The company for mining equipment Aue (BBA) was a mining accessories manufacturer of the Wismut AG / SDAG Wismut in Aue in Saxony. It goes back to the Hiltmann & Lorenz company and was liquidated in 1992. The buildings are re-used.
history
Forerunner company: Hiltmann & Lorenz
The company Hiltmann & Lorenz ( HiLo ) in 1879 by two former employees of the company Erdmann Kircheis that Schlosser founded Gustav Hiltmann and Bernhard Lorenz. The production profile included the manufacture of machines for sheet metal, metal and wood processing. On April 14, 1911, the company was converted into a stock corporation and registered as such on June 14, 1911. In September 1928 Hiltmann and Lorenz bought the branch of Zwickauer Maschinenfabrik AG (formerly Gustav Toelle sheet metal processing machines ) in Niederschlema. On January 20, 1932, the company had to stop making payments due to economic difficulties and applied for a court settlement procedure . This procedure was confirmed on March 17, 1932 and the company was considered to be restructured.
After the end of the war, in the summer of 1945, the SMAD confiscated the plant and ordered the dismantling of the facilities. The dismantling for reparations to the Soviet Union began on August 5, 1945. By March 1946, 98 percent of all facilities in both parts of the company had been dismantled and removed. During the dismantling, however, operations were resumed with the repair of railway wagons. As a result, the reconstruction of the plants and production based on the former product range began. The first orders have already been carried out for Wismut AG . Pressen- und Scherenbau Henry Pels in Erfurt took over the already started production. On January 1, 1949, the Hiltman & Lorenz AG company was liquidated and transferred to the state of Saxony in trust.
Metallist plant / 512 plant
The two parts of HiLo were incorporated into Wismut AG on June 1, 1949 as separate operations with the names AG Wismut Werk Metallist (Aue) and AG Wismut Werk Strehla (Niederschlema). On February 1, 1950, the name of the Auer plant was changed to AG Wismut plant 512 .
In order to standardize the administration of the Wismut supplier companies as well as the mechanical companies, the object 34 was built in 1948, to which the following companies were gradually subordinated:
- Plant 501 in Hohenstein-Ernstthal , manufacture and repair of centrifugal pumps
- Plant 505 in Aue, manufacture and repair of hammer drills and pick hammers
- Plant 512 in Aue, manufacture and repair of mining machines
- Plant 519 in Schlema, production of drill rods for geological drilling
- Plant 527 in Grünhain , production of electric motors
- Plant 536 in Cainsdorf , steel and mechanical engineering
- Fackel foundry in Zwickau , manufacture of gray cast iron products
- Assembly office in Cainsdorf, assembly of equipment in the mining and processing plants.
On February 1, 1951, plants 501, 505, 519 and 527 were dissolved and integrated into plant 512. The production of the electric motors and drill rods remained as independent departments in Schlema and Grünhain. With the dissolution of Object 34 on December 31, 1960, Plant 512 became economically independent.
Operation for mining equipment Aue (BBA)
Since the early 1960s, the plant has been producing 512 mining equipment not only for companies in the GDR, but also for export. Therefore, on January 1, 1968, the company was named SDAG Wismut Operation for Mining Equipment Aue (BBA).
The company also participated in activities in the city, so members of the mining company 09 and the BBA had reconstructed and expanded a former hut house in Berg Freiheit in 1973 , which corresponded to a value of around 700,000 marks and a contribution for the upcoming 800-year Celebration of the city of Aue. The town museum developed from this building after the fall of the Wall . In 1974 a sheltered workshop with 45 workplaces for former miners was set up in the BBA .
A notable element from the BBA were the lighting cubes installed on the corner pillars of the station bridge in 1977 , which were dismantled after 1990.
The production capacity of the company had to be constantly expanded and technically improved in accordance with demand. In addition, the management also took care of the improvement of the working and living conditions of the working people - at the beginning of the 1980s a new multi-purpose building was handed over to its intended use on the factory premises.
