The invention discloses a lightweight movable arm tower crane arm head hanging basket which comprises a main body, a lifting structure and an elevating structure. A lower handrail and an upper handrail are arranged on the inner wall of the main body; and the lower handrail is located below the upper handrail. According to the lightweight movable arm tower crane arm head hanging basket provided bythe invention, by arranging telescopic columns, connecting rods, fixing rings, rotating shafts, abutting blocks and shifting blocks, the main body can be entered after a door is opened; when the height of a guardrail needs to be adjusted, tension can be given to the connecting rods, and the connecting rods bear external tension to drive the telescopic columns to move, so that the multiple telescopic columns and the connecting rods move synchronously; and when the guardrail is lifted to the required height, the shifting blocks are shifted, the shifting blocks rotate to drive the abutting blocksrotatably connected with the shifting blocks to move, and the outer walls of the abutting blocks abut against grooves in the inner walls of the telescopic columns, so that the telescopic columns andthe connecting rods cannot move, the purpose of lifting the guardrail is achieved, and the working risk of workers is reduced.

    本发明公开了一种轻量化型动臂塔机臂头吊篮,包括主体、提拉结构、升降结构,所述主体的内壁设置有下栏杆与上栏杆,所述下栏杆位于上栏杆的下方。本发明通过设置伸缩柱、连杆、固定环、转轴、抵块与拨块,打开门就可进入主体的内部,当需要调节护栏的高度时,可给予连杆拉力,连杆受到外界拉力将带动伸缩柱移动,使得多个伸缩柱与连杆将同步移动;当抬升到需要的高度时,通过拨动拨块,拨块转动将带动与其转动连接的抵块移动,使抵块的外壁抵住伸缩柱的内壁凹槽,从而使伸缩柱与连杆无法移动,到达了抬升护栏的目的,降低了工作人员工作时的风险。
