Title
(EN) WORKING MACHINE WITH CRAWLER UNIT
(ZH) 带履带牵引装置的施工机械
Abstract
(EN) The present invention makes it possible to mount a reinforcement rib along the center of the longitudinal lower part of a fitting section to thereby prevent uneven distribution of a load from a lowerroller. This crawler crane 100 is provided with: an affixation pin 23-1e for affixing an extension beam 23 at the fitting section 32a of a side frame 32; an affixation pin insertion hole 23-1g formedin the extension beam 23; an affixation pin fitting hole 32d formed in the fitting section; and a reinforcement rib 32e extended along the lower surface of the lower plate 32b of the fitting section 32a, and the crawler crane 100 is configured such that 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 throughthe 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 affixationpin fitting hole 32d is provided at a position offset from the centerline 52 and not interfering with the reinforcement rib 32e.
(ZH) 本发明能够将加强筋沿嵌入部的长度方向下部的中心设置,从而抑制下部辊的外施荷载的不均。履带式起重机(100)具备:固定销(23‑1e),将延长梁(23)固定于侧架(32)的嵌入部(32a);固定销插通孔(23‑1g),形成于延长梁(23);固定销嵌入孔(32d),形成于嵌入部;及加强筋(32e),延伸设置于嵌入部(32a)的下板(32b)的下表面,通过将固定销(23‑1e)经由固定销插通孔(23‑1g)插入于固定销嵌入孔(32d),将延长梁(23)固定于嵌入部(32a),在所述履带式起重机(100)中,将加强筋(32e)沿从嵌入部(32a)的开口中央延伸的假想的中心线(51)设置,将固定销嵌入孔(32d)配置于从所述中心线(52)偏移且不与加强筋(32e)发生干扰的位置。
