PROBLEM TO BE SOLVED: To provide the caterpillar band of an operating machine capable of easily scraping sludge attached to a track block.SOLUTION: A caterpillar band has several sets of a link having a pair of left and right link plates 20, 21 and is configurated into an endless chain shape by connecting both ends of the left and right link plates 20, 21 to each end of the adjacent link plates 20, 21 with a pin 23 and a bush 24. The female screw holes 22b are provided on protrusions 22a of track blocks 22, and through-holes 20g for installing the track blocks are provided on the link plates 20, 21. The track blocks 22 are installed to the link plates 20, 21 by screwing bolts 26 inserted in the through-holes 20g into the female screw holes 22b to fasten.
【課題】履板に付着する泥落としが容易に行なえる構成の作業機の無限軌道帯を提供する。【解決手段】左右一対のリンク板20,21を有するリンクを複数組備え、左右のリンク板20,21の両端を、隣接するリンクの左右のリンク板20,21の各端部にピン23およびブッシュ24により連結して無端のチェーン状に構成する。履板22の凸部22aに雌ねじ孔22bを設け、リンク板20,21に履板取付け用の貫通孔20gを設ける。貫通孔20gに挿通するボルト26を雌ねじ孔22bに螺合し締結することにより、リンク板20,21に履板22を取付ける。【選択図】図3
