The present invention discloses at least one lifting device, which is configured to lift or drop at least one load bearing mechanism. The lifting device includes a power driving mechanism and multiple lifting mechanisms connecting to the power driving mechanism. The multiple lifting mechanisms march the load bearing mechanism at least from a first height location to a second height location in a rolling manner under a function of a driving force provided by the power driving mechanism. The present invention further discloses an ultrasonic inspection system using the lifting device. |
