I produced the patented chain for the first time the industry chain patent specification Shenzhen lifting chain, its production process and ordinary chain is very different. The patent chain nice, well structured, the overall performance is more excellent. If users need to send samples. Patented chain product image shown below: chen chain in order to ensure the accuracy of the correlation dimension and the tension of the chain using two correction and a worker pull Shenzhen lifting chain specifications, the maximum guarantee the overall quality of the chain. The first major correction is a correction size and type. Chain type styles: Style monocyclic typing: T8- specifications C; T8- specifications; G80; C G80; T8BB and other styles. I am currently typing is T8- General Specifications C and G80. You can also type in accordance with customer demand for the second correction is corrected chain tension and dimensions. Secondary Calibration aims to ensure the accuracy of the test chain pull and chain size, the test load two schools was 2.5 times the rated load. Such as 8mm chain of rated load is 2 tons, the test load is 2.5 × 2 = 5 tons. Two correction process if there is a chain off phenomenon Shenzhen lifting chain specifications need to re-take the ring, welding. This process requires a single ring dipped in fire. Monocyclic dip fire temperature of 1000 degrees. Rally detect single ring is cocking employment testing, 2.5 times the rated load of the tension value chain.
