Abstract
The invention pertains to a device for attaching an implement to a lifting unit, in particular, to a front-end loader, wherein the implement and the lifting unit can be connected to one another by a movable bar that can be displaced from a locking position into an unlocking position by an externally activated actuator. The actuator is coupled to the bar by a coupling device designed such that a driving connection between the actuator and the bar is only produced when the actuator is activated. This makes it possible to displace the bar manually, as well as in an actuator-operated fashion.
Claims11
In a combination including an implement releasably coupled to an implement holder carried at a forward end of a lifting unit of a front-end loader, and a releasable coupling device associated with said implement holder including a transversely extending, J-shaped bar movable between locking and unlocking positions for respectively securing said implement to, and releasing said implement from, said implement holder, the improvement comprising:
- an extensible and retractable actuator having one end coupled to said implement holder;
- a coupling device connected between a second end of said actuator and said bar so as to establish a driving connection between said actuator and said bar only when said actuator is activated for establishing an unlocked condition in said bar.
