Frequently Asked Questions About Excavators
What is the difference between a mini excavator and a medium excavator?
Mini excavators typically weigh under 6 tonnes and are ideal for confined spaces, residential projects, and light earthmoving. Medium excavators weigh between 6 and 20 tonnes and are suited for larger construction sites, trenching, and commercial projects.
What can an excavator be used for?
Excavators are used for digging foundations, trenching, demolition, grading, landscaping, mining, and material handling. With the right attachments, they can also be used for rock breaking, crushing, and forestry work.

Does MCM sell electric excavators?
Yes, MCM Group offers electric excavator models that provide zero-emission operation, lower noise levels, and reduced running costs. These are ideal for indoor demolition, urban projects, and environmentally sensitive sites.
In South Africa, excavator selection depends primarily on the digging depth, bucket capacity and transport logistics required for the project. Mini excavators (1—5 tonne) are transported on a small trailer, access residential sites through standard gates and dig typical service trenches to 2—3 m depth. Medium excavators (8—20 tonne) are the standard choice for bulk earthworks, dam walls, road cuttings and commercial foundations. Large excavators (20+ tonne) are used in open-cast mining, quarrying and major civil projects requiring high production rates.
Hydraulic system performance — specifically flow rate and working pressure — determines which attachments an excavator can run. Standard hydraulic circuits support buckets, thumbs and quick-couplers. Auxiliary circuits (single or double acting) are required for hydraulic breakers, drum cutters, bucket crushers, screening buckets and sorting grapples. Confirm auxiliary circuit specification before purchasing an attachment.
