Classification of crane reducers/gearbox

Crane reducers/gearbox are equipment used for deceleration and are widely used in docks, construction, steel mills, and other construction industries that require lifting heavy objects.
According to their lifting standards, they are generally divided into four categories: super large, large, medium, and small.
1. Super large crane reducer
Mainly used in construction, docks and steel industry, generally with a load of more than 150T.
2. Large crane gearbox
Mainly used in steel industry, construction machinery, etc., generally with a load of 50-150T.
3. Medium crane reducer
Mainly used in factory buildings and small construction machinery, with a load of 5-50T.
4. Small crane reducer
Mainly used in small factory buildings, with a load of less than 5T, commonly known as electric hoist.
