A high-load block is designed to withstand significant working loads. It is used to multiply mechanical advantage or to reduce friction when the run of a line includes a sharp angle.
ApplicationsAs with other blocks, the various versions of these fittings include snatch blocks, becket blocks to create a block and tackle, swivel blocks and those attached by shackles and snap shackles. They are used wherever loads are significant and reliability requirements exceptional. Such blocks serve as deck-mounted halyard or sheet leads, as part of sheet tackle and in other situations.
TechnologiesCable blocks generally have stainless steel sheaves and cheeks. In contrast, those for rope line are often of aluminum, since they are subject to less abrasion and sheer strain.
Roller bearing blocks are the most efficient. The reduced contact between the axle and the sheave minimizes friction, as would ball bearings, but the additional width of the rollers distributes the load over a greater surface, making the block stronger than ball bearing or friction models. Some particularly high-tech versions are made of titanium, extremely light, but very expensive. They are generally only used by top-level competitive sailors.
Choice will depend on the block's precise function, the way it will be fastened and the loads it will have to bear.
