QC05 Quick Coupler
The QC05 model Quick Coupler is designed for excavators in the 4 to 5 ton class. Weighing 60 kg, it delivers both durability and ease of use, making it ideal for medium-duty work. The body dimensions—540–550 mm in length, 300–310 mm in height, and 290–325 mm in width—make it compact enough for confined environments while offering stable coupling. The pin diameter is 40–50 mm and the pin center axis distance is 200–210 mm, allowing full compatibility with leading excavator brands. Operating at 30–40 bar hydraulic pressure and requiring 10–20 L/min oil flow, QC05 ensures safe, quick and efficient attachment switching.
