BLG transports crucible with molten steel

Ship sections weighing 740 tons, scrapped diesel engines or a crucible with molten steel – the heavy-lift cargo specialists at BLG LOGISTICS regularly carry out such special transshipment projects. They then make use of the flexible and maneuverable self-propelled modular transporters (SPMT) made by SCHEUERLE, the developer of these special vehicles for extremely large and heavy cargo and the world market leader in vehicles with hydraulic suspension swing axles.

Various heavy loads are brought from A to B safely and reliably by means of the SPMTs. The transporters are steered via cable and radio remote control by drivers who are specially trained by the manufacturer. The control technology enables precise positioning of even the heaviest loads – an important criterion for these operations as well:

Crosswise with four 10-axle units onto the dock ship
BLG has handled ship sections on the grounds of BVT Brenn- und Verformtechnik GmbH in Bremen-Vegesack, Germany several times already, recently a 540-ton and a 740-ton component for a cruise vessel. The challenge posed by this time-critical job was that both components had to be loaded crosswise, instead of lengthwise, onto the dock ship PAPENBURG because of their dimensions. This made it necessary to recouple the SPMT modules, which presents no problem with SCHEUERLE equipment. The ship sections were initially moved lengthwise from the BVT production building to the quay using two 18-axle units and stored temporarily there. Afterwards the modular transporters were reconfigured and then driven crosswise under the sections using four 10-axle units. After the synchronously controlled SPMTs were turned 90 degrees, the ship sections were finally loaded onto the PAPENBURG. As part of this order, the BLG team with support from the shipping group Harren & Partner also moved ship sections directly onto a ship for the first time, instead of onto a pontoon.

Transport in a convoy
On behalf of Lloyd Werft, BLG handled four diesel engines in Bremerhaven this year. The job involved dismantling the old engines weighing around 115 tons and taking them to a scrapyard. The two SPMT modules used for this purpose were steered in a convoy. During the approx. four-hour transport operation several sections of road had to be blocked off in Bremerhaven. The shipment took place with a police escort via the BLG Auto Terminal in Bremerhaven to the scrapyard located behind it. BLG transported the new engines, weighing 70 tons each and generating the same power, via Mafi trailer to Lloyd Werft.

Hot crucible on wheels
On behalf of the Schmidbauer Group, a systems service provider and specialist in the heavy-lift sector, BLG moved a crucible with molten steel having a temperature of 1,500 degrees on the grounds of Salzgitter AG in September. The crucible weighing around 290 tons had to be moved somewhere else in the production building because of installation of a new crane. Several test runs took place in Salzgitter. To protect the SPMTs against the great heat of the crucible, it was necessary to make a heat shield acting as a kind of saucer. The crucible was placed directly on this heat shield by means of a crane.

It is not the first time that the special vehicles belonging to BLG were in operation outside Bremen and Bremerhaven. Since SCHEUERLE SPMTs can be shipped on trucks as well as on container flat racks, they are deployable as mobile equipment worldwide.

Confidence in the world market leader
As far as its SPMTs are concerned, BLG LOGISTICS trusts in SCHEUERLE’s experience. The company, which now belongs to the TTI Group, developed the first special vehicles of this type in 1983. The TTI Group is the world leader in the production of self-propelled modular vehicles and has by far the biggest vehicle fleets in this segment of the global market.

The heaviest component transported by BLG up to now is a foundation platform for an offshore wind farm that weighed about 1,800 tons. Apart from the actual transport of XXL products, BLG also performs comprehensive system services for its clients in the procurement, production and distribution logistics sectors. By means of a computer program, BLG’s Engineering Department can simulate in advance whether the necessary stability can be guaranteed for the entire route – as was the case in transporting the ship sections. Cargo and environmental data as well as axle load and stress analyses are taken into account in the simulation. BLG’s own terminals featuring heavy-lift cargo capability round off the range of services offered.
