Mining Excavator

SDSG KWC mining excavators are crawler diggers built specifically for underground metal mines, tunnels and confined headings. The range covers the 1.92-ton KWC2.2/0.029L micro excavator — powered by a Kubota D1105 engine and compact enough for the narrowest drifts — and the 5.85-ton KWC5.5/0.22L, driven by a China IV Yanmar 4TNV94L with 0.22 m³ bucket capacity. Both run a mining-spec reinforced chassis with roughly 10% thicker steel plate and a lower centre of gravity for stability on uneven mine floors. Plunger-pump hydraulics and a backhoe front give strong digging force for mucking, trenching and rock work; breaker piping is standard, with a quick coupler, rotary drill and dozer blade available.
