Geith G3 hydraulic quick coupler features four independent safety components, and the double locking, fully automatic quick coupler configuration complies with the impending safety standards set forth by ISO/FDIS 13031:2013(E). The front safety lock retains the attachment in the event of improper link/rear pin connection, while the front safety lock and the mechanical secondary rear safety system—independently—retain the attachment in a working position should a loss of hydraulic power occur. Unlike gravity-type systems, both the front and the rear spring-retained safety locks maintain high functionality in severe and dirty environments, Geith says. The quick coupler’s curved engaging plate, or pin seat, holds the attachment’s link/rear pin firmly in place upon a loss of hydraulic power. In addition, the G3 quick coupler features a hydraulic cylinder check valve, as well as the Geith-patented “curl to release” control system, providing a safe process for attachment engagement and release. It is manufactured using extra-high-strength.
