Abstract
The issue of mechanization of hanging of long components of self-installing rock bolt (SIRB) type has been considered. The possibility of usage of slider-crank mechanism for these purposes has been proved. Linear dimensions of lever mechanism that meet the requirements defined by the applied motor and SIRB parameters have been determined on the ground of parametric synthesis. The performed force analysis has proved the application of fluid power drive.

Mechanization of hanging process of long components of self-installing rock bolt (SIRB) type can be performed with usage of modified slider-crank mechanism
Summary
Movement of duplicate parts in coincidence with manufacturing operations including painting or coating is used in the production of a variety of goods. Usage of suspended conveyors is more preferable for such purposes as it will combine transport and manufacturing operations [1]. The most complex part of the technological process is loading of the suspended conveyor that is being performed by hand at present. The pause between the following hanging operations is 60 seconds. A team of 5 workers is involved in a hanging operation. Hanging of each SIRB is performed by sequential operations: a) Removing of SIRB from a register; b) Moving to the conveyor for 2 m; c) Rotation of SIRB to 90°; d) Lifting of SIRB in high from 0,5 to 1,5 m; e) Hanging of SIRB on a conveyors hook. The first four actions are performed by a team of workers. The last action is performed by another worker situated directly near the conveyors hooks. The most labor intensive actions are rotation and lifting of SIRB
