Overhead conveyor Chain Drives are available in two general types, the caterpillar drive and the sprocket drive, and is one of the most important components for overhead conveyor system.

It depends on the material, normally for the material 5140(40Cr),the average tensile strehgth of X678 chain is 410KN.

Usually we use two materail for our pitch 101.60 drop forged chain.For 20MnCr5 material, the Ultimate tensile strength is 110KNFor 42CrMo4 material, the Ultimate tensile strength is 210KN

Following to government environmental protection law, Zmie foundry now focus on installing anti-pollution equipment and upgrading relevant production technique , and has recovered partial production .

Yes, China government is trying best efforts to reduce pollution by investigating to foundries personally to check by themselves. CC600 are made by casting , which involves several stages of pollution .

Silicon sol lost wax casting and shell casting are recommended for cast process.Silicon sol lost wax casting is a typical investment casting process for stainless steel casting chain, it's with smooth surface and with high quality.Shell casting is the most common casting process for Mass ordinary casting chain, like our catingchain 907E-51 and 4103, combination casting chain C55 and C188, CC600 ch...

Yes, Zmie have provided CC600 chain in material PA6 before.

We have standard external diameter of trolley wheel, like φ120,φ80,φ82 and φ60.And we also can offer the trolley wheel of custom-made dimensions to fit cutomer special application, like φ125, φ135...

As Zmie focus on producing conveyor components, starting the earliest, can supply whole range of conveyor components , even including track itself, such as straight track, horizontal track 90 degree, 4x4 free carrier-front trolley,middle trolley and rear trolley .

Usually,our quality control procedures include the following:1,Raw material analysis and check steel suppliers certificate.2,Regular dimensional checking every stage3,Pitch tolerance checking every 10FT.4,Hardness checking are carried out 5 parts by 1 furnace time. We also follow others requirement if customer asking 点击打开链接 ...

ZMIE enclosed track chain packing mode can follow customer’s requirement.There are two kinds of packing way are popular, one is packed into case directly, which is more economical, and another is 20FT in one box, 40boxes one pallet.

No, ZMIE’s drop forged chain can be used in not only overhead conveyor like paint conveyor system, car assembly system, but also floor conveyor like car wash system, suger mill conveyor.

This year China government pay more and special attention to the environmental protection, for some critical factors, especial casting and electroplating industry...the control measures are much stricter than before.many casting foundry and electroplating workshops are being stopped now.the old method of casting “lost wax casting” has been completely banned. now the allowed method of casting is sh...

Yes, the products all produced by Zmie.

Drop forged rivetless chain for Power Only and Power and Free conveyors, has a high strength to weight ratio, is extremely flexible in both horizontal and vertical planes, is easy to assemble without tools, and remains intact while in service with minimum maintenance.

The maximum rated chain pull losd is 750 pounds for 8" enclosed track chain.The chain ultimate tensile strength exceeds 10,000 pounds.

Yes, Zmie is producing in large quantity and various category of enclosed track chains, which is also called flex chain, 7 ton and 8 inch chains . They are widely used in light duty overhead conveyor system, being designed to be flexible in every direction, easily to be dismantled.

Zmie's standard "B" attachment is the most commonly used to support a load bar from a pair of trolleys.The "B" attachment is a steel forging with a threaded stud at the end. The attachment fits between the two trolleys.

The material and heat treatment is the key to improve the strength of drop forged chain. To reach the best strength and wear resistance, we choose 20CrMnTi with case hardened. For example drop forged chain 14218, the break load can reach to 29Ton.

Yes, Zmie's riveltless chain 698 can reach 160,000lbs with material 42CrMo.

Drop Forged Conveyor Chains are widely used in bulk material handling of products such as grain, coal and ash.Also known as drop forged scraper chains. They are typically fitted with flights or special attachments.The chain links themselves are forged from specially selected alloy steel and then precision machined to close tolerances.As China chain manufacturer we produce ranging from 10160,10160R...

Drop forged link chain often weld with attachment on working. zmie weld many kinds of scraper for forged chain. Such as square bar-flight, flat bar-flight, paddle-flight, U-flight, OO-flight,OO-flight with filler plates and return cup flight.And also able to manufacture special flights that are suitable for almost any design.

Yes, Zmie has been producing self-locking forged X458 chain and attachment links for over 10 years, you will find lots of specials are being produced besides those of standard X348, X458, X678 drop forged chains and overhead trolleys.

"H" attachment is the most widely used type of trolley attachment and is suitable for almost any type of hook and rack.

点击打开链接ZMIE normal materials of Forged Chain: 40Cr ( SAE5140), 42CrMo (SAE4140), 20CrMnTi.The chain with material 40Cr ( SAE5140), 42CrMo (SAE4140) the strength is better,The chain with material 20CrMnTi the wear resistance is better.Select materials according to your application.

Besides cast chain CC600, F801,MC33, and 462 stainless steel cast chain, workshop also successfully developed cast wire sheave,cast pulleys like Mag 3 wheel and Mag 5 wheel and cast sprockets.
