SPECIAL DESIGN LEAF CHAIN

For particularly high loads applications, we recommend leaf chains with special design as T-CHAIN (patent pending) to extend chains service life.

 1. STANDARD CHAIN CONSTRUCTION：

1.1 DISADVANTAGE of STANDARD CHAIN：

1.       Pins are locked and press fit only with two outer-plates on each end according to standard chain construction. When a standard leaf chain transports a heavy load which is larger than the lock-on strength between pins and plates, pins would start to turn. And chain life would deteriorate sharply cause of holes continue enlarging by turning pins.

2.       With standard leaf chain all plates are mounted with a sliding fit but only two outer-plates are press fit plates. No pre-stress strength applied on sliding inner-plates, chain fatigue strength will be therefore relative lower.

1.1 標準Leaf Chain結構缺點：

1.      銷軸僅靠外鏈板緊配合之嵌合力固定，承受重負荷轉動時，銷軸會因扭轉力量大於嵌合力而產生轉動，進而造成外鏈板孔磨損，使鏈條的使用壽命縮短。

2.      外鏈節除外鏈板外，餘內鏈板與銷軸皆為鬆配，內鏈板無法產生預留應力，鏈條疲勞強度較低。

2. T-CHAIN CONSTRUCTION：

2.1 T-CHAIN FEATURE：

1.       A tightened press fit construction increases the tensile and compressive strength between pin with side-plates, and this design distribute the load evenly on pin, greatly level down a possibility of turning pin when chain transport heavy load. Chain life is significant prolonged as press fit design minimize a wear out problem caused by turning pins.

2.       Press fit construction greatly improves fatigue strength about 25% than standard leaf chain. See below comparison chart with standard leaf chain.

2.1 T型Leaf Chain特性：

1.      T型Leaf Chain結構可增強外鏈節與銷軸的嵌合力，避免銷軸因重負載而發生轉動，同時可防止外鏈板孔因銷軸異常轉動產生過度磨損，影響鏈條的使用壽命。

2.      T型Leaf Chain結構內鏈板與銷軸緊配，產生預留應力可提高疲勞強，經測試比標準結構Leaf Chain提高約25%：
