Disclosed is a balance compensation chain of a full-plastic elastic flame-resistant elevator, comprising a metal chain (3) covered by a covering layer (2). A sheath (1) is provided outside the covering layer. The metal chain (3) comprises two sub-metal chains. The two sub-metal chains are a first sub-metal chain (31) and a second sub-metal chain (32) respectively, and the second sub metal chain (32) is fixed on the first sub-metal chain (31) in a wound manner. The balance compensation chain of the elevator does not limit an ascending speed when the elevator moves up, has a large load capacity and a favored hanging perpendicularity, and is not easy to be distorted. |
