Rosen Innovation AB (formerly Mark Trade Innovation) is a Swedish family-owned company founded in 1981. We specialize in the development and manufacturing of polyurethane lifting blocks and aircraft chocks for the aviation industry. Since 1990, we've designed lightweight, high-friction aircraft chocks for large aircraft, solving the common problems associated with traditional heavy rubber chocks.
In collaboration with ramp staff at Landvetter Airport, Gothenburg, our chocks underwent rigorous testing before approval. Third-party testing by AFRY confirmed excellent friction performance on both wet and dry concrete/asphalt, matching or surpassing heavier competitor products.
Our chocks are ergonomically designed, requiring just 0.5 kN of pulling force for removal—compared to 3.1 kN in some conventional models—significantly improving working conditions for ramp operators, where mechanical equipment is often needed due to excessive resistance.
We supply international airports, airlines, ground handling agents, FBOs, helicopter operators, and more.
Our GREENLINE series is made from a new polyurethane compound using water as the blowing agent and excludes all REACH-listed substances. The chocks are 100% recyclable, and we operate a closed-loop recycling program: customers can return used chocks to us for reuse in new production. We use 90% recycled material and 10% virgin polyurethane, making us the only manufacturer offering this sustainable solution.
