Road construction machine parts are engineered using high-strength alloy steel, ductile iron, and wear-resistant alloys. Heat treatment processes including normalizing and quenching increase hardness to 50–64 Rockwell C, extending service life. Hydraulic components are rated for up to 360 bar operating pressure, utilizing multilayer composite seals for reliable performance under demanding conditions. Bearings and bushings are manufactured with dimensional accuracy below 0.003 millimeters, enhancing motion efficiency and reducing friction. Metallic surfaces are protected with ceramic or electroless nickel coatings applied at 30–55 microns thickness.
The weight of road construction machine parts ranges from 2 kilograms for auxiliary components to over 900 kilograms for primary assemblies. Mechanical joints employ grade 12.9 bolts and hardened bushings to withstand high dynamic loads. Rubber and polyurethane parts are produced with hardness values of 60–90 Shore A, providing vibration absorption along with tear and compression resistance. Advanced CAD and FEA software is applied for design and analysis, ensuring that critical components deliver more than 15000 operational hours in construction and mining projects.
