Clam shell is a machine used for Excavating. Clam shell is a bucket or grapple (as on a dredge) having two hinged jaws.

Hoe can be used to excavate relatively stiffer earth from a depth below the standing level of the equipment. 

Drag line can be used to collect the loose material from a much larger depths.

Power shovel can be used to excavate the loose earth material effectively and can be used in undulating grounds because it has a crawler mounting.
