What are common problems with SANY excavators?

Written by Editorial Team | Last Updated: August 2026

SANY excavators are heavy industrial earthmoving machines built for rugged construction sites, but operators occasionally face mechanical and electrical difficulties. Common problems include hydraulic system pressure drops, sluggish multi-function bucket movements, and hydraulic fluid overheating caused by contaminated oil or worn-out pump components. Electrical glitches involving faulty wiring harnesses, dashboard monitor errors, and sensor calibration issues are also reported. Undercarriage wear, track tension loss from debris accumulation, and premature fuel injector clogs due to poor fuel quality require consistent field inspections, lubrication, and timely component servicing.
