CONNECTORS
Adjoining beds may be connected using optional
stand- head connector plates (one on each side).
Connectors are normally used with ceiling hangers
when the hanger is not centered on the frame joint.
The hanger should be within 1' of the joint while
maintaining 10' maximum centers. The beds should
be temporarily supported while the support and
connectors are installed.
Each standhead connector uses two bolts through
the flange of the frame plus two bolts through the
vertical leg and conveyor channel web.
Beds should be checked for squareness before
final tightening of bolts.
Welded butt bolt connectors may be used to join two
straight frames, straight to curve, straight spur or 4-
1/2" to 9" deep frame (urethane belt transfers).
Welded butt bolt connectors must be ordered on
designated bed frames.
Welded butt bolt connector available for 4-1/2" deep
frames. They are standard with 9" deep frames.
U-shaped butt bolt connectors are commonly used
to connect a 4-1/2" channel frame to a urethane belt
transfer which uses a 9" deep frame. The UBT has
pre-welded butt bolt plates in each end.
The spacer channel connector kit consists of two
formed channels 4-1/2" deep with mounting
hardware. This connector is a standard component
of ceiling hangers but is also used to allow a support
on the frame joint between 4-1/2" and 9" deep
channel frames. This is another choice to join a 4-
1/2" channel to a UBT frame.
A 4-1/2" deep spacer channel bolts to bottom flange of 4-
1/2" deep bed and standhead of the floor support or a
ceiling hanger.
KNEE BRACES
Stability along the conveyor length is achieved with
knee braces. Braces resist stresses caused by
direction of product flow, drives, stops and starts.
Every support does not require bracing. Braces are
used at the ends of straight runs and approximately
every 30' in between. Braces should be located
toward the discharge end (DOWNSTREAM) side
putting them in tension. Starting the conveyor puts
opposite stresses on the supports, which is resisted
by installing a brace near the drive toward the
receiving end (UPSTREAM).
For best results the angle between the knee brace
and frame should not exceed 45 degrees, or be less
than 30 degrees. On short supports where a small
angle results, the knee brace may need to be
shortened.
Type "C" braces (not shown) use two type "B"
braces overlapped and bolted together for extended
length when conveyor height is 48" or more.
