WFC elevator balance compensation chain elevator products WFC/EB is evenly coated a PVC liquid layer out of high-quality electric welded chain, then the chain is heated and solidified and finally forming compensation chain in chain shape. The gaps between the links are clear, no noise, low cost. WFC/EB overcomes the shortcoming that PVC-Coated chain is easily tear. It's used for the elevator with rated speeds of below 1.75 m/sec. basic parameters Model No Unit weightExternal diameterAllowed least curvation diameterDiameter of linkBroken loadWFC0500.88±0.2021.0±2.0280.06.0±0.5≥15.63WFC0751.12±0.2026.0±2.0280.07.0±0.5≥18.132WFC1001.49±0.2029.0±2.0300.0 8.0±0. 5≥23.68WFC1251.88±0.2032.0±2.0300.09.0±0. 5≥29.97WFC1502.24±0.2036.0±2.0300.010.0±0. 5≥37.00WFC2002.98±0.2039.0±2.0300.011.0±0. 5≥44.70WFC2503.73±0.2046.0±2.0300.013.0±0. 5≥62.53WFC3004.47±0.2050.0±2.0320.014.0±0. 5≥69.93WFC3505.22±0.2053.0±2.0320.015.0±0. 5≥83.25WFC4005.96±0.2056.0±2.0320.016.0±0. 5≥94.72
