Here's a parts list for the Hatco TRH-60 http://download.partstown.com/is-bin/intershop.static/WFS/Reedy-PartsTown-Site/-/en_US/manuals/HT-TRH_pm.pdf
The baskets are driven by a gear motor and two conveyor chains. If the chains and gears aren't broken, then it is likely the motor. I suppose it is possible the motor isn't getting power. Either way, this doesn't really look like a user-replaceable part, so I'd consider contacting a qualified technician.
I hope this helps!
