The invention relates to a moving walkway transporting people on a grooved surface included in pallets (1) having the same pitch as the traction chain, all of them being able to be attached by means of pins (2) forming the actual traction chain between them, in which the pallets (1) are overturned by means of a guide (3) in which only three pallets are located, causing a quick overturning allowing the comb (5) to have sufficient inertia in its ribs (6) so as to support the loads which the users will apply to it in the direction (4).
