History
Since 1745 JDN has been manufacturing lifting equipment, now in the seventh generation.
In 1745 our ancestor Johann Diederich Neuhaus was found worthy to be listed as an "industrialist" in the "Sprockhoevelschen Factory Register" and to be accepted in a kind of "Commercial Co-Operative". We have been manufacturing "JDN Hoists" ever since and are now in the seventh generation.
At first we mainly produced jacks with wooden shanks and no carter wanted to travel without these jacks because of the terrible road conditions and the continuous wheel and axle damages.
We still manufacture jacks today but many basic principles have changed. The "Significant Date" for this was in 1952 when we had the idea to put a pneumatic motor to a so far manually operated pulley block.
Main customer of our pneumatic hoists was the coal mining industry where a product has to be robust and reliable if it wants to prove itself.
Towards the end of the 60`s we developed special pneumatic hoists for industrial applications: the JDN Air Hoists "PROFI" series. They can be used wherever there is a danger of explosion or where loads have to be moved very sensitively. For the ship building industry we developed a "PROFI" with a carrying capacity of 100 t.
As the first company in the material handling industry we received the Certificate for Quality Assurance in 1991. In the same year we widened our delivery programme to become a universal supplier of complete crane installations.
In 1998 we launched the compact air hoist of the mini series.
Emma Neuhaus
(21.9.1859 – 29.1.1932)
At the age of 57 Louis Neuhaus died and his wife Emma who outlived him by 27 years took over the whole responsibility for the family, house and business. Without her dedication the age-old tradition could have easily come to an end.
Emma Neuhaus took overall responsibility for running the business although in the smithy it was very difficult to substitute her husband. She had to work with an unskilled labour force but the financial accounts for those times showed a steady continuity. For special equipment she was assisted by the foreman Wilhelm Müller who had learned his trade in the smithy and who completed this special work in the evening when the rest of the workforce had finished for the day. In 1907 both married.
In 1922 she handed over the whole property to her youngest son Max Neuhaus with the consent of her second husband and her still alive children.
