PROBLEM TO BE SOLVED: To efficiently perform excavation to its underground part and lifting of excavation sediment from the inside of a building. SOLUTION: This excavating/lifting device has a lifting mechanism (a chain block 9) for lifting a frame by taking reaction from a peripheral skeleton by liftably arranging the frame 6 inside an opening part 2 formed on a floor surface of the work floor, and a locking mechanism (a pin 12) for locking the frame on the peripheral skeleton in both a work position and a storage position inside of the opening part. A cram shell 5 is mounted inside the frame, and a work stage 20 is arranged in a lower part in the frame. The opening part capable of passing a bucket 16 of the cram shell and a carrying-out mechanism (a belt conveyor 23) for carrying out the excavation sediment to the side by receiving the excavation sediment from the bucket, are arranged there, An awning deck 25 being a floor surface of the work floor is arranged in a top part of the frame.
