The unit is fully compliant with ISO 13031, EN 474, AS 4772 safety standards. The design features a rear wedge to keep the rear pin secured without relying on gravity, preventing a swinging attachment in the event of a hydraulic failure. And, a hydraulic check valve has been added to maintain pressure in the cylinders in the event of hydraulic hose breakage until proper function is restored. The coupler’s internal safety-lock is spring-engaged and hydraulically released to keep the rear wedge in place, securing the pin. To prevent accidental attachment drops, the hydraulic interlock requires the coupler to be fully curled towards the cab before it can be disengaged.
