KOMAG develops concepts, design projects and technical documentation of the following equipment:
  • special gears for driving conveyors and rail-mounted vehicles,
  • flame-proof casings for electric equipment of rail-mounted vehicles,
  • small-size drilling rigs,
  • equipment for shaft sinking.

Horizontal Transport

R&D projects as regards machines and equipment for wheel, conveyor and rail transportation as well as designs for technology and machinery industry for materials displacement and transportation systems are realized at the Division of Horizontal Transportation.
We also realize projects for modernization of operating machines and equipment as well as designs of additional equipment for the existing machines.


We design the following machines and equipment:

  • Belt conveyors and flight-bar conveyors.
  • Self-propelled platforms, locomotives as well as electric and diesel drivetrains.
  • Bunkers and equipment for storage of loose materials.
  • Gravitational chutes and feed stream mechanical dividers.
  • Pumps for hydro-transportation and for water.
  • Cutter heads of mining machines (e.g. shearers, dredger cutters).
  • Lifting machines and mining-and-transportation machines.
  • Advanced drive systems.
Designs and documentations as well as modelling of production systems are realized with use of state-of-the-art information technologies and state-of-the-art CAD-3D designing methods.


We develop and provide the following:

  • Calculations of continuous transportation equipment.
  • Services as regards technical consultancy on horizontal transportation and drive systems.
