An endless-track type mobile climbing vehicle containing a suspension apparatus, transducer manipulator and surface cleaning system to perform non-destructive examination of structures while traversing the structure in all positions. The invention is able to conform to large range of irregularities of the climbing surface while maintaining contact between the track and adhering members and uniformly distributing the climbing loads on the adhering members giving the system a high payload to weight ratio. The invention is moves the inspection transducer over the surface while maintaining correct alignment of the tool relative to the surface. The invention allows an operator to perform an inspection on structures that require cleaning or other preparation prior to inspection. The invention allows an operator to perform an inspection remotely.
