5.4.4 Using Multiple Jacks
If using more than one jack to raise a load, all the jacks must
be able to individually raise the load e.g., two PS620 jacks
cannot be used to lift a 30T load as it impossible to pump
both jacks at exactly the same rate, or lower the jacks at
exactly the same rate. One of the jacks will end up with an
excess load and is liable to fail. In such case two PS630 jacks
should be used to raise a load of 30T.
When using multiple units to lift a load, all jacks must be
operated at the same time, so that the load is lifted evenly.
