The device mounted at the end of an operating arm comprises one or more suckers for supporting objects, for example refractory bricks for the brick-lining of a metallurgical converter, means for linear and angular displacement of the suckers, sensors for monitoring and controlling automatically the means of displacement in order to grip and position the objects in a predetermined location, after immobilization of the operating arm. The suckers are provided on a sucker-carrying plate which in its turn is supported by a pair of blocks which can slide in transverse slide bars of a carriage which comprises a pair of longitudinal slide bars, perpendicular to the transverse slide bars and housed in sliding fashion in a central support attached to the end of the operating arm with a degree of angular freedom and a degree of linear freedom orthogonal to the axes of the longitudinal and transverse slide bars.
