The equipment we produce is primarily used to simplify and streamline the production processes of companies operating in the fields of mining, underground construction, and industrial manufacturing. The offered product portfolio is designed, developed, and produced internally at OSTROJ in Opava. In cases of highly specialized components, or in the areas of hardware and software, we collaborate with renowned producers.

Mining Machines and Automation

Comprehensive technologies and equipment for industrial operations with production lines in the fields of engineering, automotive, food industry, pharmaceuticals, and more.

More about category
Packaging Lines

Mechanical equipment and mechanization for packaging departments and production.

Special-Purpose Machines

Custom solutions and specific production often require specialized equipment, which we are happy to design for you.

Material Handling Equipment

Where human strength is insufficient, or there is a need to reduce handling costs, it is advisable to use handling techniques.

Vertical Conveyors

Material can be vertically transported to a height thanks to vertical conveyors.


Turntable conveyor allow for a change in the direction of material flow without changing the direction of the material itself.


For vertical material movement, conveyors can be supplemented with lift technology.

Turnable Transfers

To change the direction of material transport, we most commonly complement conveyors with this technology, a turntable.

Autonomous Transfer Carts

Complexly shaped materials are most commonly transported by autonomous transfer carts.

Conveyors Belt

Conveyors designed primarily for the transportation of rectangular prisms and other materials with longitudinal dimensions.

Chain Conveyors

Mechanization and machinery equipment for the transportation of bulky and heavy loads.

Conveyor Rollers

Technology for both light and demanding conditions, equipment for the transportation of non-standard shaped materials.

Belt Conveyors

Light and heavy operations require conveyor belts with increased durability and non-standard incline of the transport surface.

Modular Belt Conveyors

Mechanization and machine equipment for transporting materials, even in non-standard dimensions.

Assembly Lines

Mechanical equipment and mechanization for production segments are coordinated with both assembly lines operated by workers and robotic devices.


Mechanical equipment and mechanization for production segments that handle product packaging and shipping.

Automated Assembly Lines

Lines increase production capacity, reduce costs, and provide comprehensive solutions in various areas of various businesses.

Underground Constructions

Equipment and technology for the construction of road, railway, and metro tunnels.

More about category
Mobile Scaffolding

Technology enabling the creation of tunnel reinforcement and performing other auxiliary tasks during tunnel construction.

Mobile Formwork for Secondary Tunnel Lining

Mobile formwork is used to create the so-called geometric panelling of the tunnel.

Surface and Underground Mining

Equipment and technology for underground coal and ore mining and surface mining of non-metallic minerals.

More about category
Belt Conveyors

Technology for the transportation of granular materials with low economic and technological demands.


Bulk materials are transported by chain conveyors, which can have an inclination of up to 40°.

Chain Feeders

Technology for material transfer from conveyor systems, conveyors, and equipment.

Scraper Conveyors

The technology used in the extraction of coal and other bulk materials.

Mechanized Reinforcement

Ensuring safety during the extraction of abrasive materials such as coal, salt, or iron ore.
