To provide a ladder truck which promotes improvement of security to a gun shoot by comprising a bulletproof member to protect a person that tries to ascend and descend a ladder from the gun shoot.SOLUTION: The ladder truck comprises: a main ladder 3 which is pivotally attached to a vehicle body 1 in a freely raised manner; a secondary ladder 10 which is attached along the main ladder 3 in a freely slidable manner and can protrude in a tip side; a tip ladder 40 which is pivotably attached to a tip portion of the secondary ladder 10; and a plate-like bulletproof member 50 which is attached to the main ladder 3 in a freely raised manner. Operation force is reduced by providing a gas dumper 60 with a stopper which pushes the plate-like bulletproof member 50 in a standing direction.SELECTED DRAWING: Figure 1
【課題】梯子を昇降しようとする者を銃撃から守るための弾よけ部材を具備して、銃撃に対する安全性の向上を図る。【解決手段】車体１に起伏自在に枢着された主梯子３と、主梯子３に沿って摺動自在に取り付けられ、その先端側に突出可能な副梯子１０と、副梯子１０の先端部に枢着された先端梯子４０と、主梯子３に起伏自在に取り付けられた板状の弾よけ部材５０とを備える。板状の弾よけ部材５０を起立方向に付勢するストッパー付きガスダンパー６０を設けて操作力を軽減している。【選択図】図１
