Polytier supports provide convenient installation method for two or
more tiers of conveyor. To install, raise conveyor to desired eleva-
tion (approximate). Place 1” inside diameter cross pipe underneath
lower conveyor flange. Attach cross pipe to upright legs. Use
U-shaped retainer (“hat”) bracket to connect cross pipe to lower con-
veyor flange. Do not tighten
fully at this time.
There are two styles of attachment brackets available for use with
polytier supports. Minimum elevation style (see TyPE “0”, illustra-
tion above) offers lowest unit elevation, 0” + frame depth utilizing
L-shaped mounting bracket. Standard elevation style offers unit
elevation of 3-1/2” + frame depth and includes bracket welded to
cross pipe which is bolted to upright legs during installation.
When unit is at operating elevation and unit has been checked
across width for level, tighten locking bolts in U-shaped bracket.
Add knee braces for unit rigidity.

INSTALLATION OF CEILING HANGERS
Ceiling hangers are frequently used in high-elevation applications for suspension
from ceiling. The 5/8” diameter (#11 UNC) all threaded rod is supplied to allow
infinite vertical adjustment along the length of the suspension rod (see illustration
above).
Attach and firmly tighten U-shaped retainer (“hat”) bracket to underneath side of
lower conveyor flange with hardware provided
to hold cross pipe (1” inside diameter) against underneath side of conveyor.
Do not tighten cross pipe locking bolts (these attach in the bottom of the U-shaped
retainer bracket) until threaded suspension rods have been firmly secured to ceiling
structure.
To adjust conveyor elevation, tighten or loosen lower nut and jam nut on threaded
suspension rods to desired elevation. A lock washer must be used on suspension
rods to maintain unit at desired elevation. When unit is at operating elevation and unit has been leveled across bed width,
tighten locking bolts in U-shaped bracket to secure position of cross pipe.
It is the responsibility of the customer and installation personnel to supply
and install net or mesh guarding on conveyors mounted overhead to pre-
vent product and/or debris from falling to floor in areas where required.
POLYTIER SUPPORTS, CEILING HANGERS AND UNDERTRUSSING
INSTALLATION OF POLYTIER SUPPORTS
When installing some conveyors, using a permanent support or ceiling hanger is sim-
ply not practical. In this situation, three bed sections (maximum) may be joined togeth-
er utilizing truss assembly, mounted underneath conveyor (see illustration at right).
Adjoin beds on floor using both connector rod support assemblies and connector rods
(5/8” diameter-11UNC threaded rod). The diagonal connector rod is used not only to
support the intermediate bed section joint but it is instrumental for setting and maintain-
ing proper tension across intermediate spanned beds.
Use mechanical hoist (fork truck or other means) to raise pre-assembled bed sections
(with undertrussing) to desired elevation for final installation.
Use diagonal connector rods to level the undertrussed beds both along and across
the conveyor. Remember that the tension must provide adequate for both dead load
(conveyor weight) and product load during unit operation. It is the responsibility of the customer and installation personnel to supply and
install net or mesh guarding on conveyors mounted overhead to prevent prod-
uct and/or debris from falling to floor in areas where required.
