Before the drop height is calculated, it is necessary to select a weight setup (240, 340, 540 or
740 kg). To do this, use the following Table 4 showing the usable load ranges for each weight
setup:

Example 1 (UUFWDUU ONLY!):
If you want an approx. peak load of e.g. 11,000 lbf. (50 kN), then it can be seen from Table 2
that
the 250 kg (550 lb.) weight setup
OR the 350 kg (770 lb.) setup
can be used, and then Table 1 gives:
250 kg (550 lb.): k = 935 lbf
OR 350 kg (770 lb.): k = 1,350 lbf
