Human-saving is conveniently operated.
Further, the cross-arm frame and interior bar are laterally arranged, and constitute T-shaped structure.
Further, the hand crank is equipped with the sticking department of limitation hand crank rotation, can be limited by sticking department hand
Rotation, interior bar can be made to be fixed on the extension elongation of setting, and when needing to adjust extension elongation, sticking department can be unlocked,
Continue to adjust.
Compared with prior art, advantageous effect is：
1, by using the flexible temporary cross arm of this 10kV distribution line livewire work hand-rail types, temporary cross arm precisely can fast be adjusted
Height, replace 10kV single back lines on the iron cross arm activity duration foreshortened to by original 110 minutes<70 minutes.It will carry significantly
High working efficiency；
2, the insulation electric pole of the fixed temporary cross arm of operating personnel's installation, dismounting and adjusting is bundled in the repetitive operation of cement electric pole,
Also greatly reduce；
3, by the use of new tool, the operation difficulty of replacement process is reduced, ensure that the safety work space of operating personnel,
Reduce cross-arm operating risk on charged for replacement 10kV distribution lines；
4, the present apparatus uses the efficient kind of drive, staff to facilitate the height of adjustment cross-arm frame, and can adjust at any time.
