The S-Lock System was designed to be fully compatible with the internationally adopted S-Standard adapters. In addition to a
specially engineered, centrally located locking mechanism, the S-Lock coupler features a second locking mechanism at the front
pin, providing a twin lock system for maximum safety.
The hydraulic quick coupler enables an efficient and safe mounting of the attachments without manual work at the coupler itself. The spring loaded locking pins take care of a force-fit and playfree connection.
