JIANGTU quick hitch coupler has always been famous for its “good quality and durable use”. Many customers initially chose other brands because of the price, but “the cheaper option” had frequent issues, and then, most of them finally came back to JIANGTU.

After using JIANGTU, they realized the difference and praised the quality of JIANGTU!

Regarding the excavator quick hitch coupler, whether hydraulic or mechanical, the oil cylinder is always a significant component. If the cylinder is resistant to use, the quick hitch coupler will not have problem.

In this time, let me show you the quality and standards of the cylinders selected by JIANGTU.

Yantai Jiangtu Mechanical Equipment Company is a leading manufacturer of excavator attachments in China. All products’ quality is strictly under control from processing to delivery. By continuous innovation and improvement, the company has got ISO 9001, CE Certifications, and Technical Patents successively. Our products have been sold to widely domestic and overseas customers and long-term partnerships have been developed.

The difference between cylinder valve blocks

JIANGTU cylinder valve blocks are selected from high quality valve blocks that meet GB/T 8098 national standards, which are in the line with the high pressure and low flow resistance design.

Differences in oil seal performance

The JIANGTU cylinder oil seal is selected as a high-quality oil seal that meets the national standard of HG/T 2811. The material and structure determine its service life.

Cylinder piston rod chrome plating process

The chrome plating process of JIANGTU cylinder piston rod meets the GB/T 11379 national standard, and the thickness and hardness of chrome plating directly affect the wear resistance.

The coating thickness of JIANGTU cylinder piston rod is twice that of ordinary cylinder pistons.

Key factors and testing standards for cylinder quality

The precision processing of the JIANGTU cylinder is in accordance with the national GB/T 8713 standard, which is the key point to preventing leakage.

The JIANGTU cylinder valve block conforms to the design of high pressure resistance and low flow resistance. It adopts Korea made valve core and The U.S. made oil seal. The material and structure ensure the long service life of the cylinder. The high-precision machining of the cylinder is the key point to leakage prevention. Twice of the thickness and hardness of the chrome-plated piston rod of the ordinary cylinder brings high wear resistance. The higher quality oil cylinder, the more working performance of JIANGTU quick hitch coupler.

There are many types of JIANGTU quick hitch coupler, mainly including hydraulic wrist, swing quick change, double insurance/three insurance quick change, S connector, casting three insurance connector and mechanical connector, etc. We can also customize according to customer needs.
