  • Front Lock - Hooks to a front pin
  • Rear Lock - Extends to engage on rear pin
  • Dead Lock - Activated when the cylinder extends into its final position and locks the front lock in position; Dead lock saddle-machined into side plate of coupler prevents the front hook from disengaging the pin unless the cylinder is retracted under hydraulic pressure


  • Pilot operated check valve ensures cylinder can only be operated when hydraulic pressure is available
  • Integrate pressure sensing system on the bucket curl circuit ensures that the attachment can only be released with positive hydraulic pressure
  • The spring ensures that even in the event of complete hydraulic failure the front latch cannot release
