A NEW PATENT GRANTED FOR ONHP INVENTION

Federal Institute of Industrial Property (FIPS) granted a patent for ONHP engineers’ invention – an extension ladder which has a minimal size in transportation position and minimum clearance in sliding joints, reducing dynamic loads in ladder structure elements in comparison with similar facilities.  

According to the designers, the advantages of patented ladder are higher reliability and safety, compactness in transportation position which is ensured by special structures of ladder sections and joints connecting the sections.  

Starting from 2019 it is already the third patent received by ONHP. Previous two patents were granted for “Screw scaffolds” ensuring convenient maintenance (visual inspection, painting, installation and other works) of internal surface of the spheres and “Recovery Method of Associated Gas” produced during oil extraction.
