Boost Productivity

  • Get back to work faster with the capability to change attachments in seconds
  • Attachments are shareable between similar sized excavators
  • Couplers are weighted to handle big payloads, so you do not have to compromise on bucket size
  • Do more with your equipment. Added versatility allows you to switch easily from digging, grading, material handling, compacting soil, breaking rocks, and more.
  • Trenching widths available for certain coupler sizes:
    • Saves backfill time and material
    • Keeps the widest part of the coupler inside the digging width of 24- and 30-inch buckets
    • Fully compatible with wider buckets and the same attachments as the standard models
  • Pin Grabber Performance Buckets – recessed pins for an even further reduced tip radius
  • Pick up buckets in reverse position to clean out square corners

Reliable Power and Strength

  • Redundant locking system secures attachments:
    • Primary wedge – Blocks pin movement like a deadbolt lock
    • Secondary latch – Indicates to operator if coupler is either open or closed. Hinged to clamp the pin in place.
    • Two spring-loaded arms – Assure secondary latch stays closed
  • In the event you experience a loss of hydraulic pressure, redundant locking systems keep attachment in place
  • Short coupler profile maintains tight tip radius, breakout force, and digging power
  • Cast frame pieces made from abrasion-resistant steel
  • Integrated, centered lift eye handles wide range of shackle, chain, and cable. Its interior shape keeps loads stable.
    • Couplers without a lift eye are available in Japan to meet local lifting restrictions.

Top-of-mind Safety

  • Visual and audible indicate to operator attachments are secure to the coupler.
  • Greasing block provides a primary and easily accessible grease point.
  • Operating procedures are simple and intuitive.
  • Compliant with worldwide safety standards: ISO13031, EN474, and AS 4772:2008.
  • Simplify on-the-job maintenance and improve reliability with the debris shield covering and protecting critical coupler components.

Boost Efficiency and Productivity with Integrated Technologies

  • Never waste time looking for your couplers again. Cat asset tracking is available on select Pin Grabber Couplers.
  • Track your entire fleet of attachments and machines from one source. Couplers with asset tracking can be viewed in VisionLink®alongside Product Link™subscribed equipment.
  • Keep your assets secure. Couplers with an asset tracker send an alert if they leave an easy-to-setup site boundary.
