The purpose of the invention is to conceive a supporting unit (1) for a mobile hydraulic crane (9), which should be furnished with an automatically pivotal supporting leg (2), as well as a mobile hydraulic crane (9), which should comprise such supporting unit (1). Said supporting unit (1) comprises a stationary part (31) and a telescopically movable part (32), which is inserted therein and is displaceable along the longitudinal geometric axis (10) of said supporting unit (1), and on which a hydraulically driven telescopic supporting leg (2) is attached pivotally around said geometric axis (10). The invention provides that by displacing said telescopically movable part (32) relatively to said stationary part (31) along said geometric axis (10), said supporting leg (2) is automatically pivoted. To this aim, a probe assembly (5) is mounted onto said supporting leg (2) and cooperates with a template assembly (4).
