• This rail 13 is generally located directly downstream of the downstream transfer zone.
• Such a configuration of the displacement means 8 is particularly advantageous, insofar as, due to the superposition of the rails 10, 11, it occupies little space on the ground and allows an operator to intervene easily (especially compared to a displacement means forming a closed loop circulation) without imposing a reduction of the rate.
