To provide a crane and an adjustment method of the crane capable of adjusting a span between wheels arranged to be separated from one another in a traverse direction of the crane relatively easily.SOLUTION: A connection body 23 provided on one side of a wheel side or a leg structure side is arranged between a pair of holding walls 21a, 21b provided on the other side of the wheel side or the leg structure side. The connection body 23 is movably and externally fitted to a pin 22, both ends of which are substantially held by the pair of holding walls 21a, 21b. A plurality of liners 24 are sandwiched between the pair of holding walls 21a, 21b and the connection body 23. At least a part of the plurality of liners 24 arranged between one holding wall 21a and the connection body 23 are moved to between the other holding wall 21b and the connection body 23. A span between wheels is adjusted by changing a relative position of the connection body 23 with respect to the pair of holding walls 21a, 21b in the traverse direction X and by changing a relative position of the wheels with respect to the leg structure.SELECTED DRAWING: Figure 3
【課題】クレーンの横行方向に離間して配置されている車輪どうしのスパンを比較的容易に調整できるクレーンおよびその調整方法を提供する。【解決手段】車輪の側または脚構造体の側の一方側に設けた一対の保持壁21a、21bの間に、車輪の側または脚構造体の側の他方側に設けた連結体23を配置し、一対の保持壁21a、21bに両端近傍が保持されたピン22に連結体23を移動可能に外嵌めし、一対の保持壁21a、21bと連結体23との間に複数のライナ24を挟んだ構造とし、一方の保持壁21aと連結体23との間に配置している複数のライナ24の少なくとも一部を他方の保持壁21bと連結体23との間に移動させ、一対の保持壁21a、21bに対する連結体23の横行方向Xにおける相対位置を変更して、脚構造体に対する車輪の相対位置を変更することで、車輪どうしのスパンを調整する。【選択図】図3
