Flatness
See Figure 4-16 for the following procedure:
1. Lay the strap on a flat surface. Do not block the strap
or it may sag.
2. Stretch a line (string or wire) across the top surface of
the strap from the pin storage hole at one end of the
strap.
3. Stretch the line as tight as possible and tie it off at the
other end.
4. Check that line touches the top surface of the strap at all
points along its length.
5. If the string does not touch the strap, measure the
distance from the line to the strap.
If deviation from straight is greater than the maximum
allowed, remove the strap from service.
6. Remove the line. Turn the strap over.
7. Repeat steps 1
through 5 above.
Elongated Hole
See Figure 4-17 for the following procedure:
1. Insert the pin into the hole.
2. Push the pin tight against the edge of the hole along the
horizontal center line. Measure the dimension between
the pin and the hole (View A).
3. Push the pin tight against the edge of the hole along the
vertical center line. Measure the dimension between the
pin and the hole (View B).
If dimensions A and B are not identical, the hole is
elongated. Remove the strap from service.
If the two dimensions are identical, but greater than 0,8
mm (0.030 in), contact the Manitowoc Crane Care
Lattice Team.
