The JRB PowerLatch multi-pin-grabber coupler by Paladin, designed by Miller UK Limited, is one of the safest, most advanced multi-pin-grabber couplers available for excavators and loader backhoes. It employs several advanced safety features, including a patented Automatic Blocking System (ABS) that ensures coupler engagement is maintained during hydraulic failure. The JRB PowerLatch features backup mechanical locks on both the front and rear attachment pins that are independent of the machine’s hydraulic locking and operating system. The ABS mechanical backup safety system automatically locks both pins so coupler engagement is maintained even if hydraulic failure occurs. If the rear bucket pin is not correctly engaged, or missed during the attachment process, the ABS automatically secures the front attachment pin. Attachments can only be removed under operator control when they are in a safe, curled position – preventing accidental release of the attachment. In addition to its advanced safety features, the coupler includes reduced offset that allows for greater breakout force. Ports connecting the hydraulic hoses to the coupler are located on top of the cylinder, making installation much easier.
