HKR Excavator CouplerHKR Excavator Coupler

One of the key safety features of the Rockland HKR excavator coupler is shown in the diagram to the left. The built in "smart valve" prevents release of the attachment until the coupler is fully curled and in the release zone. This valve insures proper and safe operation.

The HKR coupler also features high visibility, cast steel locking hooks that are locked into position by two alloy springs. These springs create a fail safe retention system.

 

  • The ultimate test - An HKR coupler with bucket was installed on an excavator operating in a rock quarry. Both coupler hoses were cut to simulate a complete hydraulic failure. A month later the quarry needed to change buckets - they had to remove the coupler first.



Description

  • Unique springs insure that the pins will not release even in the event of complete hydraulic failure.
  • Cast steel hooks provide strength to endure the toughest applications.
  • Smart Valve assures proper and safe coupler operation.
  • Quick and easy installation.
  • Dual cast steel hooks assure proper pin retention under all circumstances.

Warranty

Rockland HKR Couplers are guaranteed against failure due to defective design, materials, or workmanship for a period of one year or 2,000 hours.
