Conveyor system wheel failure detection and remediation

In a sorting conveyor for transporting objects and unloading objects at one or more unloading stations adjacent the conveyor, said sorting conveyor having a conveyor track and a train of interconnected conveyor carts, at least one of said conveyor carts comprising:

• (a) a frame base for engaging said conveyer track;
• (b) a conveying surface for holding said objects;
• (c) a conveyor support for supporting said conveyor surface above said frame base;
• (d) a carrier having a plurality of wheels and at least one wear guard associated with an axel support for preventing track wear in the event of a wheel failure;
• and
• (e) a track wear prevention system including said wear guard and a height detection module wherein said wear guard inhibits track wear when said module detects a wheel failure.
