The equipment that is best for the job depends on the characteristics of your mine site. Hydraulic mining shoves, electric rope shovels and large wheel loaders all have their advantages. But only one of these machines — the large wheel loader — can serve double duty, working as both a loader and a support machine for other loading tools on site.
Combining nearly 50 years of Siemens AC mining shovel drive experience with IGBT (Insulated Gate Bipolar Transistor) technology guarantees the most reliable shovel solution with higher productivity and lower operating costs. Due to the mining shovels'' AC drives, they are able to operate faster than their counterparts with DC drives.

The shovel is offline % of the time and it propels to a new digging position % of the time. Siemens builds drive systems for electric shovels. The cycle time for an electric shovel differs slightly from a hydraulic excavator. For an electric shovel with a 70º swing radius, the cycle time averages seconds, according to Koellner.
Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping.
