The Rockland HKR Excavator Coupler is one of the worlds safest couplers. It features twin locking, high visibility, cast steel hooks with two powerful alloy springs which guarantee the coupler will hold attachments - in the event of a hydraulic failure. An additional safety feature of the HKR is the exclusive patented Smart Valve which is part of the cylinder. This safety feature only allows the coupler to function while fully curled close to the machine. For more information on the revolutionary HKR Coupler click HERE.

  • Picks up largest range of pins.
  • Will only release attachments while in the fully curled position.
  • Spring safety system will not drop attachments even with complete hydraulic failure.


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