Second-hand Sany excavators are classified by tonnage as follows:
– **Mini-type** (e.g., SY16, about 1.8 tons), suitable for indoor and narrow-space operations.
– **Small-type** (e.g., SY55, approximately 5.8 tons), used in municipal projects and agriculture.
– **Medium-type** (e.g., SY215, around 21 tons), suitable for conventional earthwork at construction sites.
– **Large-type** (e.g., SY485, about 49 tons), with strong power for mines and large-scale projects.

Most are diesel-powered, while some models feature electric technology for high efficiency and energy conservation. When purchasing, inspect the engine condition, hydraulic system tightness, and track wear.
