When only one anchor point is applied then the allowable load can be determined as follows:
1. Read the value of the allowable load from the capacity chart
2. Calculate
the distance between the top of the capacity chart and that value
3. Add half of that distance to the indicated allowable load.
Example:
1. Assume the anchor is located in centre of the header beam.
For that location the capacity chart shown below indicates an allowable load of 300.
2. The distance between the top of the capacity chart and the curve is (900 – 300) = 600
3. The allowable load is 300 + 600/2 = 600
Enter the allowable load on the header beam in the checklist given in Appendix A
“ Checklist
for planning a lifting operation ”.
Caution: The force on each anchor point shall not increase the capacity of the
header beam.

Earlier purchased Enerpac / Hydrospex header beams may be applied if their
capacity is sufficient.
x
Header beams of foreign make can be applied if their capacity is sufficient, but
Enerpac will not take any responsibility for it.
