Zhenjiang Zhono Heavy Machinery Co., Ltd. is a professional manufacturer specialized in the design and manufacture of high-tech enterprises of various types of couplings, transmission basic parts. Located in the scenic, cultural blend of the Three Kingdoms city of Zhenjiang, the company's existing staff of 86 people, including 2 senior engineers, mechanical design and manufacturing, heat treatment, welding and other types of more than 20 professionals, advanced process and reasonable detection means complete. I actively introduce and absorb advanced technology and equipment, research and innovation, Strict product quality, and operate in strict accordance with the ISO9000 quality certification system standard mode. Universal coupling, gear coupling, flexible couplings, rigid couplings, flexible couplings and other dozens of series, thousands of specifications coupling in the company's leading products, widely used in metallurgy , mines, lifting and transport, petroleum, chemical, paper, pharmaceutical, textile, printing and dyeing, ships, locomotives, pipe equipment, slitting, Kaiping, straightening a variety of industries, our products strictly according to the standard production, production of couplings smooth transmission reliable transfer torque, angular displacement compensation capacity, long life, legacy coupling ideal replacement products. Our products are produced by the standard GSL long retractable gear coupling due to the number of famous foreign companies OEM, design parameters and quality of service life are exactly the same as the import is the ideal replacement products, but also for users manufacturing special specifications, special purpose couplings. I produced a variety of standard and non-standard couplings, as well as all kinds of non-standard equipment, accessories, and well received by users. For many coupling enterprises coupling imported localization provides strong support for technology and equipment, won the majority of users praise.
