Hytrol Minimum Pressure Live Roller Conveyor 190-ACZ

It is important that each bed section be checked for an out-of-square condition. If conveyor is not square, tracking prob- lems will result. Figure 17A indicates a racked section.

TO CORRECT AN OUT-OF-SQUARE SECTION

1. Locate points on corners of section and measure distance “A” & “B”. If the dimensions are not equal, the section will need to be squared. (Figure 17B).

2. Use crossbracing supplied on underside of conveyor to square each section. Adjust turnbuckle until Dimensions “A” & “B” are equal.

3. After all bed sections have been checked and corrected for “racked condition”, tighten all butt couplings and pivot plate bolts.

4. Make final check to see that all conveyor sections are level across width and length. If entire conveyor is level, supports can be lagged to floor.

IMPORTANT: Being out of level width of conveyor can cause package drift on long conveyor lines.;

Warning: This procedure requires trained personnel with PPE!

Is the drive chain pre-lubricated from the manufacturer?

If not, apply a good grade of non-detergent petroleum or synthetic lubricant (i.e., Mobile 1 Synthetic)

Enter the hours of operation since last lubrication

Enter the date of last lubrication

Select the operating environment

For harsh conditions, it is best to lubricate more frequently and develop a custom lubrication schedule

Enter any notes or observations about the drive chain condition

Sign off on the drive chain lubrication

Loosen bolts in Pressure Adjustment Angles

Raise Pressure Adjustment Angles until proper force is obtained

With conveyor running, reduce pressure on all tread rollers to zero by loosening the knurled adjustment nuts

Place heaviest item to be conveyed on infeed end of conveyor. Increase pressure under the item by tightening the knurled nuts

As the item moves, continue adjustment ahead of item until it moves the entire length of conveyor

Return item to infeed end of unit. It should now travel the entire length of conveyor. If not, repeat the adjustment procedure in the problem area

IMPORTANT: The drive belt should be checked for proper tracking prior to installing tread rollers. This will allow easy access to items that might need adjusting.

Conveyor is level across the width and length of unit

All pulleys, return idlers, and snub idlers are square with conveyor bed

Belt has been properly threaded through conveyor

IMPORTANT: When belt tracking adjustments are made, they should be minor (1/16 in. at a time on idlers, etc., should be sufficient.)

Give the belt adequate time to react to the adjustments. It may take several complete revolutions around the conveyor for the belt to begin tracking properly on long, slow conveyor lines.

Belt is traveling in the correct direction
