Compared with a traditional quick coupler, we add another auto-lock on its front hitch ensuing double safety. Independent hydraulic system, the front lock still works well even when inner leakage happens. The front lock will lock the pin from dropping off when the rear tiger mouth or cylinder rod broken.
