Series 2 Chain Conveyors
An en masse conveyor may be purchased with
unassembled trough sections. The following recommen-
dations may prove useful in their assembly.
Before assembling conveyor trough sections together
remove covers. It is recommended that you store your
covers in a protected area in order to minimize any pos-
sible damage. Remember to retain factory shipped hard-
ware for conveyor cover installation.
Take a moment to familiarize yourself with your trough
assembly. Install the slide rail returns so that the wide
ends of the rail returns face away from the discharge end
of the conveyor. The narrow end, therefore, will face
toward the discharge end.
Intermediate trough sections are supplied in standard
ten foot (10’) lengths. Depending on your application
and individual specifications however, shorter sections
may be required to accommodate a desired overall length.
During assembly of each trough section to the next sec-
tion, carefully inspect each flange joint to ensure that the
inside bottom and side surfaces of the troughs are flush.
A chalk line is helpful during this phase of the assembly
to ensure the proper alignment of the trough surfaces.
The maximum run-out in any direction should be
+/- 1/4”. This proper alignment will minimize wear on
flights and other potential damage to the conveyor. Make
sure the conveyor is level in horizontal applications.
Proceed by attaching the head and tail assemblies using
the same alignment procedures and precautions noted
in the preceding paragraph.
Installation
Fasten covers to the enmasse conveyor with the 3/8”
and 1/2” hardware provided. Adequately tighten the
1/2” bolts and nuts so that the vertical cover seams are
in tight contact with each other.
When an inlet is on the conveyor, a cover section may
have to be cut accordingly to accommodate the inlet.
For installation of an inlet, see Inlet Assembly and
Installation below.
Inlet Assembly and Installation
One inlet is typically provided per conveyor. GSI’s rec-
ommendation for inlet installation includes a minimum
distance of no less than 6” between the closest edge of
the inlet and the tail assembly. See detail on page 12.
The inlet can be attached with continuous weld seams.
If intermittently welded, it is important to use caulking
or sealing around the inlet area in order to seal the unit.
Similarly GSI recommends that if inlets are welded onto
the conveyor, this procedure should occur prior to instal-
lation of motor and/or other electrical devices. By not
following this precaution, owner assumes all risks asso-
ciated with this type of installation.
Cover Assembly
Installation
Lay bottom plate weldment onto blocking material.
Next, loosely attach side weldments to bottom plate
with 3/8” hardware provided. Then fasten slide rail
return weldment to intermediate sides with the 1/2”
hardware.
Note: It is critical for straightness of the conveyor
that the sides and bottom flanges are aligned flush.
Also, it is important that the inside dimensions of
the box measure equidistant from side-to-side both
top and bottom of the trough box (Dimension A =
Dimension B). See diagram below.
After making sure the flanges are aligned, tighten all
hardware on the trough section. Abrasion Resisting
(A.R.) liners are installed with the 3/8” flat countersunk
hardware provided. Adequately tighten liners to con-
veyor sides. Check that the countersunk hardware is
not protruding above the surface of the A.R. liners.
