At present, the new design scheme of CR330E mining truck hydraulic system has been basically completed.
In order to ensure the design progress of CR330E mining truck, the Mining Equipment Department overcome several difficulties brought by the epidemic, actively communicated with suppliers, research institutes, process development departments and material supply departments to determine the details of purchased parts by email, call and other methods, held video conference to communicate with staffs at the test site and remotely solved the technical problems, formulated 48 technical specifications and agreements for CR330E special parts and general parts, completed the final version of component installation drawings of six hydraulic systems, and sorted out the installation details of the pipe fittings of four systems. At the same time, they also sorted out the design review data of CRRC mining truck, wrote two national invention patents and three utility model patents as the first inventor, and published two hydraulic papers and one journal paper on mining truck body structure.
