| IMPORTANT NOTICE: Break Loads |
|
Where break and safe working loads are stated, it assumes 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 advice. Maximum rolling load on ball bearing blocks is the maximum freee running load before ball bearings will distort. |
