Chain bucket excavators are the direct descendants of the dredges employed from the 17th century in the Netherlands to deepen shipping channels and harbour basins. At the beginning of the 19th century the first steam dredges were built in the USA and the UK. Steam dredges were widely employed during construction of the Suez and Panama canals. Since the middle of the 19th century steam powered chain bucket excavators were developed by French designers for digging dry sediments like sand, gravel or clay above the ground water level.
The use of chain bucket excavators with lignite opencast mining in Germany started at the begin of the 20th century. While the early models were rigid, steam powered and invariably running on rails. Nowadys opencast mining industry employs a variety of different types, which are invariably electrically powered. While the larger types are still running on rails, the smaller ones are moving on crawlers. The bucket chain is motile and may be adjusted for cutting downwards, horizontally or upwards. All major components, lower works with the crawlers, middle works with the loading arm as well as upper works with the bucket chain can be swiveled independently by 360 degrees around the central verical axis. Ihis feature increases versatility considerably in comparison to older models.
According to the nomenclature used in East Germany to classify opencast mining equipment this type was designated ERs500. E was standing for chain bucket, R for crawlers and s for swiveling upper works. 500 is the volume in litres of each bucket.
The ERs500 is one of the smaller types mainly used for harvesting residual amounts of lignite or pockets of byproducts like quartz sand or gravel, which cannot be selectively harvested by bigger excavators.
The development of chain bucket excavators has come to an end as they are gradually replaced by bucket wheel excavators, which are even more versatile, allowing even more selective excavation of lignite and overburden.
The model is built as an industry asset, which can load lignite into enabled railcars. The animation of the bucket chain is controlled by script.
