Abstract
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.
