Quick Couplers

Quick couplers enable safe switching between attachments in seconds. They save time on site and increase machine utilization.

HKM quick couplers speed up hydraulic attachment changes, enabling efficient work with fewer people on site. The 11 models from QC02 to QC60 fit 1.5-60 t excavators and deliver long-life performance with wear-resistant manganese-steel bodies and honed hydraulic cylinders.

A spring-loaded retaining disc and dual-lock pin system prevent accidental attachment release. Fully compatible with all leading excavator brands, they let you switch quickly, practically and safely between breaker, auger, bucket, concrete cutter and more.

Will it fit your machine?

Enter your excavator tonnage to see which Quick Couplers models fit your machine. Narrow it further by oil flow if you wish.

This tool performs a pre-selection based on catalogue values and is not a binding quotation. Attachments without a hydraulic supply, such as rippers, have no flow or pressure rows; those models are unaffected by the flow filter. The final choice is made together, based on material, workload and the hydraulic equipment of the carrier.
