Changzhou Lian Hydraulic Equipment Co., Ltd. is located in Benniu Industrial Zone, Xinbei District, Changzhou City, Jiangsu Province. It was established in 1997 with a registered capital of 100 million yuan. The new factory covers an area of about 33,000 square meters, and the old factory covers an area of about 5,600 square meters. m, currently has 130 employees, including 8 intermediate and senior engineers and 16 assistant engineers.

Equipment Capabilities:It is well-equipped with high-end equipment such as Sunnen internal hole honing machine imported from the United States, 17m large CNC external cylindrical grinder, heavy CNC deep hole boring machine, vertical grinder (maximum honing internal hole 3m), CK61315X280/80 super-large heavy CNC machine tools and processing centers, ceramic spraying, laser cladding, etc., and is equipped with various inspection instruments and equipment: ultrasonic flaw detector, American roughness tester, German ultrasonic hardness tester, oil pollution detector, hydraulic test bench, etc.

Products:The company has taken advantage of its technology and equipment to develop non-standard extra-large hydraulic cylinders (it can manufacture hydraulic cylinders with a cylinder diameter of 1.8m and a stroke of 20m), large-scale pile-driving ship pile frame luffing cylinders, casting machine internally guided cylinders, externally guided cylinders, marine cylinders, offshore equipment cylinders, hydraulic cold drawing machines, hydraulic hoists for hydropower projects, metallurgical cylinders, multi-stage cylinders, ultra-high pressure cylinders, AGC servo cylinders and other types of engineering cylinders. It is a domestic professional internally guided cylinder, large hydraulic cylinder, large hydraulic cold drawing machine design and manufacturing enterprise, and its production and sales capabilities of similar products are firmly at the forefront of the industry.

Honors and qualifications:The company adheres to integrity and attaches great importance to quality, and has successively won honors such as the "Quality Integrity Five-Star Enterprise Certificate", "Jiangsu Famous Brand Enterprise Certificate", and "High-tech Enterprise Certificate", and has passed ISO9001 quality system certification, environmental management system certification, and occupational health system Certification; won 4 invention patents and more than 20 utility model patents.

Some achievements:Various types of hydraulic cylinders produced by our company are widely used in various industries at home and abroad. Our products are exported to the United States, Germany, Canada, etc. The hydraulic relays and hydraulic gate hoists produced by our company have been used in national projects such as the Three Gorges Project and the Longtan Hydropower Station. The 2000-ton hydraulic cold-drawn tube machine manufactured for Jiangsu Chengde Steel Pipe in November 2007 was an international first. In 2010, the company equipped the national large aircraft project with a 12,000-ton stretching main cylinder. The inner diameter of the super-large hydraulic cylinder for the high-speed rail project is 1.5m. The 2000-ton hydraulic cold-drawing unit produced in 2011 was exported to the United States. Its main cylinder has a cylinder diameter of 1250mm and a stroke of 14.8m. In 2012, we began to develop and manufacture internally guided hydraulic cylinders for casting machines, and successively provided internally guided hydraulic cylinders for Hunan Shengtong, Suzhou Mingheng, Kunshan Giant, Chongqing Southwest Aluminum and other companies, with good results. The 130m pile frame pile driving ship boom cylinder produced in 2019,Cylinder diameter 1.4m, stroke 15.2m, cylinder weight about 200 tonsThe hydraulic cylinder jointly developed by our company and Beijing University of TechnologyLaser cladding process for piston rod surface, has been successfully applied to internally guided cylinders and pile-driving ship cylinders.

Our service tenet is "survive by quality, develop by reputation, generate benefits by management, and serve customers by service".
