As the lifting screw trans lates through the body of the jack, in her ent screw rotation is prevented by an attached load or mounting structure that is anchored to resist rotation.

This ec cen tric i ty will tend to increase with greater distance and higher loading. For this reason, double-clevis jacks are severely limited both in capacity and max i mum length. Double-clevis mounting differs from trunnion mounting because the pivot is located further from the jack body. The column load charts do not apply for this mount ing, please consult the factory...
