SJ-30

The SJ30 is a 3-ton class professional mini excavator designed for users who require stronger digging performance, advanced hydraulic control and reliable operation for demanding construction applications.

Powered by a Yanmar 380F 3-cylinder diesel engine (Stage V), SJ30 provides strong power output, excellent fuel efficiency and long-term durability. Yanmar engines are widely trusted by professional users for their reliability and easy maintenance, making SJ30 a dependable choice for contractors, rental fleets and construction professionals.

SJ30 is equipped with a fully hydraulic load-sensing valve system and variable displacement piston pump, delivering efficient power management and precise hydraulic control. The system automatically adjusts hydraulic flow according to the working load, improving operating smoothness, reducing energy loss and allowing multiple functions to work together efficiently.

The high/low-speed travel piston motors provide strong mobility and adaptability across different job sites. Operators can switch between higher travel speed for transportation and stronger traction for difficult terrain, improving overall working efficiency.

The piston swing motor ensures smoother rotation, better control and improved durability during frequent operation. Combined with the boom swing function, SJ30 offers excellent flexibility when working near buildings, walls or other obstacles, making it suitable for urban construction, landscaping and utility projects.

The extendable undercarriage allows SJ30 to adapt to various working environments. The machine can be narrowed for easier access through limited spaces and expanded to provide greater stability during heavy excavation work.

Equipped with 230×48×82 rubber tracks, SJ30 provides reliable ground contact, reduced surface damage and stable operation on different terrains.

SJ30 combines powerful performance with advanced hydraulic technology, offering the perfect balance between compact size and professional-grade capability.
