Quick Attach Units

Most versatile quick coupler system. Rugged QT100 construction. Wide coupling range. Simple and safe to operate.


  • Super Heavy Duty Construction – Nye QAU (Quick Attach Unit) pin-grabber style couplers are designed for severe service in the most extreme construction, demolition and quarry applications.
  • Super thick front hooks – Resist flexing and provide extra wide pin contact area.
  • Alloy Steel – 120,000 psi quenched and tempered alloy steel front hooks eliminate deformation and breaking.
  • Double slotted hooks – Rear hooks are milled, providing 4 oversize flat sliding surfaces to endure the harshest pounding in dusty, gritty conditions.
  • Alloy clamping screw – Oversized alloy main clamping screw is virtually un-strippable. Provides years of trouble free, safe operation.
  • Base Plate Design – Eye plates and hooks are welded to a common foundation base plate eliminating breakage due to clumsy weld joints used on staggered side plate designs.
  • Easy to Service – The clamping screw, locking mechanism and main nut are easy to service without special tools or equipment. There are no slider pins to service, no inspection covers to remove and no springs, linkages or roll pins on the coupler.
  • Easy Installation – Just pin the coupler onto your machine with the factory bucket pins. Coupler is manually operated; no hydraulic or electrical installation is required.
  • Simple operation – Couple, uncouple and lock the coupler with one socket wrench (provided). There are no locking plates or fasteners to fumble with and loose.
  • Redundant safety – All Nye couplers feature a manually inserted safety bar that eliminates any chance of accidental uncoupling.
  • Open Design – Un-shrouded rear hooks provide excellent visibility for inspection and operator verification of hook engagement. Dirt and stones fall away and do not get impacted.
  • Lifting Lugs – Integral lifting lugs provide a convenient shackle point for heavy lifting.
  • Guaranteed – Like all our products, the Nye Mechanical QAU is guaranteed to please and covered by our limited warrantee.
