摘要

An upturning device (3) for jack arms (1) in crane-carrying lorries comprises a torque generator (11), arranged coaxially inside a hollow pivot (10) linking the jack arm (1). The torque generator has a rotor (12) which is integral with a linking head (8) of the jack housing (5) and a stator (16) that is coaxial and internal to the rotor and is torsionally connected to a linking plate (2) bearing the hollow pivot and is rigidly connected to one end of a supporting crossbeam (4). Preferably, the torque generator is hydraulic and comprises of a semi-rotary alternative actuator contained in the cavity of said linking pivot (10).
