    • PROBLEM TO BE SOLVED: To retract a front end side pendant in a desired folded state.SOLUTION: An operation support device 28 includes: a target angle storage section 30 for storing a first target angle for an interior angle between a boom and a jib and a second target angle of a smaller interior angle therebetween; a controller 33; and an instruction output section 34 for outputting an operation instruction in response to a command from the controller 33. The controller 33 causes output of an instruction for grounding the front end part of the jib at the first target angle when the tilting operation of a front attachment from a working state can be stably carried out at the first target angle. When the operation is unstable, the boom is lowered to form the first target angle on the ground after the front end of the jib is grounded at the second target angle, and then the controller 33 causes output of an instruction for tensioning a front end side pendant. This can always place the front attachment into a state in which the front end of the jib is grounded at the first target angle and the front end side pendant is tensioned. Then, the controller 33 causes output of an instruction for operation to make the boom and the jib horizontal.
    • 要解决的问题:将前端侧吊坠缩回到期望的折叠状态。解决方案:操作支撑装置28包括:目标角度存储部分30,用于存储在起重臂和起重臂之间的内角的第一目标角度;以及 其间具有较小内角的第二目标角; 控制器33; 以及用于响应于来自控制器33的命令输出操作指令的指令输出部分34.当前部的倾斜操作时,控制器33输出用于将起重臂的前端部分接地的指令处于第一目标角度 可以在第一目标角度下稳定地进行从工作状态的连接。 当操作不稳定时,在起重臂的前端以第二目标角度接地之后,起重臂下降以形成地面上的第一目标角度,然后控制器33输出用于张紧前端侧的指令 吊坠。 这可以始终将前附件置于其中前臂的前端在第一目标角度接地并且前端侧悬件被张紧的状态。 然后,控制器33使得操作指令的输出使起重臂和起重臂水平。

    • 【課題】 ペンダントを張る際にストラットに曲げ荷重が作用しないようにする。
      【解決手段】 後ストラット7は、先端部の前側に第1のリンク棒24の一端部を取り付け、第1のリンク棒24の他端部に、ブーム3トップの支持フレーム3aに取り付けた第2のリンク棒25を、連結ピン26で連結して関節部を形成する。 この関節部と支持フレーム3aとの間には、リンク板15と第3のリンク棒28の連結部をシリンダ14で屈伸させる形式のトグル機構を介装して、ストラット回動手段23を形成する。 後傾させた後ストラット7の先端部に基端側ペンダント8を接続した後は、シリンダ14によりリンク板15と第3のリンク棒28の連結部を伸展させ、第1と第2のリンク棒24と25の関節部を前に押すことで、後ストラット7の先端部を、第1のリンク棒24に沿う方向に引いて前方に回動させて、基端側ペンダント8を緊張させる。
