Train transfer table TDB series

Overview
The bogie transfer table is used to remove/install a bogie of a tram or a train lifted by column lifts. There are two capacities: 6 tons and 8 tons. Both models have a U-shaped cutout allowing operators to access under the bogie during removal or installation. SEFAC offers this tailor-made configurable solution.
