7.6. FIXED TRIPPER - ALL MODELS
Fixed trippers must be installed correctly to ensure proper operation. The
following list indicates the critical areas:
1. Conveyor
trunking
and tripper sections must be straight and square.
a. This should have been checked during installation with a laser or wire. The
conveyor must meet a +/- 1/8” tolerance. A level must be placed exactly
90° from the centerline to ensure conveyor is not twisted.
b. The tripper trunking sections must be installed in the correct order. The
trunking sections leading into the tripper section are higher than the normal
sections. The idler height continues to rise in each section so the belt line
gradually inclines to the top tripper pulley. See Figure 7.29. The sections
are numbered to make sure the sections are installed in the correct order.
