These loads are accompanied by personnel to handle the elevations (maximum 500 mm.) and shifting (500 mm to the right and 500 mm to the left). The transport of boilers are normally within tha gauge established by Renfe and the net load capacity in 275 tons. In the picture; a.- 125 T. cross beam transformer. b.- Transportation of a 145 T. caged turbine.
