Raymond BL834 Leaf Chain Connecting Link 1 Inch Pitch – RA1039062

A connecting link joins two ends of BL834 leaf chain into a continuous run or closes a chain around a sheave, and this Raymond master link is built to the BL834 standard at a 1.00 inch pitch to do exactly that on mast lift chain. Its 3 by 4 plate lacing, 0.375 inch pin diameter, and 0.950 inch plate height match the BL834 chain profile, so the link's plates and pins interleave with the running chain and carry load without a weak transition at the joint. Built to ANSI B29.8 and ISO 4347, it shares the roughly 34,500 pound average tensile strength class of the chain it completes.

Leaf chain in a mast carries the lift load through the hydraulics, and the connecting link is the component that ties the chain into a working loop, so it has to hold the same tension as every other link across repeated lifting cycles. A link that is mismatched or worn at the joint is where a chain assembly tends to fail first. As a Raymond BL834 link it reproduces the OEM master link for these mast chains.

Confirm the chain is BL834 at 1.00 inch pitch with 3 by 4 lacing before fitting, since leaf chains of different pitch and lacing look similar but will not interleave or share load correctly.
