In the Spring of 2021, Transportes Muciño (Transportes Muciño, S.A. De C.V.) performed a groundbreaking transport on an extremely challenging route in Mexico. Two major components weighing 380 and 320 t respectively had to be moved from the port of Tampico to the Tamazunchale II power plant, on behalf of Mitsubishi Power Americas, Inc. This challenging transport could not have been performed safely without the Goldhofer ADDRIVE and the all-new ADDRONIC.
Tamazunchale II is a 514 MW gas-fired power plant under construction in the Mexican state of San Luis Potosí. The heaviest component was a generator weighing 380 t and measuring 10.2 x 5.4 x 5.4 m. Since the route included multiple obstacles, conventional heavy-duty module combinations were not feasible. With the trust of its client, Transportes Muciño turned to the equipment from Goldhofer to perform the job.
“Mitsubishi placed their trust for this challenging job in us. For us, transportation is about teamwork, so we wanted a partner we had worked with in the past: a value that Mitsubishi, Muciño, and Goldhofer share. That is why we decided to face this project with Goldhofer,” said Raúl Cuevas, commercial director at Transportes Muciño.
Inclines of up to 19%, hairpin turns, and narrow roads posed a challenge. In the end, multiple combinations of Goldhofer heavy-duty modules and the FAKTOR 5 high girder bridge were put to use. The gross weight without trucks was up to 705 t.
“With ADDRONIC, the basic functions such as steering, leveling, and drive of up to 4 ADDRIVE modules can be synchronized. In addition to that, the integration of an existing fleet into the transport combination can be realized easily,” said Rainer Auerbacher, head of Transport Technology at Goldhofer.
Starting with a 2x18-axle line combination with 1 pushing and 2 towing trucks, the 2 modules supported the combination. At the city of Jaltocan, the Muciño team reconfigured the convoy to a 2x9-axle parallel combination with 4x6-axle line modules. The 3 tractors and the modules handle inclines of up to 14% on extremely narrow roads. With detached tractors, the convoy traversed over 46 hairpin turns, even passing a 54° bend in Chapulhuacanito. After another reconfiguration to a 2x12-axle line parallel combination, the Muciño team made their way to the power plant. For the last mile, the synchronized ADDRIVE modules once again played to their strengths and independently moved the convoy through a 19% decline to its final destination.
More than 126 curves were expanded, and 6 major bridge reinforcements had to be made along the route in order to accommodate such a large configuration. Some of the bridges even had to be crossed without trucks in order to reduce the total weight and avoid long detours. Under the leadership of Mitsubishi’s logistics team, Transportes Muciño spent over 16 months preparing for this project.