After German reunification
The German reunification led, among other things, to the dissolution of the bismuth in its previous structures. On January 1, 1992, the German Manufacturing and Plant Construction Company (DFA) was founded, which combined all of Wismut's ancillary operations. Due to the decline in sales of mining equipment, due to the sudden cessation of almost all underground mining in the GDR, and the lack of an investor, the BBA Aue was liquidated in 1992.
- School center
The city administration of Aue had the buildings renovated inside and out. Then, in 1993, the remaining complex became the location for the new vocational training center for technology, which bears the name Erdmann Kircheis .
Products
Overview
The BBA manufactured mining equipment and equipment that was required in the uranium ore mining of SDAG Wismut. These included mine fans , rotary hammers , Bohrstützen , Drilling , bunker loader , Front loader , LHD , Grubenloks, electric motors and switchgear and control systems.
An important area within the company was the repair department, in which welders, locksmiths, lathe operators and other skilled workers ensured that the mining equipment of the Auer pits was always ready for action.
Rotary hammer BHS26S (rotary hammer, column-guided, 26 kg, flushing head)
Drill support BS 62/77, with rotary hammer
Dismantling drill rig BWA 3 (drill rig, dismantling)
Fahrlader ULE 2 (universal loader, electric drive)
Fahrlader UL 2 (universal loader with diesel drive)
Mine locomotives
Production began in 1949 with the Metallist locomotive . As a result, battery locomotives and catenary locomotives were built in a wide variety of variants. The different types were always tailored to the requirements of the mining operations. Not every modified series was given its own name.
The different versions identified by letters and numbers are:
- BBA Metallist ( battery locomotive )
- B 345 (battery locomotive) for export to the CSSR
- B 346 (battery locomotive), export CSSR
- BBA B 360 (battery locomotive)
- BBA B 660 (tandem battery locomotive)
- BBA EL 61 (tandem battery locomotive, for BB Drosen also in 750 mm gauge)
- BBA EL 71 (tandem battery locomotive)
- BBA EL 79 (tandem battery locomotive)
- BBA EL 30 (catenary locomotive)
- BBA EL 30 T (tandem catenary locomotive)
- BBA FA 860 (combined tandem overhead line battery locomotive)
From 1952 until production was discontinued in 1991, around 2700 locomotives were built. These were not only used in the mining operations of the Wismut, but also delivered to other mining and industrial operations in the GDR, as well as exported.

Overhead loader
PML series
To mechanize loading work, the first PML 3 overhead loader was built in 1949 according to Soviet design drawings. The use of these technically not fully developed machines was difficult and had to be encouraged with the payment of bonuses. As a result, the types PML 4, PML 5, PML 17 and PML 17M were developed due to constant improvements. From 1954 the new PLM 63 loader was built. Between 1950 and 1989, 2200 loaders were built.
The loader did not yet have a step, so the operator had to run next to it. The superstructure still had to be swiveled by hand.
PPN1 / LWS110 / LWS 160
The PPN1 imported from the Soviet Union was an improvement. This had a running board and the superstructure could be pivoted mechanically. The LWS 160 and LWS 160/2 loaders, which replaced the PPN1, were built at the BBA from 1978. 500 loaders were built between 1978 and 1989.
Bunker loader
When the transition to rail-less operation in driveways, other loading machines were necessary. The compressed air-powered bunker loader LB 125/1000 was built from 1969. This was probably modeled after an Atlas Copco Cavo 310 imported from Sweden. 1200 pieces of this type were built between 1969 and 1989.
80 of the larger LB 500/2000 were built between 1974 and 1989. These loaders were not only used by the Wismut, but also in other mining operations.
Wheel loader
With the decreasing demand for mining machines, the development of a wheel loader for Germany and export to the Comecon countries began in 1986. An annual requirement of 400 wheel loaders was assumed. Production started in the second half of 1990. By the end of production in the BBA, around 50 machines of the types RL 50, RL 100 and RL 200 had been built and sold under the name WISCON. The Belgian company Renders Trailers NV founded Renders International GmbH in 1992 in a joint venture. The company was based on the premises of the Wismut motor vehicle repair company, formerly Wanderer-Werke-Chemnitz in Chemnitz-Siegmar. Here the wheel loaders continued to be built under the name Renders until 2000.
