Front loader arrangement with hook-shaped locking bar

摘要

A front loader arrangement includes a bracket, a mounting mast mounted on upper and lower bearings of the bracket, a loader arm which is articulated to a first pivot pin on the mast, a loader support articulated to a second pivot pin on the mast, and a locking device for locking the mast to the bracket. The locking device is arranged on the loader support. The locking device includes a pivoting locking bar which is mounted on a third pivot pin on the loader support, a pre-tensioning device which pre-tensions the locking bar depending on its position relative to the loader support into an open or a closed position, and an adjusting device arranged on the mast which can be brought into engagement with the locking bar, by which the locking bar can be moved into the closed position.
