Attache rapide
A mounting frame between the excavator arm and the attachment that lets the operator change attachments quickly, by hand or from the cab depending on the type.
Quick couplers (also called quick hitches) sit between the excavator arm and the attachment. They let the operator change attachments without driving the pins out by hand, which saves time on sites where one machine uses several tools.
Types of quick couplers:
- **Mechanical**: opened and locked by hand with a lever or spindle (simple, light, no hydraulic lines)
- **Semi-automatic**: opened by hand, locks automatically when the attachment is picked up
- **Hydraulic**: opened and locked from the cab through a hydraulic circuit
- **Tilt-Rotator**: Full 360° rotation plus ±45° tilt (maximum versatility)
Safety standards: Quick couplers must meet ISO 13031 safety requirements:
- Front lock mechanism (prevents drop if rear pins fail)
- Safety springs (maintain lock if hydraulic pressure lost)
- Visual indicator (confirms locked status from cab)
- Connection test procedure (verify engagement before lifting)
Sieruta quick couplers are ISO 13031 compliant and compatible with S40-S100 pin configurations across all major excavator brands.
