The NT25 is a 2.5-tonne crawler excavator from the NT series, powered by a Changcai 390 engine rated at 20 kW. Bucket capacity is 0.07 m³, maximum digging depth 2752 mm and maximum digging height 3427 mm — with a 4519 mm maximum digging radius that is long for its weight class.
A 3.4 km/h travel speed, 1900 mm track length and 35% gradeability make site-to-site movement efficient. At 3966 mm long, 1350 mm wide and 2280 mm high, it loads onto a standard small flatbed without dismantling. The hydraulic system uses a gear pump with Dana travel and swing motors.
Rubber tracks, a sun canopy and a dozer blade (281 mm maximum digging depth, 214 mm maximum lifting height) are fitted as standard. Optional equipment includes engine, cabin, tracks, retractable undercarriage, air conditioner, two-speed motor and hydraulic quick coupler.
