Which of the following is NOT one of the three basic crane types?

Explanation:
Three common crane types used in basic training are mobile cranes, tower cranes, and overhead cranes. A gantry crane isn’t counted among those three because it’s a variation of an overhead crane that is supported by legs and travels on rails on the ground, rather than being mounted to the building’s structure or moving a bridge on overhead runways. In practice, gantry cranes perform similar lifting work to overhead cranes but use a different support system, so when the basic trio is listed, a gantry crane is distinguished from that group. Therefore, the option describing gantry cranes is the one that isn’t among the three basic crane types in this context.
