A transport carriage for industrial plants comprises a bearing structure mounted on a plurality of wheel units pivoting around respective vertical axes. The wheel pivoting units are connected by means of kinematisms to a single control plate mounted articulated around a vertical axis. The control plate may be maneuvered by means of a steering unit including a steering plate which is mounted articulated around the same articulation axis of the control plate. The steering unit is provided with a vertical bar suitable to be engaged into a hole of the steering plate and into any one among the two holes of control plate (5) to join the plates integrally in the rotation around the articulation axis thereof. When the engagement member is inserted into the abovementioned first hole, the wheels of the carriage are prearranged for movement in the normal advancement direction, with the possibility of steering within a limited angular field. When the engagement bar is inserted into the second hole the steering unit may be maneuvered over a greater angular field, which allows directing the wheels of the pivoting units in an orthogonal direction with respect to direction A. |
