ESCO Corporation, a global provider of wear parts and attachments for the mining and construction industries, has developed a new hydraulic coupler that gives machine operators a simple connection to attachments and provides enhanced site safety.
The ESCO PosiGrab coupler features both front and rear locks that are mechanically engaged through the full working cycle. The natural position of the coupler is locked and only opens using forced hydraulic pressure.
The connection and release of an attachment, including the visual confirmation that the locking mechanisms are engaged, is done without the operator leaving the safety of the cab.
Along with the safety and ease-of-use benefits, PosiGrab coupler was engineered to reduce stress on attachments and machines.
