The operation of unloading profiles takes advantage of the declination of the aerial transporter. Coated profiles, which arrive vertically hanging, are supported by a special chain that accompanies them until the lowest point of the transporter, where profiles shall be unhooked by hand. The upper extreme of this chain is bolted in the same stage where profiles start descending; on the other hand the lower extreme may adapt its position to the length of profiles in order to be easily unhooked.
