Depending on the safe reliability, the flexible rotation, the long life and other distinctive advantages, HY series rolling bearing blocks with "Tong" word plate becomes the national standard of HY block in China.

Hot rolled steel wheel (150 mm-1,800 mm) is made of the single board through the single rolling. Depending on the high accuracy, the big load, the wear resistance, the good strength and other advantages, it becomes the renewal product of the cast iron and steel wheel. In 2007, it won the first prize of national scientific and technological progress.

In 2010, JDB embedded sliding bearing block (16-1000 ton) won the Innovation Prize of China International Patent & Brand Expo depending on the high pressure resistance, the strong impact resistance, the sediment resistance, the ageing resistant, the water lubrication with free of excessively heated axle, the wear resistance, the shock absorption and so on.

"TOPLIFT" heavy duty block have been designed by American Tongli Company. Its mechanical properties are accorded with EU standard, and it is made of special advanced alloy steel with severe heat treatment and first-class surface treatment process, so as to get CE product certification.

"TOPLIFT" wide-body shackles have been developed by the design center for three years. It can be able to forge 25T-1000T wide-body shackles and has CCS, ABS, DNV product test certification.

The above products fill the gap in China and stand the peak of the technological innovation.

It got CCS works approval in 2010 and got ISO 9001:2008 quality management system certification in 2016.

Over three decades, Tongli has got dozens of patents and led the innovation and development in Chinese hoisting block industry depending on the persistence and innovation as well as making science and technology as the guide.

Over three decades, Tongli has completed many large lifting tasks safely and effectively, including three gorges project, port of Shanghai, Yantai dockyard, Beijing-Shenzhen highway, Yangtze Hukou bridge, Yuanbaoshan power plant, Hegang mining, capital iron and steel company and hundreds of national key projects. The products not only are the lead in the domestic market, but also are exported to America, German, Mexico, Brazil, Chile, and Singapore, and are favored by the foreign businessmen with high reputation.

Over three decades, Tongli has provided a high quality product and created engineering models without any worries for domestic and foreign customers.

Core advantage

1. Center for professional creation

Professional research center to fill the gap.

Hebei Tongli pulley Co., Ltd. is a appointed factory in China's heavy transport machinery industry, with the research center of Hebei lifting sling in China, forging subsidiaries, and testing centers, which is a group enterprise integrating product development and design, forging, processing and testing. The professional trochlear hanger Research Center, led by the experts of the domestic authority trochlear lifting experts, has obtained dozens of innovative technologies:

In 1998, HY series rolling bearing pulley filled the domestic blank;

2006 hot rolled steel wheel made the national patent;

In 2007, the mining trochley got the gold medal of the fair; the public company has now obtained the CCS China Classification Society approval certificate .

i. The rotation is flexible, the speed efficiency is increased by 100%

ⅱ. Closed one-time flow of oil, reduce the construction of oil trouble.

ⅲ. Greatly reduce friction resistance, increase the service life of more than 3 times.

ⅳ. The unique spring expansion ring makes the bearing position to prevent lateral movement.

2.  Strict inspection procedure

Perfect the test equipment to ensure the quality of the components

Hebei Tongli pulley Co., Ltd. has a complete set of testing and testing equipment, including automatic multi-element metal analyzer, magnetic powder and ultrasonic flaw detector, impact test machine, universal tension test machine and so on, to ensure that the material and quality of the various parts of the trochlear and other hangers fully meet or exceed the customer's needs.
