INSTALLATION OF POLYTIER SUPPORTS
CEILING HANGERS AND POLYTIER SUPPORTS
INSTALLATION OF CEILING HANGERS
NOTE:
To install, raise conveyor to
desired elevation, place cross pipe
underneath lower conveyor flange,
attach cross pipe to upright legs and use
U-shaped retainer (“hat”) bracket to con-
nect cross pipe to lower conveyor flange.
Polytier supports provide convenient
installation method for two or more tiers
of conveyor. To install, raise conveyor to
desired elevation (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 conveyor 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 illustration
above) offers lowest unit elevation, 0” +
depth of frame utilizing L-shaped mounting
bracket. Standard elevation style offers
unit elevation of 3-1/2” + depth of frame
and includes bracket welded to cross pipe
which is bolted to upright legs during instal-
lation.
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.
*NOTE: Overall conveyor height is dic-
tated by type of drive assembly used--i.e.
underneath, center drive, side mount, etc.
WARNING: It is the responsibility of the
customer and installation personnel to sup-
ply and install net or mesh guarding on
conveyors mounted overhead to prevent
product and/or debris from falling to floor
in areas where required.
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 levelled across bed width, tighten
locking bolts in U-shaped bracket
to secure position of cross pipe.
