• Belt Installation

The conveyor belt has been cut to the proper length and lacing installed at
the factory. To install follow these steps:
1. Thread belt through conveyor as shown (figure 4B).
2. Pull ends together and insert lacing pin (figure 4A).
3. Adjust belt tension with take-up pulley or tail pulley. Keep pulley square
by moving both take-up bolts an equal amount. maintain enough tension
so drive pulley will not slip when carrying the rated load.
4. Track belt per instructions on Pages 5-6.
NOTE: If belt ends cannot be
pulled together by hand, it
may be necessary to loosen
take-ups (at tail pulley, etc.),
minimum position or use a
belt puller so lacing pin can
be easily inserted.

Excessive slippage will reduce belt life and damage drive pulley lagging. Never apply more tension than is needed.
Over-tension will cause extra wear to belt and bearings and will require extra power from drive.

• Racked Sections

It is important that each bed section be checked for a "racked" or out-of-
square condition. If conveyor is not square, tracking problems will result.
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 5A).
2. Use crossbracing supplied on underside of conveyor to square each sec-
tion. Adjust turnbuckle until dimensions "A" & "B" are equal.
3. After all bed sections have been checked and corrected for "racked condi-
tion", 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.
Being out of level across width of conveyor can cause package drift on
long conveyor lines.
