Sisu Terminal Systems

Sisu Terminal Systems Oy (STS) was a Finnish terminal tractor producer. The production began in 1969 as a part of Suomen Autoteollisuus (SAT) and the first vehicles were based on lorry components. The portfolio grew by time. The production facilities were in Hämeenlinna until the mid 1990s, when they were moved to Tampere. The company produced terminal tractors also in Texas under the name ''Magnum'' in 1987–2005.

STS became a limited liability company in 1994 and was sold and restructured in 1997. Subsequently, the ''Sisu'' brand was replaced by ''Kalmar''.

History

Initial development

The first four prototypes were produced in 1969. The vehicles were type T-9SV and they were largely based on Kontio-Sisu lorry components. The customer was stevedoring company Oy Åkerman Ab.

In 1970 SAT started a development project jointly with consulting company Jaakko Pöyry for suitable vehicles for loading and unloading of ro-ro vessels. As a result, SAT launched a four-wheel-drive model TV-10 and its reversed steering version T-10 in 1971. 22 units were produced in the same year. A significant feature was its patented fifth wheel coupling system which enabled a quick a flexible engagement. The solution was developed by technician Nils Fagerstedt and it paved the success in export market.

After the promising start, the model selection was extended gradually; rear-wheel drive TV-12 came in 1974 and 4×4-model T-13 in 1977.

Creation of the business unit

DI Christer Schalin was appointed the Production Manager of the terminal tractor production line in 1979. He had previously worked as the Export Manager of SAT and started now to work hard to develop the terminal tractor business. Schalin expanded the export market and he also created the Sisu Terminal Systems name and logo.

Breakthrough

In autumn 1980, Sisu TR-200, which was the world's strongest terminal tractor by then, was presented in Portex fair in Hamburg. The Sisu terminal tractors could be designed relatively easily according to the customer requirements due to highly modulised structure; this led to success in export markets in particular.

As the capacity of the Hämeenlinna factory could not meet the need time to time, some units were assembled in the Karis factory.

Magnum and Ottawa

Sisu-Auto founded a new terminal tractor factory in White Oak, Texas in 1987. The main responsibility of the project was on Heikki Luostarinen who later became the company General Manager.Blomberg (Suomalaista...): ''Heikki Luostarinen: Sisun tekninen osaaminen varmisti yrityksen jatkuvuuden.'' p. 229–234. The vehicles were branded first ''Sisu'', later ''Sisu-Magnum'' and at the end just ''Magnum''. The factory was closed down in 2005 and production of Magnum terminal tractors was continued in other facilities.

In 1993 Sisu-Auto acquired Ottawa Truck Corporation which was its main competitor in North American market. Some trucks were sold with combined ''Sisu'' and ''Ottawa'' badging.

Organisational changes

The terminal tractors were separated from the other vehicle production under its own organisation in 1989. In 1991 Sisu Terminal Systems division was founded for the RoRo equipment manufacturing.

When Sisu Corporation was created as a consequence of merger between the owning Sisu-Auto and Valmet wheeled machines, STS became a limited liability company ( Oy). As a part of the following restructuring the production was transferred gradually to former Valmet facilities in Tampere. The last terminal tractor produced in Hämeenlinna rolled out from the factory in January 1996.

The terminal tractor production totalled about 2,600 units by the production transfer. The vehicles produced in the Karis factory are included into the figures. In addition, hundreds of gooseneck trailers and other container carriages were produced.

A new acquisition followed in 1997 when Partek took over Sisu Corporation. At the same time Partek bought the Swedish container handling equipment producer Kalmar Industries, into which STS was joined. Use of ''Sisu'' brand on terminal tractors was discontinued thereafter, and the name kept on living as a lorry producer.
