The Caterpillar Center-Lock Pin-Grabber coupler for Cat hydraulic excavator models 311 through 385 uses an over-center locking mechanism and two hydraulic locking features to assure positive work-tool attachment. The over-center locking technology promotes jobsite safety and allows operators to quickly, simply and confidently engage and disengage work tools regardless of boom and stick position. The Center-Lock coupler accommodates the same range of Cat work tools as previous pin-grabber couplers, as well as a broad range of other brands of buckets and tools.
