6.6 REAR TIE BAR INSTALLATION
1.
Raise lift to working height and lower onto safety.
2.
Have 2; ½”-13UNC x 1½” long hex head bolts, flatwashers, lockwashers and nuts ready
to support the tie bar when it is raised into place.
3.
Raise the rear tie bar into place making sure the slotted holes are up and the nose-like
protrusions are pointing toward the front of the units. The vertical members on the tube
should be on the outside of the deck skirts. Line up each vertical section slot with the
respective slot on the deck and place the bolts with washers through, one on each side.
Put the flatwashers and lockwashers and nuts on the inside of the decks.
DO NOT TIGHTEN!
4.
Install 2; ½”-13UNC x 1½” long hex bolts, flatwashers and lockwashers to each end of
the tie bar positioned under the deck.
DO NOT TIGHTEN!
5.
Now install the remaining 6; ½”-13UNC x 1½” long hex bolts, flatwashers, and
lockwashers to the tie bar.
DO NOT TIGHTEN!
Baseframes should be level before
tightening, Refer to leveling procedure (following section).
6.7 LEVELLING
PROCEDURE
NOTE: This is a very important procedure and time must be taken to do it correctly.
1.
The highest point on the floor, noted from Section 4.1 step 6 is the point from which the
base frame will be levelled from. A quick check using a four (4) foot level across the
base frame should again verify that this is the highest point.
2.
Starting at the corner closest to the highest point, check along the length of the base
frame edge with the four foot level and shim as required
. NOTE THE FIVE CRITICAL
POSITIONS THAT SHIMS MUST BE PLACED ON EACH BASE FRAME OF
EACH MAIN FRAME ASSEMBLY
. Refer to
Figure 5
.
3.
Continue shimming across that base frame from side to side, and front to rear.
4.
Once one frame is completely leveled, level the inside rails of the base frames to one
another.
5.
Now level the remaining outside half of the last base frame by placing the level across
that unit and shimming as required.
6.
A quick check across, along and between each base frame will ensure the levelling
procedure was carried out successfully. Re-adjust the tie bars if necessary.
LEVELLING EXAMPLE: FIGURE 5
Assuming that the front right corner is the highest point level in the following order:
- Shim along side “A”
- Shim across from side “A” to side “B” (check along side “B” from front to back)
