Maintenance of Bucket Elevator
 

1. CHECK BELT FOR TEARS, CUTS, ETC.
Sudden signs of unusual damage call for immediate action.
 
2. CHECK CUPS FOR LOOSE OR MISSING BOLTS
A loose dangling cup is the necessary lever to start a busted belt rip.
 
3. REPLACE BELT CUPS
Cups with a pronounced forward bend hold the belt in a vertical arc, which is a contradiction of forces. When the belt is bent in a horizontal arc around the pulleys, this will cause lengthwise cracks to appear at the bolt holes.

4. CHECK BELT TENSION
This is a possible source of drive slippage and excessive wear. Belts running loose in a leg are put to severe flex due to lack of full contact with the boot pulley. A loose belt may swing causing the cups to catch and tear the belt.

5. CHECK ALIGNMENT
Belts not running true due to out-of-plumb pulleys, idlers or casing cause edge wear and pave the way for costly accidents. 

6. CHECK SLIPPAGE ON DRIVE PULLEYS
Proper lagging of pulleys can increase efficiency and belt life appreciably.

7. CHECK BUCKET ELEVATORS FOR UNEVEN LOADING
This can cause the belt to crawl across the head pulley and cause edge wear or break the belt fabric.

8. CHECK BOOT FOR WATER
A belt allowed to sit in water will rot and tear very easily.

9. CHECK DISCHARGE THROAT
The throat to the down leg should be closed as much as possible with a piece of rubber belting adjusted close to the cups. This will prevent back legging.
