Center-Lock Pin Grabber Quick Couplers Pin grabber couplers allow work tools to be changed quickly — improving overall production and increasing machine versatility. A coupler is pinned on in place of the bucket with standard pins, and can be easily removed should the need arise to mount a tool directly to the stick.
The Center-Lock Pin Grabber Coupler is designed for use on machines sized from 311-385 — and is designed to engage and disengage almost every tool designed for these machines.
A new concept in the locking mechanism inside Center-Lock brings many benefits to the operator. A visual secondary lock gives the operator confidence that the coupler is locked, and the patent-pending Over-Center Technology provides a triply redundant locking mechanism. |

Center-Lock™ Pin Grabber Quick Couplers
Overview
Cat® Center-Lock Coupler Highlights
- Cat Center-Lock Pin Grabber Coupler gives operators confidence though its locking system and visible locking mechanism.
- Once Center-Lock has engaged a work tool, the lock is so secure it will stay locked—even in the event of hydraulic failure.
- Should a pin be inadvertently missed, either coupler hook is strong enough to hold the full weight of the work tool on it's own.
- The lock on the front pin of the work tool is clearly visible to the operator, always showing the status of the coupler: open or closed. This gives the operator confidence a tool is engaged, and makes changing tools faster.
- Pin grabber couplers allow work tools to be changed quickly—improving overall production and increasing machine versatility.
- Cat Center-Lock Pin Grabber Coupler is built around the same interface as previous pin grabber couplers and will engage and disengage virtually any Cat bucket or work tool equipped with pins.
- Because engaging the locking mechanism in Center-Lock does not require gravity to actuate. Simplified operation allows quicker tool change regardless of boom or stick position.
