Important note - break loads
Where break and safe working loads are stated, it is assumed that all sheaves are evenly loaded as in a purchase tackle. Uneven loading, or loading of one sheave in a double or triple block, will severely affect strength quoted. If unsure, please seek further assistance. Maximum rolling load on ball bearing blocks is the maximum free running load before ball bearings will distort.
