Alexandrovsk Machine-Building Plant is one of the oldest plants in Ural starting its history since 1802. 
The rockloaders are intended for loading of the rock separated from the solid into the means of transportation when making direct inclined slopes from top downward down dip with inclination angle not exceeding 180.
