2. _By Span:_ Short-span (up to 10 meters), medium-span (10-20 meters), long-span (above 20 meters)
3. _By Lift Height:_ Low-lift (up to 10 meters), medium-lift (10-20 meters), high-lift (above 20 meters)
_Types:_
1. _Single-Girder Crane:_ One girder supports the trolley and hoist.
2. _Double-Girder Crane:_ Two girders support the trolley and hoist.
3. _Semi-Gantry Crane:_ A combination of a girder and a gantry.
4. _Gantry Crane:_ A crane with two legs and a bridge.
_Applications:_
1. _Manufacturing:_ Assembly lines, material handling.
