Brakeman (trailer)

A brakeman is the name given to a person who was able to operate the brakes of a trailer behind a motor vehicle independently of the driver .

The first trailers behind trucks were not equipped with brakes. In 1908, when truck subsidies began , there was also a regulation that a trailer with a 2 t payload should be attached behind the truck. The heavy trailer was usually equipped with a block brake. The brakes were operated by a brakeman, which was compulsory until 1913 and could be placed on the trailer. After the First World War , trucks with several trailers were put into operation again; this gave the brakeman his authorization. So that the brakeman was protected from the weather, he sat in a "brakeman's house".

With the revision of the Ordinance on Motor Vehicle Traffic of December 5, 1925, the extra-long trains disappeared - apart from exceptions requiring approval - as a maximum of one trailer was allowed. However, the regulation continued to mention a brakeman who had to ride on the trailer if the trailer's brake could not be operated by the driver. In practice there was no exception, as the Knorr-Bremse was introduced in 1923. Even with the introduction of the StVZO in 1937, the brakes were left, but Section 41 (6) limited the brakes for trailers up to a maximum speed of 20 km / h:

"If the brakes on these trailers can neither be operated by the driver of the towing vehicle nor work automatically, they must be operated by brakes who must have a clear view of the road."

- § 41 (6) StVZO of November 13, 1937

This regulation was valid until January 1st, 1961 for newly registered trailers with a top speed of 20 km / h.
