The Otto Kaiser Maschinenfabrik KG was an early German mixing plant and tower crane manufacturer from St. Ingbert , with production facilities in St. Ingbert and 1938-1974 also in Lahnstein .

history

The company, which was founded in 1846 - 15 years after St. Ingbert became a town - was initially called "Voss, Lamarche and Co." and is considered the first machine factory in the town, which had 5000 inhabitants at the time. Three years later, after a change of shareholders, the company changed its name to “Weyland, Lamarche and Co.”, and from 1866 to “Weyland, Meuth and Co.”. In addition to machines of various kinds, pumps, cast-iron grave crosses, transmissions , conveyors, steam boilers and steam engines were produced. After another change of ownership in 1899, the company was called "Rheinpfälzische Eisenindustrie GmbH St. Ingbert" and, according to the commercial register, was engaged in the production of iron structures of all kinds as well as ironwork, grilles and building fittings.

Otto Kaiser joined the company as an engineer in 1906 and invested all of his assets. Two years later, the threat of bankruptcy caused Kaiser's brother-in-law, the legal advisor Richard Schlaudecker, to transfer the company together with Kaiser on October 6, 1908. Around 40 employees now worked for the "Rheinpfälzische Eisenindustrie, owner Kaiser and Schlaudecker, St. Ingbert". After the deaths of both Schlaudecker and his widow, the company was renamed "Maschinenfabrik Otto Kaiser" on February 22, 1927, and it was to last for 50 years.

The patent for the free-fall mixer , registered with the Imperial Patent Office in 1908 , in which the blades in a rotating drum are optimally arranged to lift the mix and drop it again, brought about the hoped-for boom in the company. The building boom that began in the 1930s - especially in the construction of roads and bunkers - enabled the products to be used throughout the German Empire. From 1940, the first European arrived transport mixer with an initial capacity of 3.5 cubic meters on the market that could deliver the finished mix across the street at each construction site for the construction and civil engineering a revolutionary development. The 5.5 cubic meter model was added in the early 1960s and the 10 cubic meter model from around 1980.

From 1910 tower cranes with bending beam booms on portal undercarriages were developed and brought onto the market from 1912 with great success. These devices are among the first constructions to be described as construction or tower cranes. From around 1952 Kaiser also developed and produced bottom-slewing tower cranes with luffing jibs, which were widely used. At the beginning of the 1960s, the Kaiser company achieved another pioneering design achievement with the development of a top-slewing tower crane with an articulated trolley jib . The first model was the HBK 50.1 . Cranes of this type were very successful in the construction industry until the 1980s. Well-known construction companies such as Philipp Holzmann , Beton- und Monierbau , Hochtief etc. use these cranes. Further crane types were developed on the basis of this crane system, followed by the HBK 70.1 , HBK 90.1 , HBK 100.1 , HBK 130.1 , HBK 150.1 and the largest in the crane program - the HBK 160.1 . In the 1970s, cranes with a rigid trolley jib were also developed, the HBS series with the upper tower offset backwards by about one tower width. Climbing of the HBK and HBS series was also patented, the tower parts were placed on the tower by means of their own boom through the slewing ring. The crane could then pull itself up on the raised tower. When the articulated jib patent expired, cranes of this type were also built by Peiner (SKK series) and Liebherr (HC-K series).

OTTO KAISER went bankrupt in 1984 and crane construction was then continued by ELBA from Ettlingen as ELBA-KAISER. Due to a lack of further development and outdated technology (unchanged since the 1970s), crane construction was discontinued in 1994. The almost 100 patents filed over the years could not stop the end.
