The invention provides an elastic crawler belt capable of easily detecting breakage of a steel cord and a method for detecting breakage of the elastic crawler belt. An elastic crawler (11) is provided with: a crawler body (11a) formed in a ring shape and comprising a rubber-like elastic body; a tensile body (40) that is embedded in the crawler body (11a) and that is wound in the circumferential direction of the crawler body (11a); and a plurality of core bars (30) which are embedded in the crawler body (11a) and are arranged at intervals in the circumferential direction of the crawler body (11a), the tensile body (40) is composed of a steel cord (41) wound in a spiral shape along the circumferential direction of the crawler body (11a), and the steel cord (41) is electrically connected to the plurality of core bars (30) only at one end (41a) and the other end (41b) in the longitudinal direction of the steel cord (41). One end portion (41a) and the other end portion (41b) are respectively connected with a first core bar (30a) and a fourth core bar (30d) which are different core bars (30).
本发明提供能够容易地检测钢帘线的断线的弹性履带及其断线检测方法。弹性履带(11)具备:履带主体(11a),其由橡胶状弹性体构成且形成为环状;抗拉体(40),其内置于履带主体(11a),并在该履带主体(11a)的周向上卷绕;以及多个芯骨(30),它们内置于履带主体(11a),并在该履带主体(11a)的周向上隔开间隔配置,抗拉体(40)由沿着履带主体(11a)的周向被卷绕成螺旋状的钢帘线(41)构成,钢帘线(41)仅在该钢帘线(41)的长度方向的一端部(41a)以及另一端部(41b)与多个芯骨(30)电连接,一端部(41a)和另一端部(41b)分别与不同的芯骨(30)即第一芯骨(30a)和第四芯骨(30d)连接。
