A pressurized-medium-driven apparatus including an actuator articulately mounted a line segment and a connecting element. The line segment and the connecting element are connected so as to be mutually pivotable with respect to each other around a swing axis. The connection is provided by a junction means between the line segment and the connecting element, wherewith the connecting element and or the line segment are rigid components, preferably a rigid tube or pipe. The junction means is a swiveling junction connection.

Apparatus driven by a pressurized medium

The invention concerns an arrangement for the securing of an implement to a lifting arm, particularly to a front loader, where the implement and the lifting arm can be fastened to each other by a movable locking bar, which can be moved between a locking position and an unlocking position, and can be brought from the locking position into the unlocking position by a remotely actuated hydraulic cylinder. It is proposed that the locking bar can be arrested automatically in the unlocking position, with it then being possible for the hydraulic cylinder to be deactivated. The locking bar is located such that it can be brought into the locking position from its arrested position by moving the implement by another remotely actuated hydraulic cylinder such that the locking bar engages the lifting arm and is moved to a non-arrested position from where it is automatically biased back into its locking position. Furthermore, it is proposed that the hydraulic actuator for effecting movement of the locking bar be connected with an accumulator.

Arrangement for securing an implement to a lifting arm

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.
