PROBLEM TO BE SOLVED: To reduce the weight of a lifting member and concurrently inhibit vibration of the lifting member during movement.SOLUTION: In a vibration control reinforcement structure of a gantry type loader, a lifting member 50 is formed by racks 51, each of which includes a gear surface 51a configured to engage with a gear surface 24a of a pinion 24 and formed on a side surface and extends vertically, rails 52, each of which is fixed to a rear surface of the rack 51 so as to extend vertically and slides along a first slide guide 23a; and reinforcement members 53. Each reinforcement member 53 is formed by a member which is fixed to a front surface of the rack 51, extends from a position at the same level with the first slide guide 23a to a position below an upper end of the rack 51 in a state where the lifting member 50 is moved to an uppermost position, and opens to the front side in an entire body when viewed in a vertical direction.SELECTED DRAWING: Figure 1
【課題】昇降部材を軽量化しつつ移動時における昇降部材の振動を抑制する。【解決手段】ピニオン24のギア面24aと係合するギア面51aが側面に形成された上下に延びるラック51と、ラック51の後面に上下に延びる状態で固定されて第1スライドガイド23aに沿って摺動するレール52と、補強部材53とで昇降部材50を構成するとともに、補強部材53を、ラック51の前面に固定されて昇降部材50が最も上方に移動した状態で第1スライドガイド23aと同じ高さ位置からラック51の上端よりも下方の位置まで延びるとともに、その上下全体にわたって前方に開口する部材で構成する。【選択図】図1
