The Aerial Device Testing Instrument (ADTI) provides a cost-effective and technologically superior method to evaluate the structural integrity of man-lift, aerial, and transportation devices such as railroad tank tanks, bucket trucks, digger derricks, material handlers, fire truck apparatus, cranes, and more. AE testing listens for stress waves that are generated by the sudden movement of material in areas either under mechanical stress or where degradation (corrosion, crack growth) has occurred. Its intuitive, menu-driven interface and simplified graphics make ADTI capable of testing many different configurations of vehicles and devices.
