How do I correctly tension my slider bed conveyor belt?
- Make sure belt tension is tight enough so cleats are not rubbing the bottom guards. This comes pre-set from manufacturing but please double check.
- Do a visual check to ensure the belt is not slipping (the head pulley spinning without the belt moving).
- Do a listening test to hear if there is any belt slippage at the head pulley or if there are squeaks or abrasive sounds.
- If the belt needs to be tensioned you do this at the take up.
- With the conveyor stopped and the E-Stop pressed (so it cannot run). Start by removing the take up guards on both sides.
- Release the jam nut so that you can turn the take up all-thread rods. To add belt tension loosen the top nut and slide the tail pulley back. Make sure and count the number or turns you put on the nut. That way you can match it on the other side. It is important that the take up distance is set exactly the same on both sides of the conveyor. Check to ensure that the pulley is moving towards the closest end of the conveyor and adding tension to the belt.
- Tighten the jam nuts to lock the take up in place once you have tensioned the belt enough so that is will not rub on the bottom guards and will not slip at the head. Double check that the take up distance is the same on both sides. This can be done by measuring from the plate the nuts push against to the face of the bearing.
- Re-install the take up guards now that the take up has been adjusted and locked. Start up the conveyor and check visually and by listening to make sure that it is properly tensioned.
