In November last year, the 200000 units of Sany medium-sized excavators were taken offline, and the new 2025 model of medium-sized excavators was released simultaneously. Sany medium-sized excavators embarked on a new journey with a brand new upgrade, and its strength and determination are believed to be firmly verified in the market soon.
