About Us
Zhuhai Tongjian Machinery Co., Ltd. originated from a well-known military enterprise in mainland China and relocated to Zhuhai in 1999. Since its establishment, the company has been dedicated to the development, production, marketing, and servicing of gear machinery.
Our company specializes in the production of the HK series planetary gear reducers, designed specifically for twin-shaft concrete mixers, artificial stone mixing, and pile stirring production. This series of reducers feature hardened gears, a compact structure, high load capacity, high efficiency, smooth operation, low noise, and outstanding performance.
The successful development of these products has transformed the market landscape. Previously, the industry relied heavily on expensive imported reducers, but our products now provide a high-quality and competitively priced alternative. Over the past decade, our gear reducers have gained widespread recognition and trust in the market. Currently, we offer a range of models suitable for concrete mixer outputs of 1.5m³, 2m³, 3m³, 4m³, and 6m³, along with related accessories.
Our company is supported by a team of professional technical experts with years of experience in gear design and manufacturing. Upholding the enterprise policy of “high-tech, high-quality, and high efficiency,” we are committed to further advancing the development of mixing equipment reducers and their accessories in the near future.
