To ensure prevention of falling of a material transport body by preventing a contact member from sliding with respect to a perpendicular rod-like member when a falling prevention mechanism using the contact member which comes into contact with the perpendicular rod-like member is attached to an unloading device.SOLUTION: An unloading device 2 comprises: an adjustment box 10 lifted along a first guide pipe 50 circular in section; and a material transport body 40 connected to the adjustment box 10. The adjustment box 10 includes a lift body 20 that slides on the peripheral surface of the first guide pipe 50 to be lifted; and a falling prevention mechanism for preventing falling of the material transport body 40. The falling prevention mechanism includes an engaging part engaged with a lifting member of a lifting device, a key-shaped plate 13 pressed to the peripheral surface of the first guide pipe 50 when lifting of the lifting member is released, a coil spring 15 that tilts the key-shaped plate 13 and presses the key-shaped plate 13 to the peripheral surface of the first guide pipe 50, and a guiding member that guides the tilting of the key-shaped plate 13.SELECTED DRAWING: Figure 1

    【課題】垂直棒状部材と接触する接触部材を使用した落下防止機構を荷揚げ装置に取り付けるに際し、接触部材が垂直棒状部材に対して滑らないようにして、確実に資材運搬体の落下を防止できるようにする。【解決手段】断面が円形の第1案内パイプ50に沿って昇降する調整箱10と、調整箱10に連結された資材運搬体40とを備え、調整箱10は、第1案内パイプ50の周面上を滑って昇降する昇降体20と、資材運搬体40の落下を防止する落下防止機構とを備え、前記落下防止機構は、吊り上げ装置の吊り上げ部材に係合する係合部と、前記吊り上げ部材の吊り上げが解除されたときに、第1案内パイプ50の周面に押し付けられるかぎ状板13と、かぎ状板13を傾斜させて第1案内パイプ50の周面にかぎ状板13を押し付けるコイルバネ15と、かぎ状板13が傾斜するのを案内する案内部材とを備えた荷揚げ装置.2【選択図】図1
