尼龍拖鏈長度的確定
固定點在運行中間位置時
Fixed point at the centre of total travel
拖鏈長度的計算取決于LA/2中心點到彎曲半徑的距離，這個值（b）會隨著拖鏈節距的變化而變化，適用于尼龍拖鏈和鋼鋁拖鏈。
The chain length(L) is calculated by summarising the half stroke LA/2 to the nominal value(b) of the bending radius.
The value is then rounded up the multiply of the chain's pitch for nylon cable chains and to an odd multiply for steel chains.
固定點偏離運行中間時
Fixed point not positioned at the centre of total travel
拖鏈長度的計算取決于LA/2中心點到彎曲半徑的距離，DPJ表示固定端偏離中心點的距離，這個值（b）會隨著拖鏈節距的變化而變化，適用于尼龍拖鏈和鋼鋁拖鏈。
The chain length(L) is calculated by summarising the half stroke LA/2 to the nominal value(b) of the bending radius and the distance()DPJ from fixed point to center of total stroke.
The value is then rounded up the multiply of the chain's pitch for nylon cable chains and to an odd multiply for steel chains.
