Wherever huge amounts of overburden and earth have to be extracted and moved efficiently and cost-effectively in order to get at deeper raw material layers large bucket wheel excavators are used. In lignite mining they achieve capacities of up to 240,000 m³ (bank) per day, digging heights of as much as 100 m and service weights of 13,500 tons.
Depending on the mine plan, thyssenkrupp bucket wheel excavators are supplied with a connecting conveyor bridge and loading unit or as a single unit with discharge boom.
For lower volumes or specialized jobs thyssenkrupp offers compact bucket wheel excavators. Typical features of all compact bucket wheel excavators are their two-crawler travel mechanism, a so-called C frame construction and a counterweight below the discharge boom.
