Abstract: The present invention relates to a modular installation for controlled transport of parts or products. This installation includes at least one autonomous pallet (10) carrying a traction mechanism, preferably in the form of an electric motor-brake (14), this pallet being provided with wheels (15, 16, 30, 31) for circulation on a rail network, conveying the motor feed current and the control signals for the traction mechanism of the pallet. The pallet comprises two girders (11 and 12) and a plate (13) provided with two centering pins (21). The installation is advantageous in that it is flexible and allows an adaptation to all utilizations, especially because the pallets may be managed individually by a central data processing unit.
