In the course of operation of chain conveyors emergency situations are possible. The reasons for this can be the intensity of the moving parts wear, increasing the pitch of the traction chains hinges, which leads to occurrence of shock loads in the traction body and failure of individual elements of the conveyor. Upon reaching a certain limiting increase in the pitch of the traction unit, further operation of the chain transmission cannot be possible due to significant decreasing the safety factor of the chains, violation of the ease of movement, or violation of the engagement of the chain joints with sprockets and cams of the intermediate drives. In the considered works dealing with studying the operating modes of plate conveyors, methods of solving the problem of distribution of loads between the master and slave drives in a multi-motor plate conveyor by means of a frequency-controlled electric drive are not considered.
