Developed for ease-of-use and operator safety, ESCO's latest innovation — the ESCO PosiGrab II hydraulic coupler — has undergone extensive testing and benchmarking against similar products.

A key feature is independently secured front and rear locks that provide redundant retention security. The natural position of the coupler is locked and only opens when hydraulic pressure is applied. Specifically, the coupler will remain locked in the event of hydraulic system failure or a severed hydraulic hose, according to the manufacturer.

The new design includes a weight reduction averaging 12 percent over previous ESCO models.

The PosiGrab II coupler is a multi-pin design that enables engagement with the range of buckets and attachments within a given tonnage class and can be fully operated, including locked confirmation, from the comfort and safety of the machine operator's cab.

The PosiGrab II coupler, when properly matched with OEM (Original Equipment Manufacturer) excavator buckets and attachments, will provide a safer and more reliable attachment engagement and change-over of various implements for maximum machine productivity and versatility, according to the manufacturer.
