HKM QC30 Quick Coupler

QC30 Quick Coupler

The QC30 model Quick Coupler is engineered for excavators in the 30 to 35 ton range. With a working weight of 550 kg, it provides a solid and safe coupling solution for heavy-duty equipment. The coupler's body dimensions: 1100–1200 mm in length, 630–640 mm in height, and 530–570 mm in width enable it to handle large attachments with confidence. With a pin diameter of 90–100 mm and a pin center axis distance of 390–420 mm, QC30 ensures compatibility with a broad range of heavy-class machines. Operating at 30–40 bar pressure and requiring 10–20 L/min oil flow, it supports high-performance, field-proven operation.
