Heinrich Ranafier

from Wikipedia, the free encyclopedia

Heinrich Ranafier (* 17th June 1846 in Hamburg-Altona , † 25. November 1930 in Oldenburg ) was a German engineer of the railways and Secret Oberbaurat .

Life

Ranafier, who grew up in Altona, at the time an independent town in the entire Danish state , showed a keen interest in mechanical engineering from an early age . Even when he was still at school, he practically worked in a machine factory in his hometown. He then attended the Protechnikum Hamburg for a year and then studied mechanical engineering in Hanover from 1866 to 1870 . There he joined the Corps Saxonia Hannover . Ranafier then worked briefly as a draftsman at what was then Strousbergschen Maschinenfabrik, the predecessor of Hannoversche Maschinenbau AG ( Hanomag ).

On November 4, 1870 Ranafier entered the higher technical service of the Grand Ducal Oldenburg Railway (GOE) as a machine engineer .

In 1873 he was first assistant to the foreman and in 1876 he became a foreman himself. In 1893 he was promoted to the building council and since 1899 he was also a member of the railway management as a mechanical engineering member . In 1901 he was promoted to the senior building officer and in 1912 to the secret senior building officer. Ranafier's management was also responsible for the procurement and maintenance of the railway company's extensive passenger and freight wagons as well as the workshop. In addition to his work in committees, he also supervised the ferries and steamships of the GOE, in some cases personally, and had thus acquired extensive expertise in shipbuilding, so that he was often called in as a senior consultant and expert. After 46 years of service, Ranafier retired on November 1, 1916. One of the last GOE locomotives that he significantly influenced was the Oldenburg S 10 , one of the few prairie locomotives in German railway history, delivered in three copies by Hanomag in 1916 .

Ranafier's name is closely linked to the history of the Oldenburg state railway. In particular, it had a major impact on locomotive construction. Furthermore, several locomotive-specific inventions are named after him. From 1909 he introduced the Lentz valve control to the newly procured locomotives , on the development of which he had worked and which was awarded the gold medal at the Brussels World Exhibition in 1910 .

family

Ranafier was born with Johanne Kahle (1853–1938) married. Of the couple's four children, Max Ranafier (1881–1955) also became a railway engineer, most recently Ministerialrat and Vice President of the Wroclaw Railway Directorate . In 1928 he married the Oldenburg artist Hedwig Ranafier-Bulling (1882–1961).
