The utility model has the advantage of:
1. terraced body adopts stretching structure, has effectively reduced the appearance and size of ladder, shrinks volume small and exquisite in carrying process, 70~90cm only, convenient safe distance of remaining valid with the charged position of high-tension apparatus, in addition, has also saved memory space greatly, carry light and handy convenience, when not using, can leave in the boot of general car, during use, directly moving on-the-spot expansion deformable to is double ladder, yi shaped ladder, more than yi shaped ladder is ascended a height and highly can be reached 4m, folding and unfolding is rapid, uses at any time;
2. terraced body adopts high strength epoxy resin to make, and insulation is lightweight, has guaranteed the safety in utilization of ladder in high field;
3. the trip gear of positioning lock locking mechanism is hidden under cross-lining, in assurance work, can not touch by mistake, reasonable in design;
4. the upper and lower end of extension ladder is equipped with hook, convenient construction personnel hang over tool box on ladder, insulating glove frame and tool box are provided, the problem that while having avoided work high above the ground, operation tool is deposited nowhere, also guarantee the safety of insulating glove, avoided the get an electric shock and die generation of accident of operating personnel.
The utility model is simple in structure, uses, easy to carry, can rush towards fast scene, and folding and unfolding is rapid, safe and reliable, has thoroughly stopped common step ladder under the high electric field environment of transformer station the get an electric shock and die problem of accident of operating personnel easily occurs.
