Abstract: A condition detecting method and device for a surface insulation layer of an elevator traction belt. The condition detecting method includes: positioning a detecting component adjacent to the surface insulation layer of the elevator traction belt; moving the elevator traction belt relative to the detecting component, so that the detecting component scans the surface insulation layer of the elevator traction belt; applying static electricity to the detecting component through a static electricity generation component; detecting the reaction of the elevator traction belt to the static electricity; and identifying the condition of the surface insulation layer of the elevator traction belt according to the detected reaction of the elevator traction belt to the static electricity.
