The 2023 SANY SY155U is a used mid-size hydraulic excavator built for general earthmoving, trenching, grading, and site development work. With an operating weight of 35,274 pounds, it fits the class of machines commonly used on residential subdivisions, commercial building pads, utility installations, and road and bridge projects where a compact-radius footprint is useful in confined work areas.

This excavator offers a practical balance of digging power and transportability. A maximum dig depth of 17 feet 11 inches and a ground level reach of 27 feet 4 inches allow crews to complete deep utility trenches, footings, and basement excavations without repositioning frequently, while 23,155 pounds of bucket breakout force supports work in compacted soils and mixed material. Its weight class typically allows transport on standard equipment trailers, reducing mobilization time between job sites.

Key specifications include an Isuzu FT4-4JJ1X diesel engine producing 103.9 horsepower, a 15-foot 1-inch boom, an 8-foot 2-inch stick, and 24-inch track shoes for stability and flotation on soft ground. The reduced tail swing configuration helps operators work near curbs, structures, and traffic.

Excavation contractors, underground utility crews, site development companies, landscapers, municipalities, pipeline installers, and rental fleets commonly use SANY excavators in this size class for daily production digging and general construction tasks.
