Selecting the right option
BL leaf chain uses the next larger pitch size of plate, for medium loads with more shock. Match pitch and lacing to your sheaves and anchor.
In Sugiyama's leaf chain numbers the leading digits give the pitch (in eighths of an inch) and the last two digits give the lacing, for example BL466 is 1/2 in pitch with 6 x 6 lacing.
Fitting and use
Fit the retaining clip or pin the way Sugiyama shows: spring clips go on with the closed end pointing the direction the chain runs, cotter pin prongs are opened to a 60 degree angle, and cotter pins must not be re-used. Use the clip or pin supplied with the link.
Chain drives should be guarded. Lock out machine power before removing, installing or servicing chain, wear eye protection when driving or grinding pins, avoid welding or plating assembled chain, and never repair damaged chain by replacing only some of its parts.
