Round Link Mining Chain

Round Link Mining Chain

Product Description:

Round link mining chain is of high-tensile, used on conveyors and coal ploughs. The chains are not suitable for lifting or suspending. It meets the requirements of GB/T 12718-2009. The round link mining chain features high tensile strength, safety and excellent abrasion resistance. The material diameter ranges from 10 mm to 42 mm.

Note: 1. The straight side diameter of the chain link refers to the average value of the measured values of the same cross-section in two directions perpendicular to each other. 2. The minimum inner width a and the maximum outer width b of the link are measured on the width of the straight side outside the welding part. 3. The arc radius r is measured in the arc area between 1.2d and 120°.
