[4] In 1995, Nicolas Industrie joined the group, followed by Kamag Transporttechnik [de] in 2004 and TII India, which is represented by the brand Tiiger, in 2015.

Rettenmaier had already been active as an entrepreneur: He expanded his parents' mill business to become the world market leader in the production of wood fibers (cellulose).

[9] After the successful restructuring of Scheuerle Fahrzeugfabrik, Rettenmaier bought the French competitor Nicolas Industrie in 1995, which also produced heavy-duty vehicles.

To create the legal and organizational conditions for further growth, a holding company called Transporter Industry International was established.

Due to the insolvency of Kögel Fahrzeugwerke [de], the subsidiary (Kamag Transporttechnik) specialized in smaller industrial vehicles and modular transporters had to be sold.

With the takeover and integration into the holding company, Rettenmaier completed the product range of Transporter Industry International.

[11] In 2015, Transporter Industry International acquired the civilian sector of the Indian trailer manufacturer Tratec, thus securing its first local presence outside Europe, with access to emerging markets in Asia; subsequently, the company was renamed.

[12] Transporter Industry International (TII) operates as a private limited company (Gesellschaft mit beschränkter Haftung) with its headquarters in Heilbronn, Baden-Württemberg, Germany.

The Solid Rocket Motor (SRM) transporter, for example, moved the Space Shuttle segments between refurbishment and storage facilities on the Cape Canaveral Air Force Station and the Vehicle Assembly Building.
