The analysis of the vibration system depending on the point of generation of the perturbation by frequency characteristics of a gearless lift’s direct suspension is made. It is shown that the behavior of the vibration system essentially depends on the place of perturbation: the cabin of a lift or the rope driving pulley. Depending on the point of generation of the perturbation the system of a direct gearless lift can have a “resonant” or an “inductive” character.

Introduction. The present invention generally relates to construction elements for erecting structures, and also to methods of erecting structures with the use of construction elements. Construction elements for erecting structures are conventionally flat elements, which are assembled at a site of construction for erecting a structure. Such flat constructions elements cannot be too wide because their transportation with the use of conventional transportation means is not possible. It is therefore necessary to use the construction elements with reduced width to allow their transportation, or to produce wide construction elements at the construction site. It is therefore believed that it would be advisable to improve existing construction elements and methods for erection of structures with their use. Result. The new technology of construction, based on the use of precast reinforced concrete large-sized spatial structures with variable geometry, allowing transportation without the special vehicles. After truck shipment and restore the geometry, structure is mounted to final position. As a result of the only one mounting stage, load bearing and (or) enclosure structure, permanent formwork of a monolithic slab floor are erected. The proposed technology is confirmed by the author’s priority (Patent № US 8,615,967 B1 / Dec. 31, 2013) Conclusions. Patent search report and the actual fact of the U.S. Patent allow us to draw a conclusion on feasibility and prospect of new technology.

In article the condition of a passenger transport complex of the Izhevsk city agglomeration is considered. It is noted that agglomeration includes a number of settlements of the neighboring regions. It imposes additional restrictions on development of all transport complex as it is necessary to agree in addition on the separate organizational economic problems relating to competences of local authorities. The main problems constraining development of a passenger transport complex from which are especially distinguished infrastructure, technical, administrative, and also tariff policy are shown. The package of measures on improvement of transport service of the population of city agglomeration is offered. Theoretically locates expected social-economic effekt.

Carry to the main advantages of galvanic ways of restoration: possibility of formation of a layer from several micrometers thick to 1-2 mm. metal or a combination of metals with the set properties, restoration "in the size", that is without the subsequent machining, simultaneous restoration of several surfaces and use of a small amount of electrolyte. A number of the devices allowing to provide the demanded conditions is developed for implementation of galvanomekhanichesky sedimentation of coverings. As the activating elements in these devices generally apply abrasive materials which working surface, in the course of work, "is salted", that is it is hammered with cutting products. It considerably reduces efficiency of activation of the cathode and uniformity of the received deposit in view of introduction in the formed layer the activating elements of products of activation. The offered device developed by Zakharov Yu.A. and Spitsyn I.A. it is deprived of such shortcoming in view of application of the activating elements in the form of leaders and the conducted abrasive rollers connected by a belt drive. For elimination of this lack of the existing devices by Zakharov Yu.A. and Spitsyn I.A. (patent No. 2503753) the device was developed for galvanomekhanichesky sedimentation of coverings on internal cylindrical surfaces of details. Difference of the offered device is that at sedimentation of an electrodeposit, the conducting and conducted rollers, being rolled on the activated cathode surface, rotate with various district speed because of their various diameter. As pulleys of leaders and the conducted rollers are connected by a belt drive, to the transfer relation no more than 0,8-0,9, on shaft of rollers there is various district force forcing the conducted rollers to slip rather cathodic surface. It provides better removal of the passivating film and continuous change of the surface of the activating roller contacting to the activated cathodic surface. Thus, the free surface of the activating roller is washed by a channel of electrolyte, being cleared of activation products that interferes with formation of so-called "zasalivaniye" of a wor1king surface of the activating elements (rollers).

The work is dedicated to the essence of the local budget and its revenues. Due to external economic pressures and crises in the world economy issue replenishment sources of tax revenues of local budgets has recently become even more relevant. Purpose - to propose measures to improve the profitability of local budgets. In this paper, using econometric methods to analyze different aspects of the replenishment of local revenues. Scope - law-making and tax administration. Possible perspectives - the conclusion of local budgets to self-sufficiency. The conclusion is that in a crisis to solve the problem of self-sufficiency of local budgets and the need to increase the proportion of the number of local taxes from federal.

Problems of culture of work, as a necessary element of forming a culture of safety, one of intensively developing directions of modern educational theory and practice. The work culture is seen as a complex subsystem of General culture of a person. The aim of the research is the analysis of the structure of forming a culture of safety. As the method is used theoretical analysis. There were two main blocks - obserwowac culture and professional culture of the engineer. Obserwowa culture develops ideas about the kinds of work and working methods, positive work attitudes, personal readiness to mastering the skills of General and professional. In the professional culture of the engineer were divided into three components: information, organizational and innovation. The availability of information culture of a specialist implies the possession of theoretical knowledge, practical skills and abilities. As part of the organizational component of professional culture tanned such components as the workplace organization, creation of safe and harmless working conditions. Innovative component provides support and development of creative potential of personality. Thanks to the work culture, people are not only able to meet their physical needs, but also to solve problems of self-development, self-improvement and self-esteem.
Keywords: culture of safety, the culture of work, obserwowa culture, professional culture, information culture, a culture of innovation.
analysis of the conditions of movement of vehicles on the roads has shown that special difficulties arise in the winter. This is due to the quality of the work of snowplows. One problem is the snow removal for road barriers. In line with this, and considered the possibility of the need to improve, creating a Russian-made snow plows. Based on the analysis of schemes snow removal from roads, structures working bodies with piles of snow plows, proposed a new design that allows for snow removal for road barriers, as well as the proposed use of a working body under a snowplow clearing patrol roads. At the expense of achieving the universality of cars increased their rate of use and, therefore, the payback period. The effectiveness of implementation of the new structure of the working body of the snowplow is achieved by reducing the amount of used equipment and passes undertaken during snow removal
