Excavator 1452
The excavator 1452 with the type designation SRs 1200 is a bucket wheel excavator that was manufactured in 1961 by VEB Schwermaschinenbau Lauchhammerwerk for lignite mining and was in use until 2001.
After it was decommissioned, the bucket wheel excavator remained in the former Berzdorf opencast mine near Görlitz (today Berzdorfer See ) and has since been preserved as a museum by the Berzdorf - Oberlausitz Mining Association . Due to its importance in terms of local history and technology, it was also included in the official list of cultural monuments of the Free State of Saxony.
history
In 1961 the bucket wheel excavator was built in the Phoenix opencast mine south of Leipzig and used for extraction until it was closed in 1968. In 1970 it was dismantled into individual parts and transported to the Berzdorf opencast mine. There he mined lignite until the open pit mining was closed in 1997. The bucket wheel excavator was then used for recultivation until 2001. The original plan was to scrap the excavator after it was decommissioned. However, the Berzdorf - Oberlausitz mining contemporary witness association advocated the preservation of the excavator and made it accessible to visitors.
Technical specifications
The bucket wheel excavator was manned by at least 3 men, had an installed power of 1650 kW and was supplied with a 6 kV power cable.
The bucket wheel excavator is 33.5 meters high, 75 meters long and 47.85 meters wide including the loading arm. The wheel boom and the loading boom each measure 29 meters in length and the feed extends to 12 meters.
The 6-part crawler track with a track width of 12 meters and a maximum travel speed of 6 meters per minute carries the total weight of 1940 tons and is 23 meters wide and 25 meters long. It creates a ground pressure of 1.3 kilograms per square centimeter. The excavator needs a radius of 50 meters for turning.
With 8 shovels of 1.2 cubic meters each and 52 dumps per minute (so-called dumping number), the excavator achieves a theoretical excavation capacity of 3744 cubic meters per hour. The bucket wheel diameter is 8.6 meters and the cutting speed is 2.84 meters per second.
The construction of the wheel arm enables a removal height of up to 24 meters and a removal depth of up to 4 meters as well as a block width of 30 meters. The wheel arm can be swiveled 120 degrees in both directions at a speed of 6 meters per minute.
At a belt speed of 3.3 meters per second, the excavated material is transported to the loading boom on the 1.88 meter wide conveyor belt. This can be swiveled by 75 degrees in both directions.
