It's still trains the whole posterior chain, but in the context of bodybuilding these are useful for back and traps. Note that you'll pull a fair bit more than on your deadlifts, due to the shorter distance traveled, and higher angle of the back at the start of the movement (closer centre of gravity = more potential output).
I'll second cleans, rows, conventional deads, farmers walks, etc. Basically, any exercise where you're holding heavy weight will hit your traps hard.
Also, as a minor sidenote, your traps will get a little extra stimulation as a stabalizer in pushing movements like bench and military press.
If, after all these compound/heavy hold exercises, your traps still aren't responding as much as you'd like, then incorporate some isolation.
