The E6210F is a 21-tonne-class SDLG excavator, a core model developed for harsh working conditions, with a high-strength chassis and a heavy-duty working device. A 123 kW low-speed, fuel-efficient engine (China Phase III) drives a double-pump, constant-power negative-flow hydraulic system with a 0.9 m³ bucket, delivering up to 147.1 kN of digging force, a 6.73 m digging depth, and a 9.94 m digging radius.

Its reinforced lower frame with lengthened crawlers and a widened chassis improves stability and trafficability, while the spacious, sound-insulated cab with shock absorbers keeps operators comfortable. It also accepts attachments such as a crushing hammer for added versatility.
