Product Description
Engineered with a 73kW Isuzu 4JJ1-XDJAG-01-C3 diesel engine delivering 365 N·m maximum torque, this 2020 Sany SY155C mid-size excavator combines proven hydraulic architecture with field-tested reliability. Operating at 15 tons working weight, the machine generates 92.7kN bucket digging force and 66.13kN arm digging force—performance metrics that translate directly to cycle time efficiency in loading, trenching, and demolition applications.
Hydraulic systems feature a 150L tank capacity supporting 12 rpm swing speed and precise multi-function control. The undercarriage employs 500mm triple-grouser track shoes across 44 plates per side, distributing 14,100kg across a 43kPa ground pressure footprint—ideal for soft terrain stability. A 0.55m³ backhoe bucket handles high-volume material movement, while the 70% gradeability and dual-speed travel system (5.5/3.5 km/h) ensure productivity across varied jobsite topography.
Currently located in Maoming, Guangdong, this Chinese-manufactured unit represents Sany's commitment to durable componentry and straightforward serviceability in the 15-ton excavator segment.
