Lifting Angle Load Factors Dynamic/Shock Load Factors All load values shown in the ALP Supply lifting charts are based upon a smooth engagement of the lifting anchor, utilizing cable rigging on a smooth surface. The load transmitted to the anchor should be increased by the following factors.

30 SPA 45 SPA 60 SPA 90 SPA

120SPA NOT ALLOWED

TL VCA

Sharp rigging angles can drastically increase the load transmitted to a lifting anchor. Spread Angles (SPA) less than 60 are preferred to minimize this factor.
