QC03 Quick Coupler
The QC03 model Quick Coupler is specifically designed for compact excavators in the 2.5 to 3.5 ton class. With an operating weight of 35 kg, it delivers a perfect balance of strength and agility. The coupler’s body measures 430–460 mm in length, 270–300 mm in height, and 230–290 mm in width—ideal for use in confined workspaces. The pin diameter is 30–40 mm, and the pin center spacing is 170–180 mm, offering reliable compatibility with most compact excavators. Operating at a hydraulic pressure of 30–40 bar and requiring an oil flow rate of 10–20 L/min, QC03 ensures smooth and safe attachment changes in the field.
