            Tie tongs
            Railway workers can easily move railroad ties or sleepers with these 
carrying tongs. The jaws are adapted to the load as there are carrying 
tongs for road curbs, crucibles, railroad tracks, etc. The arms move away 
from each other so that they automatically clamp when the tool is lifted. 
These tongs are one of the few tongs that are handled by two people. See 
also the two handled lifting tongs of a lumberman. [MOT]
