PROBLEM TO BE SOLVED: To provide a ladder lifting device which has high strength, achieves high level safety, and is smaller and more inexpensive.SOLUTION: A ladder lifting device 3 includes: a base 11 provided at an upper part of a fire truck 1; and a frame 12 to which a ladder 9 is detachably attached. The ladder lifting device 3 lifts the frame 12 from a storage position to a ladder attachment/detachment position. The ladder lifting device 3 includes: a link arm 13 which is provided so as to move on the base 11 in a fore and aft direction and swing on the base 11 in the fore and aft direction and comprises: a long arm 13a connected with the frame 12 and supporting the frame 12; and a short arm 13b connected with an intermediate part of the long arm 13a; a rear end support part 14 provided at a rear part of the base 11 and supporting the frame 12; and a male screw shaft 17 which extends in the fore and aft direction and is rotated by a driving part 15 to move a female screw block 16 connected with the short arm 13b.SELECTED DRAWING: Figure 1
【課題】強度および安全性が高く、より小型かつ廉価な梯子昇降装置を提供する。【解決手段】梯子昇降装置３は、消防自動車１の上部に設けられる基台１１と、梯子９が脱着可能な架台１２と、を備え、架台１２を収納位置から梯子脱着位置へ昇降させる。梯子昇降装置３は、基台１１上を前後へ移動可能、かつ基台１１上で前後へ揺動可能に設けられ、架台１２と連結して架台１２を支持する長尺アーム１３ａと、長尺アーム１３ａの中間部と連結する短尺アーム１３ｂと、で構成されるリンクアーム１３と、基台１１の後部に設けられ、架台１２を支持する後端支持部１４と、前後方向に伸びるシャフトを駆動部１５が回転することにより、短尺アーム１３ｂと連結する雌ネジブロック１６を移動させる雄ネジシャフト１７と、を備える。【選択図】図１
