So as to increase the difficulty of operating personnel, it is unfavorable for job safety, increases operating risk.Simultaneously to the hoisting tool that insulate, to realize
So big loading is lifted, and larger difficulty is all brought in design and manufacture.
3rd, due to not being plane more than cross-arm head, during hot line job, the bending resistance of insulating materials, anti-twisting property are weaker, so
High requirement is proposed to raised position, it is impossible to which the requirement according to power failure operation is arbitrarily used like that, while to lift big loading bearing
Carry, insulating materials mechanical strength it is difficult to ensure that.
4th, the livewire work to lifting weight more than more than 5 tons, in operation process, the insulation standby fallen in anti-wire is protected
In shield measure, the insulating materials of such performance is there is presently no.
Analyze according to more than, need a kind of new lifting operational method of research and Work tool, to lift large-tonnage wire,
And realize being lifted and back-up protection integration, solve to change the work of the defect eliminations such as 500kV insulator chains in the case of big loading.Correlation is carried
The equipment of liter need to reach easy to operate, and Work tool installs simple, so as to improve the risk control of livewire work and work high above the ground, reduces
The labour intensity of operating personnel, strengthens the security of operation, and this case is given birth to therefrom.
