two diagonals, the frame is not square. A “racked” conveyor will skew the rollers, causing the belt to
wander off center.
The conveyor sections are joined together with welded butt plate connectors. If a conveyor section is
determined to be out of square, adjustment must be made before proceeding to the next section.
Correct the squareness of the conveyor frame by installing a tie rod along the longest diagonal
dimension and adjusting the turnbuckle until the diagonal measurements are equal in length. It is
important to loosen the support and connection hardware before attempting any adjustment.
If gaps appear between bed joints as a result of squaring the conveyor, take care not to “re-rack” the
conveyor by pulling the sections together at the bed joints. Insert optional shim plates or washers to
the required thickness to fill the gap before tightening the connection hardware. Verify the squareness
of the conveyor after installation.
An out of square conveyor section is a leading cause of belt mistracking.
