Product description
Calibrated long link chain to DIN 20637 for suspending monorail track in underground mines. The alloy steel chain is tested, and the manufacturer states it exceeds the standard's forces by about 10%.
Sizes and ratings
2 sizes, 16 × 80 mm to 18 × 90 mm. Minimum breaking force 180 to 250 kN; test force is listed for each size and grade. Every row has its own Indus part number in the table below.
Choosing a size
The table gives the link dimensions with test and minimum breaking force for each size. Use it for monorail track suspension as the mine's design specifies. It is conveyor and mining machinery chain, rated by test and breaking force; it is not lifting chain and carries no working load limit.
Ordering
Quote the Indus part number from the table, or send the size you need. Each consignment ships with the manufacturer's test certificate; say on the RFQ if your site needs anything more.

|---|---|---|---|---|---|---|---|

Size — Nominal size as the manufacturer states it. Proof load — Proof or test load the manufacturer applies to the part. A test figure — never a working limit. Min breaking load — Minimum breaking load. A test figure — never lift to it. Material dia. — Diameter of the link or bar stock. Inside width — Inside width of the link or jaw. Pitch — Thread pitch or link pitch, as the source heads it. Weight — Weight per metre, as published. Ask us for the dimension drawing if you need it stamped.
WLL is the most the part may carry in service. Proof and breaking loads are test figures — never lift to them. Each load is shown in the unit the manufacturer rates the part in, and a size ships with the manufacturer’s test certificate.
This range is published with a breaking load only, not a working load limit. Tell us the duty before using it to lift, and we will confirm a rating or recommend a rated part.
