Pin Grabber Coupler – Trenching Profile (TB-Linkage): 390-0904

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.

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.
