The article describes the main principles of the movement around the circumference of the cranes circular steps. It is proved that the defining characteristics of the organization of the movement of the crane on the circle are the geometric parameters of the mutual reversal of the running wheels of the crane, not the observance of the reversal determines the transverse slippage of wheels of the crane, and the shape of the wheels depends only on the elastic longitudinal slide. The result of slides and slippage is firing the head of the rail with one hand and the loss of stability when moving the crane. Stability stability ensures the achievement of the precision targeting of the gripping device. These parameters are the main performance characteristics that should be valued in absolute terms should be minimal.

the article presents the study in the control of the geometric parameters of wheels of cranes circular steps. The options considered to determine the radii of the wheels by indirect methods, of which the most effective are those based on the construction of the measuring triangle at the open part of the forming. As the final results and proposals noted the following: both control provide almost ravnovesnye results definitions of the geometric parameters of the wheels; more universal is the way to control the radius of the wheel, using calipers and this method is recommended when addressing these and similar problems.

the Basic meaning of the content of the article is to reveal the formation of professional competence of students of higher education construction professions on the example of a business game. Business game "facade" is the functional-architectural meeting ambitious designers" was held under the second course in the discipline "Construction materials". The essence of this method is that students demonstrate certain production situation, which is characterized by conditions and actions of its participants. The task is to find the best modern methods of construction technologies. As a rule, the production situation in construction occur on the object, in our game object – the building of the Palace of culture, which was commissioned 10 years ago. During the operation of the building facade cladding in some places, damaged, cracks, and loose tiles. It was necessary to find the right solution for the replacement of the cladding material, to previously conduct a survey and identify the cause of the damage. For this group of students was divided into subgroups and each defined role. Each of the groups in the course of a game functioned, however, all must understand by simulating the situation and content of the actions of other groups. The problem was the following, as a preliminary survey of the damage to the facade of the object (performed measurements, photos, samples provided to the facing surfaces of the facade), it was necessary to establish the cause of the damage and propose the most optimal, effective and meets all the architectural, technological, technical and economic requirements methods of eliminating damage.the new enterprises, redistribution of investments in interests of the organization and development of new production on available floor spaces. The most important organizational economic targets of a diversification of management are presented by innovative activity of the industrial enterprise.
