Install Tow Tongue / Spreader Bar:
1)
The mounting brackets for the tow tongue are to be installed on the first and second
frame leg, from the tow end of the bleacher. The location of the brackets, side to
side, needs to be determined. Since the bleacher has more weight towards the back
rows, the location of the tongue needs to be shifted towards that side – not centered.
On a 5-row bleacher, the tongue will be located to the right of the vertical support for
the fourth row (see figure 5). To determine the proper location, lift and place the end
frame on a jack stand or block of wood or concrete – located off the centerline
towards the top row. Make sure both wheels are blocked on both sides. Move the
stand or block from side to side until the load appears to be balanced. Mark this
location.
2) Center one of the tongue mounting brackets (4) on the location line and using a 7/16”
transfer punch, mark and drill two 7/16” holes exactly 4-1/2” apart. Install the
tongue-mounting bracket as shown in Figure 7.
3) Measure the location of the tongue-mounting bracket on the first leg and install a
bracket, in the same location, on the second leg.
4) Attach the tow tongue (1) to the two mounting brackets using the hardware shown in
Figure 8.
5) If being installed on a 21 ft bleacher, with four legs, install the spreader bar (6) on the
second and third legs. Locate the mounting brackets and spreader bar to either side of
the tow tongue.
