Product Description
Engineered with Volvo's renowned D4E four-cylinder engine, this 2017 EC170D delivers 90-91 kW at 2200 rpm with 495 N·m maximum torque, ensuring consistent performance across demanding excavation tasks. Operating in the 17-ton class, this machine features dual variable displacement axial piston pumps generating 2 x 150 L/min flow through a robust 34.3 MPa working hydraulic circuit. Bucket digging force reaches 116.7 kN while arm digging force peaks at 98.2 kN, supported by a maximum tractive force of 145 kN for superior material handling capability.
Built to joint venture/import standards, the EC170D offers exceptional reach specifications: maximum digging radius of 9344 mm, digging depth to 6440 mm, and dumping height of 6539 mm. The hydraulic system maintains precise control through dedicated circuits—34.3 MPa for working functions, 26.5 MPa for swing, and 3.9 MPa for pilot operations. With 70% gradeability and dual-speed travel (3.1/5.6 km/h), this Jiangsu-located excavator combines Swedish engineering precision with field-proven reliability for contractors requiring technical superiority in medium-duty applications.
