Shift chain is the next generation cable of chain developed to protect the inner cables and hoses applied to equipment and machinery of overall industries with the unique structure, is a new concept that the value of Bending Radius is decided by the independent Bending Radius unit inserted. As BR unit (Bending radius unit) has 6 points of supporting area when inserted into side band, its durability and self-supporting level are 30% longer. Shift Chain is produced with high-quality engineering plastic material, which have strong durability and great abrasion resistance, so the chain has less breakage possibility by outside damage and performs stable cable protection in any difficult environment. As the chain is verified through the tests for electrostatic discharge (ESD) and explosion proof (ATEX-Directive 94/9/EC), it can be used in operation of electric equipment and machinery. Also, the chain is UV-coated, and can protect cable in outside installation. Furthermore, the chain is produced with high-quality engineering plastic, which include none of the 6 harmful substances (restrictive in the Europe market); Lead (Pb), Cadmium(Cd), Mercury(Hg), Hexavalent Chromium (Cr6+), PBB, PB DEs etc. and which is recyclable and harmless both to user and environment available in N-Type (Both Side Open), Semi Enclosed (One Side Enclosed), E Type (Both Side Enclosed) RS Type (Sliding with Roller Skid), ERS Type (Enclosed Sliding with Roller Skid).
