty functionality and added versatility.

Both mechanical and hydraulic quick couplers exist.[1] With mechanical couplers, the operator must switch the attachment manually. The hydraulic coupler, on the contrary, works to pick up the tool and establish a hydraulic hose connection simultaneously without the operator having to step out of the cab of the machine. The huge advantage of this feature is it increases safety and enables the changing of attachments with relative ease out in the field. One machine with a few attachments can be used on the job site as opposed to having to haul more than one machine to do multiple tasks.[2]

Quick-attach couplers have some limitations. Attachments on these couplers usually extend out further, resulting in a reduction in breakout force. The constant coupling and uncoupling of attachments also tends to lead to greater wear and tear on pins than on a direct attachment pin-on and places the machine at a greater risk for contaminant ingestion every time a hydraulic line is removed or reinstalled.[3]
