LEVATIONS
All top-of-belt (TOB) heights should be installed in accordance with the elevations shown on the
drawings. In addition, all sortation devices must be level across both the frame width and length.
Leveling of the frames is best done using a rotating laser level along the length of the conveyor and a
builder's level across the width.
After the first elevation is established at a critical point, the elevation of all other points shall be relative
to this first point. Normal practice is to dimension the layout and measure elevations from the floor at
each point of support.
As the conveyor system proceeds onto another floor or into another building or room, a new elevation
will be measured from the floor at that point. This new elevation will then become the reference for
subsequent elevations.
When installing an overhead system, the first elevation is measured from the floor and becomes the
reference elevation point until a change in elevation is shown on the layout. Any new elevation is also
measured from the floor and becomes the new reference point. The process is repeated each time an
elevation change occurs.

RRANGEMENT
Floor Supports
Install bolts used to attach the standhead to the frame so the nut is on the bottom. Standhead bolts
should be left finger tight while the conveyor is being assembled and aligned.
Floor supports are ordered by nominal height range, which is the dimension from the floor to top of the
support. Conveyor elevations are shown on the layout by top-of-belt elevations. The difference between
top of belt (TOB) and top of support is 7-3/8” and 9/58” end pulley and 13 1/16” direct drive bed. This
dimension must be subtracted from the TOB height to set support height.
It is important that conveyor frames be installed level. Floor supports will accommodate normal
irregularities in the floor surface. Adjustment for elevation in floor supports is accomplished with metal-
on-metal bolt clamping force. To achieve the support's stated load rating, it is necessary to tighten the
elevation adjustment bolts (3/8" diameter) to 23 ft. /lbs. of torque.
Supports should always be installed in the vertical position, and any variations due to conveyor pitch or
floor slope will be compensated for in the pivoting stand-head of the support.

Consult the building architect or a structural engineer regarding ceiling loading or
structural limitations of the building if any conveyor is ceiling hung.
