10. Belting, Splicing and Buckets
24 PNEG-681 Series II Bucket Elevator
Buckets
Buckets are attached to belting using elevator bolts pushed through the belting back side, through the
elevator bucket, a flat (fender) washer, a lock washer and a nut.
1. Secure bucket by tightening nut to slightly indent belt back with bolt head.
2. Remember to leave buckets off near the splice area, if installing buckets prior to belt installation.
(See Figure 10A on Page 23.)
Torque requirements are as follows:
• 50" pounds for 1/4" bolts
• 96" pounds for 5/16" bolts
• 180" pounds for 3/8" bolts
3. ALWAYS re-check bolts for correct torque after initial start-up and periodically thereafter.
Belt Slack Removal
Remove any slack in belt after splice connection by lowering boot pulley. It is important that the boot pulley
and shaft are checked and maintained to be horizontally level.
Manual Screw Take-Ups
1. Turn the take-up screws on each side of the boot to control the boot pulley position.
2. After each adjustment, ALWAYS lock each take-up screw in position with the lock nut provided.
Gravity Take-Ups
Weight provides the tensioning method for gravity take-up.
NOTE: The weight box may not require any additional weight because the weight of the belt, cups, weight
box assembly and boot pulley assembly provide adequate tensioning in the belt to eliminate
slippage at the head pulley.
If additional weight is needed:
1. Add weights (not included) - Do not use increments of greater than 100 pounds.
2. Equally distribute weight from side to side for proper belt tracking.
3. Use the bearing plate adjustment screws to level the boot pulley after any needed weight is added.
CAUTION
DO NOT OVER TIGHTEN BOLTS.
CAUTION
Over tightening can lead to breakage.
