Hytrol Hytrol Conveyor 190-LR

Warning: This procedure requires trained personnel with PPE!

Drive chain pre-lubricated from the manufacturer?

Enter the date of last lubrication

Choose the type of lubricant used

Was a brush used to lubricate the chain?

Note: The proper viscosity of lubricant greatly affects its ability to flow into the internal areas of the chain.

Check if any of these harsh conditions apply

Enter any additional notes or observations

Warning: This procedure requires trained personnel with PPE!

Check for out-of-square condition

If conveyor is not square, tracking problems will result.

Are dimensions 'A' & 'B' equal?

If dimensions are not equal, adjust turnbuckle until they are.

Check if all bed sections are corrected for 'racked condition'

Tighten all butt couplings and pivot plate bolts after correction.

The Model “LR” &“ACZ” conveyors are equipped with “pop-out” tread rollers that are removed before installation. After the belt has been installed and tracked properly, the tread rollers must be re-installed.

On all but three rollers at either end of unit, they are simply dropped into the slots in the frame channels.

To drive the end rollers, they are connected with “O”-Rings as shown in Figure 23A. Note that the center roller has two grooves and the others have only one.;

Warning: Ensure the machine is turned off and unplugged before starting the procedure.

Determine the top and bottom sides of the belt

The bottom side of the belt will be marked 'THIS SIDE DOWN'.

Pull belt ends together and insert lacing pin

For maximum efficiency, maintain enough belt tension so drive pulley will not slip when carrying the rated load.

Adjust belt tension with the take-up pulley or tail pulley

Keep pulleys square with bed by moving both take-up bolts and equal amount

Sign off on the belt replacement

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

Condition 1: Belt is running in the direction (FLOW) with the arrow, but tracking (drifting) towards Side “X”

Condition 2: Belt is running in the direction (FLOW) with the arrow, but tracking (drifting) towards Side “Y”

If Belt Direction (FLOW) is reversed, all the above conditions will remain the same as in Figure 22A, except you are now viewing the conveyor from the opposite end

If belt continues to track improperly, re-check all items covered in “Pre-Tracking Inspection” and make corrections as necessary.
