Both manual and Hydraulic actuated versions are available. The hydraulic circuit is available as a retrofit kit dedicated to this coupler. Buckets can be reversed for greater flexibility when working around and under obstructions.
  • The dedicated Pin-Lock is a hook and pin type interface which features a locking mechanism to ensure a secure fit. Buckets and tools with the matching interface can be changed in about one minute and require one pin (manually inserted into the coupler) to couple tools into place. The Pin-Lock dedicated coupler pins onto the stick, allowing the machine to pick up new and old style competitive work tools that have Pin-Lock style pockets. These tools include buckets, hammers, rippers and augers.
  • Tilt-Lock couplers have the same functionality as the Pin-Lock coupler, but with the added benefit of the tilting function. This functionality precisely positions a work tool based on the work demands. This is key for backfilling, ditch cleaning, grading and sloping operations.
  • Dedicated Wedge-Lock couplers are considered the standard when talking about dedicated couplers on hydraulic excavators. This coupler design provides excellent durability in the most demanding applications. A range of buckets, hammer/compactor brackets, grapples and other tools are available for this coupler style.

Tool Control
The integrated Tool Control system allows for five pre-set combinations, eliminating the need to re-set the hydraulic parameters each time a tool is changed. Individual flow and pressure can be programmed easily as well as one-way/two-way hydraulic functions. Each of the five programmed tools can even be given a specific name via the monitor.
