To provide a crane which can improve anti-vibration effect in a short side direction of a hanger without increasing a size of a trolley, and a crane rope stretching method.SOLUTION: When hanging a rope R around an upper sheave Sb via a lower sheave Sa from a trolley 2, the rope is stretched in the state that a first portion 6 extending toward the lower sheave Sa from the trolley 2 is substantially vertical when seen in a direction parallel to a short side direction x that is an extension direction of a short side, and is stretched in the state that a second portion 7 extending toward the upper sheave Sb from the lower sheave Sa is inclined with respect to the first portion 6, and the rope is stretched in the state that the second portion 7 is substantially vertical when seen in a direction parallel to a long side direction y that is an extension direction of a long side, and is stretched in the state that the first portion 6 is inclined with respect to the second portion 7.SELECTED DRAWING: Figure 5
【課題】トロリを大型化することなく吊具の短辺方向における振止効果を向上できるクレーンおよびクレーンのロープ張設方法を提供する。【解決手段】トロリ2から下方シーブSaを経由して上方シーブSbにロープRを掛け回す際に、短辺の延長方向である短辺方向xと平行となる方向に見通したときにトロリ2から下方シーブSaに向かって延びる第一部分6が略鉛直となる状態に張設するとともに下方シーブSaから上方シーブSbに向かって延びる第二部分7が第一部分6に対して傾く状態に張設して、長辺の延長方向である長辺方向yと平行となる方向に見通したときに第二部分7が略鉛直となる状態に張設するとともに第一部分6が第二部分7に対して傾く状態に張設する。【選択図】図5
