Manufacturer: SmartTEH

The mobile rail unloader system is designed for bulk material handling from the bottom of the hopper without any need for an additional pit or other hopper. The specially designed and processed carrying belt is used on the Hopper wagon unloading system that does not allow product milling, grinding, or rubbing during the process.
The usual mobile conveyor productivity is relatively low; however, Smartteh’s Hopper wagon unloading system can reach productivity up to 800 m3/h. In comparison with other analogous solutions, it can exceed productivity several times.

  • With a help of specially designed belt type conveyors the bulk material is handled in a very gentle way;
  • Equipment is placed on a wheel chassis and is equipped with a stationary control cabinet or/and radio remote control; 
  • Four hydraulic cylinders provide adjusting (push down/lift up) the height of the equipment to the height of the railway;
  • With electric-powered drive, wheels provide machines entry under and exit from the wagon’s bottom;
  • The same table conveyors can be adjusted to wagon hatches with hydraulic drive.

  • Fewer product damages during the material transportation thanks to a specially designed belt;
  • Improved productivity;
  • Labour cost savings;
  • Savings on wagon renting;
  • Affreightment cost reduction;
  • Prevented air pollution problem;
  • Improved such important parameters as the unloading time, mobility, and fewer losses of material residuals during the transportation process;
  • Increased operational productivity of producers, transhipments, and consumers.
  • Using several mobile conveyor chains, it is possible to differentiate product automated movement within the ports and other material handling areas with high productivity, automation, and low labor resources.
