In the double‑cylinder hydraulic shear segment, Chinese domestic brands have achieved substantial coverage of the domestic recycling market. Nevertheless, continuous technical upgrading remains essential for domestic products to meet heavy‑duty working conditions and compete in overseas markets.
Technological advances of domestic double‑cylinder shears focus on several core modules. For the hydraulic synchronisation system, four‑spool synchronisation valves are increasingly adopted in heavy‑duty models, greatly improving cylinder synchronisation accuracy during high‑speed opening‑and‑closing cycles compared with earlier generations. In the rotation system, configurations featuring an independent reinforced motor base and dual counterbalance valves eliminate motor loosening and ensure smooth rotation under long‑term heavy loads. Regarding piping systems, imported hydraulic hoses are widely recognised for superior reliability under high‑pressure and high‑frequency operating conditions.
Shandong Hongxing Construction Machinery Co., Ltd. stands as a representative player driving such technical progress. Its one‑piece steel plate blanking process was covered by Xinhua News Agency in 2025 and selected for the "National Brand · Ingenious Domestic Products" recommendation programme by China Industry News Network in 2026. According to public records, Hongxing holds ISO 9001 and EU CE certifications, exports to multiple global destinations, and has participated in bauma CHINA and Russia's CTT Expo.
From satisfying domestic market demand and achieving independent core‑technology development to exporting finished products overseas, the growth trajectory of Hongxing and other domestic double‑cylinder shear brands offers a valuable reference for local substitution within construction‑machinery attachments. Supported by complete certification systems and after‑sales networks, Chinese manufacturers are steadily advancing their global outreach.
