名词 n.
  1. Any of several very large vehicles used for lifting, especially in the process of mining: basically an excavator which drags its bucket to fill it.
    — In mining with a dragline excavator, the upper half to two-thirds of the alluvium contains too little of the previous metals to warrant washing; hence this part of the overburden is lifted by the excavator and dumped to one side of the cut.
