Get A QuoteOverview
The SY155W is a 13.7 t wheeled excavator designed to travel between job sites under its own power, eliminating low-loader logistics for road and utility contractors. It is the productive choice for crews moving frequently across urban networks.
A 120 kW Isuzu 4HK1X engine drives a 0.65 m³ bucket with 102.3 kN bucket digging force and 75 kN arm digging force. Electro-hydraulic control and DOMCS dynamic optimization match power to demand, while dual-circuit braking, cruise and travel-shift protection keep road travel safe.
A Tier 4 Final / Stage V variant (15 t, 115 kW, 0.22–0.7 m³) is offered for stricter markets, and SANY's dealer network across 180+ countries supports parts, training and warranty. Request a price quote for your emission requirement.
