The beginning of AAT Alber Antriebstechnik GmbH can be traced back to the swabian company Haas & Alber Haustechnik und Apparatebau GmbH. The first idea to develop a motor-driven hand truck grew out of the experience gained by the owner of the company who worked in the plumbing and electrical industries. In 1982, a patent was applied for the "hand truck with stair climbing device". The first product, the CargoMaster, was born.

In 1986, a stair climber was developed which made it possible to transport wheelchairs up and down stairs - the scalamobil was created. After the patent for the "stair climbing device for wheelchairs" was registered, the scalamobil was introduced to the market in 1988.

In 1995, the company was sold to Triumph Adler AG and the business segment "transport technology" was excluded from the company. At the same time, the company AAT Alber Antriebstechnik GmbH was founded. In addition to the distribution and further development of the CargoMaster products, the new in-house R&D department also developed products for other companies, including the viamobil pushing and braking aid as well as the e-motion wheel hub drive.

With completely new developed climbing systems the company AAT Alber Antriebstechnik GmbH now presented itself on the market. Subsequently, the pushing and braking aid v-max and the add-on drive max-e were successfully introduced to the market. The product portfolio is constantly being expanded with new types of drives and special industry solutions.

On March 31, 2017, AAT Alber Antriebstechnik GmbH was sold to the company REAC AB. REAC AB is a traditional swedish company, which belongs to the Investment AB Latour and has been a successful supplier to the rehabilitation market for many years. AAT remained an independent company within REAC AB.

The company REAC AB becomes MS Group. MS Group is a global provider of products and services in the field of mobility systems to improve the quality of life of disabled and elderly people.

In January 2020, Investment AB Latour, through its subsidiary MS Group, acquires BATEC Mobility S.L. Since then, BATEC (Spain) belongs to MS Group AB with its members REAC AB (Sweden) and AAT Alber Antriebstechnik GmbH (Germany).

AAT Alber Antriebstechnik GmbH takes over the exclusive distribution of the electrical tension devices und handbikes of the company BATEC Mobility S.L. in Germany as of 01.06.2021.

The aim of this takeover is to use existing synergies for the benefit of our dealers and end customers as well as for further development of our product and service range.
