Title
(EN) l-LOCK COUPLER
(FR) COUPLEUR DE VERROUILLAGE EN L
Abstract
(EN) A quick coupler which features a safety mechanism which facilitates ease of use and assures safe use in the workplace by use of hydraulic circuits designed to automatically reset the safety locking mechanism on intentional removal of a front pin, including use of a 2-line hydraulic supply to the coupler.
(FR) L'invention concerne un coupleur rapide comprenant un mécanisme de sécurité qui facilite l'utilisation et assure une utilisation sûre dans le poste de travail par l'utilisation de circuits hydrauliques conçus pour réinitialiser automatiquement ledit mécanisme de verrouillage de sécurité lors du retrait intentionnel d'une broche avant, comprenant l'utilisation d'une alimentation hydraulique à deux conduites au coupleur.
