THE PIT FRAME
Step 5.
Set the frame in the hole supported at
about the correct height.
Step 6.
Set two 2 x 4 's on edge (longer than the
width of the hole) across the opening. (See
Fig. 7)
Step 7.
Use soft wire and make 2 loops by twist-
ing wire around each 2 x 4 and the frame
Step 8.
With the frame supported by the wire and
2 x 4's, use a spirit level to set the frame
flush with the surrounding floor, level the
frame to within 1/8”, corner to corner, side
to side and diagonally, and at the correct
height by twisting or untwisting the wires.
(See Fig. 7)
Step 9.
Concrete specifications:
•
At least 6” thickness of concrete is required
for pit floor in Non-Hostile applications.
•
At least an 11” concrete floor with a mini-
mum of 3” bottom slope is required if drain-
age is required for hostile applications. A 4”
drain is highly recommended.
•
Make sure the conduit for the scale cable is
in place and secured into the frame opening.
•
Pour the concrete around and under the
frame ensuring a smooth and level finish. It
is recommended that f = 3500 psi and 3” to
4” slump concrete be used.
•
If a drain is required, form the pit to place a
slope in the pit floor to the drain. (See Fig.
23)
