Abstract
(EN)

PROBLEM TO BE SOLVED: To make it possible to mount a reinforcement rib along the center of a longitudinal lower part of a fitting section to thereby prevent uneven distribution of a load from a lower roller.

SOLUTION: A crawler crane 100 comprises: an affixation pin 23-1e for affixing an extension beam 23 to a fitting section 32a of a side frame 32; an affixation pin insertion hole 23-1g formed in the extension beam 23; an affixation pin fitting hole 32d formed in the fitting section; and a reinforcement rib 32e extended along a lower surface of a lower plate 32b of the fitting section 32a. The extension beam 23 is affixed to the fitting section 32a by inserting the affixation pin 23-1e into the affixation pin fitting hole 32d through the affixation pin insertion hole 23-1g. The reinforcement rib 32e is provided along an imaginary centerline 51 extending from the center of the opening of the fitting section 32a, and the affixation pin fitting hole 32d is provided at a position offset from the centerline 52 and not interfering with the reinforcement rib 32e.

【課題】補強リブを嵌め込み部の長手方向下部の中心に沿って設置可能とし、下部ローラの負荷荷重の偏りを抑える。
【解決手段】延長ビーム23をサイドフレーム32の嵌め込み部32aで固定する固定ピン23−1eと、延長ビーム23に形成された固定ピン挿通孔23−1gと、嵌め込み部に形成された固定ピン嵌入孔32dと、嵌め込み部32aの下板32bの下面に延設された補強リブ32eと、を備え、固定ピン挿通孔23−1gを介して固定ピン23−1eを固定ピン嵌入孔32dに挿入することによって延長ビーム23を嵌め込み部32aに固定するクローラクレーン100において、補強リブ32eを嵌め込み部32aの開口の中央から延びる仮想の中心線51に沿って設け、固定ピン嵌入孔32dを前記中心線52から外れ、補強リブ32eと干渉しない位置に配置した。
