The Siebenhaar Company was founded in 1965 by Ted Siebenhaar, B.Sc.(Eng.). Siebenhaar was a pioneer in the field of planetary gears built in winches.
In terms of technology, Siebenhaar was a leader in the fields of winches, swingers and slew drives. However, it was not until 1986 that the market began an upward trend.

Siebenhaar-Antriebstechnik was sold in 1986 to the Krupp Group. Three years later, Dr. Jamshid Yektai acquired the Siebenhaar Company from the Krupp Group. The new development of the Siebenhaar Company as an independent family business began in 1990 with approximately 30 employees and annual revenues of five million German marks.

Within just 15 years - from 1990 to 2005, the Siebenhaar Company has developed into the leading designer and manufacturer of:

- Winches
- Free fall winches
- Swingers, slew drives
- also shiftable wheel drives
- Custom made specialty gears
