Is 80 grade lifting chain high strength lifting chain?

RELEASE TIME :

2020-09-14

80 grade lifting chain is a kind of high strength lifting chain, high strength lifting chain is made of high strength manganese steel, and 80 grade lifting chain is also made of high strength manganese steel, so 80 grade lifting chain is a kind of high strength lifting chain.

80 grade lifting chain selection of foreign production line equipment, the chain after high frequency high temperature heat treatment process, by a variety of testing equipment strict supervision to ensure that is 80 grade lifting chain, 80 grade lifting chain all selection of high strength manganese steel made of, processing strictly in accordance with ISO3077, EN818, AS2321 product standards. The chain ensures 4 times the safety performance and 2.5 times the experimental load. 80 grade lifting chain surface can be polished and polished, black, dip paint, hanging plastic, electroplating process and other processing, in order to apply to large moisture, acid or alkali extreme regional environment, high strength lifting chain.

Usually lifting chain standard has: non-standard hoisting chain | national standard level 80 lifting chain, lifting chain | 80 lifting chain compared best but dare not say lifting chain type shall be counted as good in the chain.

Standard for complete abandonment of chain rigging:

Continuous application of autonomous electric welding should be avoided if the chain is broken.

Ring chain, lifting hook, inside or connecting parts deformation;

The mean diameter of the chain is reduced by 10%

Rashin in excess of 3% at all parts of the chain;

The lifting hook deformation exceeds 10%.

Analysis of Chinese chain industry quality work

Since 2003, Chinese chain industry still maintains rapid development speed. In 2004, under the guidance of the state macro-control policy, the Chinese chain industry changed the previous development thinking of heavy production and heavy market, adjusted and optimized the product structure, and gradually realized the transformation of economic growth mode. At the same time, Chinese chain industry has been developing high-tech content and high value-added new products, improving product quality and enhancing the competitiveness of Chinese chain industry in the international market as an important development strategy of enterprises. In recent years, in the chain drive association, chain drive standardization technical committee, the national chain quality supervision

The chain driving mechanism includes a chain

The utility model relates to a chain drive mechanism on a NC drilling machine used for blind hole processing in a perforating gun barrel. The utility model relates to a chain drive mechanism to solve the problem that the distance between the cutter head and the main sprocket on the NC drilling machine used for blind hole processing in a perforating gun barrel is long, and the single chain drive is easy to loosen and break the chain. The transmission motor drives the transmission pair gear to rotate through the transmission gear shaft and the transmission main gear, and the main sprocket shaft then rotates and drives the main sprocket to rotate. The chain drive and the centralized heating mechanism of the plastic bottle blowing machine, the chain drive mechanism comprises a chain and a number of transmission gears, the chain is fixed with a number of chain block components, including the chain block, each chain block

Force analysis and structure optimization of connecting link

The connecting link is the connecting part of the scraper chain of coal mine scraper conveyor, which plays an important role in the traction chain. Due to the special working conditions, traction chain link often occur fracture phenomenon, once the chain link is broken, the whole equipment is in a state of paralysis, seriously affecting the normal production of coal mine. Not only the economy suffered serious losses, but also the search for the broken chain and link are carried out on the side of the coal wall, there is a certain risk, and even cause personal accidents. The connecting link has a high breaking capacity, and a high reliability is required in the work. So the study of connecting link link change. Previous analyses of the butt link did not consider the effect of the cylindrical pin, and
