3. The track ground connection resistance is less than 4Ω.

4. All explosion-proof electrical equipment does not have an explosion-proof certificate within the validity period issued by an explosion-proof inspection unit designated by the country.

5. Sparks and dangerous temperatures caused by mechanical friction collisions are dangerous.

6. There are broken wires on the surface of the wire rope.

7. The joints of the running track are not smooth and flat, and there are impact phenomena during the running of the wheels.
