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.

In the article mounting a production system. The analysis of the structure of the mounting system of production is determined that an integral part of it is a collection of elements - technical control. This collection of elements is divided into two groups. The first belongs to the module technical design, which developed simultaneously with the mounting technology basic principles on the use and parameters of the control technology. The second one is implemented in the module production management and is related to metrological assurance (quality management) installation process. Describes the group of elements of technical control are interdependent, have diverse relationships with each other and with other elements of the system and Assembly production.

The problem of measuring the geometrical parameters of objects with curvilinear forms, is that for some material object it is necessary to determine the compliance of its controlled surfaces specified a priori (or a posteriori) geometric form. A common solution to this problem lies in the fact that in some coordinate system is set to reference the shape of a curved shape (circle, ellipse, parabola, hyperbola and other curves), it is necessary to determine whether the current point of the controlled object to a given curve.
