Yantai Gongma Construction Machinery Co., Ltd. is based in Yantai, Shandong. We are a direct manufacturer focused on the R&D, production and sales of hydraulic demolition attachments for excavators. Our products are exported to South Korea, Spain, Southeast Asia and other regions, serving equipment dealers, rental firms and demolition & recycling contractors.
Our factory owns complete production lines including cutting, CNC machining, welding, finishing, assembly and hydraulic testing. Full quality control is implemented from raw plate inspection to final machine testing. Core products are manufactured in-house instead of resold, so we can flexibly control specifications, quality standards and lead time.
We provide overseas clients with complete business and technical documents: company certificates, catalogues, spare parts manuals, hydraulic datasheets and CE documents for local registration. Both bulk orders of standard models and non-standard custom development are acceptable.
We are ready to meet you at Shanghai New International Expo Centre, 24–27 November 2026, Booth E4.689. Come to check our machines, watch demos and discuss pricing, lead time and long-term cooperation face to face.
