The invention relates to a synthetic insulator simple ladder. The synthetic insulator simple ladder is characterized by comprising a simple ladder grapple, the lower end of the simple ladder grapple is fixedly connected with a simple ladder hoisting and adjustable device, and a chain at the lower end of the simple ladder hoisting and adjustable device is fixedly connected with a main rod of the simple ladder. The synthetic insulator simple ladder is used for such operation as replacement of a synthetic insulator and a suspension wire clamp and the like by work personnel from an iron tower cross arm to a lead wire. The synthetic insulator simple ladder helps line maintenance personnel to inspect and replace the synthetic insulator and the suspension wire clamp, does not cause damage to the synthetic insulator due to trampling, scratching and bumping of the synthetic insulator, reduces the number of tools needed by line inspection personnel for replacing the synthetic insulator, facilitates inspection and maintenance of the synthetic insulator, the wire clamp, the lead wire and other accessories by the work personnel on a tower, accords with the principles of science, practicality and economic benefits, reduces damage caused to the synthetic insulator and guarantees safe and reliable operation of a line.
