The C-FLEX Elevator Belts are constructed with specially designed straight warp "open type" steel cords with built-in elasticity, E-cords, in the warp direction onto which rigidity improving weft cords are tied using a special weaving techniques. This special structure means that neither the warp nor the weft cables are deformed in any way, but they lay perfectly straight all over the belt length, resulting in maximum strength performance and high resistance to damage. The open steel E-cords allow maximum rubber penetration, minimizingcorrosion penetration in case of belt damage and resulting in very high rubber to steel adhesion. The rubber penetration deep into the warp cables functions as lubricant for the twined steel wires forming the cords increasing the elasticity of the E-cords.
Low Elongation
C-FLEX elevator belts display only 0.3% permanent elongation at maximum recommended working load (safety factor 10), ensuring consultant belt tension, even at long centre distances. As a unique feature the steel carcass displays an elastic elongation of 0.15%, increasing shock resistance and allowing the belts to run over slightly crowned pulleys,thus further greatly improving the straight tracking ability of this belt quality, The elastic elongation is the variation in belt length when subjected to a load variation between 20% and 100% of the maximum recommended load at 10-fold safety factor.
