An excavator quick coupler (also known as a quick hitch) is an attachment designed to allow efficient and rapid switching of excavator attachments. It is a device that attaches to the excavator arm and allows the operator to connect and disconnect various bucket and attachment types, such as hydraulic tilt buckets, hammers or rippers, with ease and speed, without requiring operators to leave the cab.
Compared to traditional hitch systems that require manual labor to reposition and secure attachments, quick couplers increase the speed of operation and can save significant amounts of time and labor costs on job sites.
Excavator quick couplers come in different styles, including mechanical, hydraulic, and fully automatic. Mechanical couplers utilize a manual locking mechanism that engages and disengages the attachment with the bucket pin. Hydraulic couplers utilize hydraulic cylinders to clamp and release the attachment, while fully automatic couplers use sensors to lock and unlock the attachment automatically.
Quick couplers are widely used in construction, mining, and any industry that requires the use of an excavator. They come in different sizes and types that fit different types and sizes of excavators, making it easy to interchange different types
of buckets and attachments.
