Product Description
Built for serious work, this 2021 Sany SY125C delivers proven 12-ton excavator performance at a fraction of new equipment cost. Sourced directly from Guangdong, China, this backhoe excavator pairs a reliable Isuzu 4JJ1 water-cooled diesel engine (73 kW / 365 N·m torque) with a robust hydraulic system — giving contractors and fleet operators a high-output machine without the capital burden of buying new.
Smart buyers understand that a well-maintained used excavator holds its productive value. With 90.6 kN bucket digging force, a 5,190 mm maximum digging depth, and 70% climbing ability, this SY125C handles demanding earthmoving, trenching, and site preparation tasks with confidence. Its 240L fuel tank and efficient 3L displacement engine keep operating costs low across long shifts.
