To provide a crane truck which enables hook storage work to be efficiently carried out.SOLUTION: The crane truck comprises: a winch device that includes a boom head provided in a tip part of a boom and a wire having a hook fitted to the tip end, and raises or lowers the hook by performing a winding operation and a delivering operation of the wire; a controller 50 that causes the winch device to perform the winding operation or the delivering operation in accordance with an operation of an operation device 19; a tension detector 48 that detects the tension of the wire; and a boom position determination unit 52 that determines whether or not the boom exists at a prescribed position. The controller 50 causes the winch device to stop the winding operation irrespective of the operation of the operation device 19 when the tension detector 48 detects that the tension of the wire becomes equal to or higher than a prescribed value when making the winch device perform the winding operation in a state where the boom position determination unit 52 determines that the boom is at the prescribed position.SELECTED DRAWING: Figure 3

    【課題】フックの格納作業を適切かつ効率よく行うことができるクレーン車を提供する。【解決手段】ブームの先端部に設けられたブームヘッドと、先端部にフックが取り付けられたワイヤを備え、ワイヤの巻取作動および繰出作動を行うことで、フックを上昇または下降させるウインチ装置と、操作装置19の操作に応じてウインチ装置に巻取作動または繰出作動をさせるコントローラ50と、ワイヤの張力を検出する張力検出器48と、ブームが所定位置に存在するか否かを判断するブーム位置判断部52と、を備え、コントローラ50は、ブーム位置判断部52においてブームが所定位置に存在すると判断されている状態でウインチ装置に巻取作動をさせているときに、張力検出器48によってワイヤの張力が所定値以上になったことが検出されると、操作装置19による操作に関わらずウインチ装置の巻取作動を停止させる。【選択図】図3
