Compression Tests
 

Results :

The displacement of the jack head depending on the applied load is presented in the figures 2 to 17 . The tables 3 and 4 give the max. load for each test.

SECURITY VALUE FOR ADMISSIBLE MAXIMUM LOAD

1 ) Security for human passage in contexts such as terraces
value to be divided by 2

2 ) Security for industrials raised floor platforms
value to be divided by 4

ex : centric load of P4 at 160 mm ( 3550 kg : 4 ) = 887,5 kg / pedestal
