Carried out theoretical studies have shown: vibration exciters with the coaxial - linear alternating-current motor and electromagnetic dc-drives have advantages before analogs; it is recommended to use alternating-current for low-power systems two, and for powerful three phase windings with inverse; for martempering operating modes probably use of a magnetic suspension. It is developed main principles of build-up of guidance systems by these drive units. Use of an asynchronous linearly - impulse drive unit of a disconnector improves starting traction bar and diminishs a transient period. Main principles of not destroying echo - inspection method of quality of stilts that allows to test it on presence of imperfections are opened and approximately to estimate strengthening performances of concrete, and also static and dynamic methods of definition of a load-carrying capacity of stilts. The executed analysis of inspection methods of quality and definition of a load-carrying capacity has shown, that numbered directions of examinations are perspectiv and demand the further more detailed elaboration.
