Intelligent solutions usually have one thing in common. They work on the basis of a simple principle and therefore they are more efficient, less prone to defects, and offer versatility. A description that fits RATAJ shaftless spiral conveyors down to a tee.

The essential element of RATAJ shaftless spiral conveyors is their shaftless spiral, which, with the help of a trapezoidal section, ensures that material is conveyed over the whole diameter of the conveyor. This special feature of shaftless spirals means large quantities of material can be conveyed, using the conveyor to full capacity with low revolutions and minimum power consumption.

Besides our high-quality technology, the most precious asset we can offer you is our know-how, i.e. how this technology is applied in practice. We keep ahead of the field by constantly implementing new developments, produced with help from our customers. All our customers, large and small, supply us with their information and experience concerning the operation of our shaftless spiral conveyors, which we then draw on as we find solutions to the conveying of new and hard-to-convey materials. You can ask us for free advice and consultations, or try out the opportunities available for conveying your material at the test conveyors we have set up on our premises.

A private company was founded by Stanislav Rataj to produce and supply technical products for the agricultural industry. Included in these suppliers were shaftless flexible screw conveyors of the type SL, initially used for the conveying of light loose materials.

By gradual development and the necessity also to transport materials with larger particle size, including abrasive and adhesive powders and granules, and due to the high demand, Ing. Stanislav Rataj formed a company solely for the production of shaftless screw conveyors. In addition to flexible screws, rigid conveyors type RL were produced and supplied to Czech market.
