Hey there! As a supplier of industrial electric chain hoists, I often get asked about the types of chains used in these nifty machines. So, I thought I'd take a bit of time to break it down for you.
First off, let's talk about the importance of the chain in an industrial electric chain hoist. The chain is like the heart and soul of the hoist. It's what actually does the heavy - lifting, quite literally. A good chain needs to be strong, durable, and able to handle all sorts of tough conditions in industrial settings.
Grade 80 Chains
One of the most common types of chains used in industrial electric chain hoists is the Grade 80 chain. These chains are made from high - strength alloy steel. The "Grade 80" refers to the minimum tensile strength of the chain, which is pretty impressive. It can handle a lot of weight without breaking or deforming easily.
Grade 80 chains are great for general - purpose lifting in industrial environments. They're used in a wide range of hoists, from smaller ones used in workshops to larger ones in factories. The reason they're so popular is that they offer a good balance between strength and cost. You get a high - quality chain that can lift heavy loads, but you don't have to break the bank to get it.
For example, if you're using an Snn - a High Speed Electric Chain Hoist, a Grade 80 chain is often the go - to choice. This hoist is designed for high - speed lifting, and the Grade 80 chain can handle the stress that comes with that.
Grade 100 Chains
Now, if you need even more strength, there's the Grade 100 chain. These chains are made from a special alloy that gives them an even higher tensile strength than Grade 80 chains. They're about 25% stronger, to be exact.
Grade 100 chains are used in situations where you need to lift extremely heavy loads or when space is limited. Since they're stronger, you can use a smaller - diameter chain to lift the same amount of weight as a larger Grade 80 chain. This can be really useful in tight spaces where you don't have room for a big, bulky chain.
Let's say you're using an Snn - c Electric Chain Hoist for a heavy - duty lifting job. A Grade 100 chain would be a great option. It can handle the high - stress lifting that this hoist might be used for, ensuring that the job gets done safely and efficiently.
Stainless Steel Chains
Not all industrial environments are the same. In some places, there's a lot of moisture, chemicals, or other corrosive substances. That's where stainless steel chains come in.
Stainless steel chains are highly resistant to corrosion. They're made from a special type of steel that contains chromium, which forms a protective layer on the surface of the chain. This layer prevents rust and other forms of corrosion from forming.
These chains are commonly used in food processing plants, chemical factories, and marine applications. In a food processing plant, for example, cleanliness and corrosion resistance are crucial. A stainless steel chain won't contaminate the food products, and it can withstand the cleaning agents and moisture that are present in the environment.
If you're using an Snn - b2 Electric Chain Hoist with Trolley in a corrosive environment, a stainless steel chain would be the best choice. It'll keep the hoist working smoothly for a long time, even in tough conditions.
Nickel - Plated Chains
Another option for chains in industrial electric chain hoists is nickel - plated chains. These chains are regular steel chains that have been coated with a layer of nickel. The nickel coating provides some corrosion resistance, although not as much as stainless steel.
Nickel - plated chains are often used in indoor industrial settings where there's a moderate risk of corrosion. They're also used when you want a chain that looks a bit nicer. The nickel plating gives the chain a shiny, clean appearance.
They're a good middle - ground option. If you don't need the extreme corrosion resistance of stainless steel but still want some protection, a nickel - plated chain could be the way to go.
Maintenance of Chains in Industrial Electric Chain Hoists
No matter which type of chain you choose for your industrial electric chain hoist, proper maintenance is key. You should regularly inspect the chain for any signs of wear, such as cracks, deformation, or excessive rust. If you notice any problems, it's important to replace the chain right away.
Lubrication is also important. A well - lubricated chain will run more smoothly and have a longer lifespan. Make sure to use the right type of lubricant for the chain material. For example, stainless steel chains may require a different lubricant than Grade 80 or Grade 100 chains.
Conclusion
So, there you have it! The main types of chains used in industrial electric chain hoists are Grade 80, Grade 100, stainless steel, and nickel - plated chains. Each type has its own unique properties and is suitable for different applications.
