QC-PG - pin-grabber quick-coupler for factory brackets
Pin-Grab - pin-grabber type quick-couplers
- 0.9–40 tons
- On request
Pin-grabber quick-coupler using factory brackets: it picks up the excavator manufacturer’s own bracket, and the variable pin-centre models let one coupler take many different OEM attachments. Fully automatic hydraulic (QC-PG), mechanical by wrench (QC-ML-M, wrench included) and hydraulic tilt/swivel (QC-U-PG) versions are available across ten sizes, from 0.9 t carriers to 40 t machines.
