Narrative:
On departure, foreign object damage on runway 16R, slc, shredded a tire, which in turn, disabled the hydraulics. System a and B, at different rates and degrees, were damaged. System a was eventually lost and the landing gear was lowered manually. We flew by the tower for a visual inspection. They informed us that they thought the left main gear was 'dragging.' we had a good down and locked indication, but we notified the passenger of the situation and had the flight attendant prepare for a possible collapsed gear on landing. We made an overweight landing on runway 16R in slc. We were able to taxi off and shut down the aircraft for an inspection prior to towing to gate.
