Product
The STEC QC quick coupler is a mechanical or hydraulic coupling system for excavators. It connects buckets, grapples, rippers, and other attachments to the machine boom.
All our quick couplers are equipped with a certified lifting hook and hydraulic check-valve. The quick coupler is also fitted with safety pins that secure the front shaft of the work tool, reducing the risk of the tool dropping during operation.
