Lifting and Rigging Chain - Grade 70, 80, and 100 Alloy Steel Chain

You will get efficient and thoughtful service from Lieying Group.

Lifting and rigging chain has been one of the most popular rigging products on the market for many years, mainly due to its strength, durability, and ease of use. All our alloy steel rigging and lifting chain is heat treated to offer industry leading load capacity and durability. Some steel rigging chains are approved for overhead lifting, while others are not, so it is important to always know what type of lifting chain your specific rigging application requires. There are 3 major grades of alloy steel chain that are approved for overhead lifting:

1. Grade 80 Alloy Steel Chain
2. Grade 100 Alloy Steel Chain
3. Grade 120 Alloy Steel Chain

These special grades of alloy steel chain are ideal for overhead lifting due to their high strength and abrasion resistance, as well as their ability to stretch up to 20% before breaking when subjected to overloading. It is important to note however, that any amount of stretch during a lift is unacceptable. This is an essential safety feature that differentiates alloy steel chain approved for use in lifting slings from, for example, the type of steel chain you would find in a hoist.

Here at Tri-State Rigging equipment we specialize in fabricating lifting slings and assemblies using overhead lifting approved chain, but we can also provide you with bulk alloy steel rigging chain.

In addition to g80, g100, and g120 alloy steel rigging chain we also offer grade 70 transport chain, commonly used in the trucking and transportation industry. We can provide you with any rigging product on the market, so if you cannot find what you are looking for, or if you don&#;t know exactly what you need, call or our sales team to speak with a rigging product specialist.

Grade 80 Lifting Chain

Grade 80 rigging chain, commonly referred to as grade 8, grade 800, g80, or g800 rigging chain, is the first grade of chain approved for overhead lifting and for use in lifting slings. G80 alloy steel chain is heat-treated to give it the proper amount of strength to perform overhead lifts. This also gives grade 80 alloy lifting chain superb abrasion resistance. G80 chain has dominated the lifting and rigging industry in the past and can be used for any rigging application requiring chain grades of 30-80. Additionally, grade 80 lifting chain can be used in environments with temperatures up to 400° F with no reduction in working load limit and in environments with temperatures up to ° F with a reduction in working load limit both during and after the lift. To identify grade 80 sling and lifting chain, look for an 8, 80, or 800 embossed on the chain.

Grade 100 Lifting Chain

Grade 100 lifting chain is very similar to grade 80 alloy steel chain, but it has a 25% higher working load limit than the same size of g80 alloy steel chain. This allows riggers to use lifting chain more ergonomically, using a smaller sized chain at the same working load limit. Just like g80 lifting chain, g100 lifting chain is used mainly as a component in lifting slings but can also be used in any application that requires grade 30-100 alloy steel chain. The use of grade 100 rigging chain has gained a lot of popularity recently. Riggers like using g100 rigging chain because of its industry leading strength and abrasion resistance. Additionally, grade 100 lifting chain can be used in environments with temperatures up to 400° F with no reduction in working load limit and in environments with temperatures up to ° F with a reduction in working load limit both during and after the lift. To identify grade 100 sling and lifting chain, look for a 10, 100, or embossed on the chain.

Grade 120 Lifting Chain

Grade 120 alloy steel lifting chain is the newest innovation in rigging and lifting chain. With 20% higher strength than grade 100 and 50% higher strength than grade 80, grade 120 lifting chain is the strongest chain available in the lifting and rigging industry. G120 lifting and rigging chain is seen as a specialty grade of alloy steel chain by most in the rigging industry, but its popularity is on the rise. Grade 120 lifting chain is perfect for rigging applications in rugged environments where the size and weight of the chain is a concern. Using g120 rigging chain allows riggers to use a smaller chain size for their application without sacrificing the working load limit. To identify grade 120 alloy steel lifting chain, look for a 12, 120, or embossed on the chain.

Grade 70 Transportation Chain

Grade 70 chain, commonly referred to as transport chain or trucker&#;s chain is constructed using heat-treated carbon steel. G70 chain is the rigging chain of choice in the trucking and transportation industry and is used as tie-downs on over-the-road trailers. Grade 70 steel rigging chain is not approved for overhead lifting and is never to be used for such. This special grade of chain meets all requirements set by the California Highway Patrol and Department of Transportation. In addition to transportation and trucking applications, g70 transport chain can be used in towing, logging, oil rigs, and safety chain applications. Grade 70 steel rigging chain has a gold chromate finish. This not only adds much needed corrosion resistance to handle the rigors of highway use, but it also makes it easy to identify and double check you are using the right steel rigging chain for your specific rigging application.

Lifting and Rigging Chain Best Practices

No matter what type of chain you decide to use, the chain, as well as the rigger must follow the standards put forth by the National Association of Chain Manufacturers (NACM):

• Loads that are lifted with chain are never to be transported or suspended over people.
• All chains are to be periodically inspected for:
  • Cracks
  • Gouges
  • Wear
  • Stretch
  • Nicks
  • Suitability
• A reduction of alloy steel chain performance can occur when exposed to excessive temperatures or chemically active environments including acids, and corrosive liquids or fumes.
• Before using rigging and lifting chain outside the recommended temperature range, always contact the chain&#;s manufacturer to properly reduce the working load limit.
• All chain is to be removed from service if the thickness on any part of the chain falls below the listed minimum value.
• All alloy chain assemblies are to be rated at the working load limit of the weakest component.

When exploring chain come alongs versus chain hoists, we&#;re comparing two devices made to pull and lift heavy loads. Both devices operate manually and help make handling and towing loads manageable. The benefits of manual hoists are that they&#;re portable and cost-efficient. Hoist devices are primarily used in the industrial and agricultural industry but are also DIY friendly for small business owners. The difference between chain come alongs versus chain hoists lies in how each tool operates to lift a load. A come along, or lever hoist, lifts a load using a lever and can move items horizontally or vertically. A chain hoist, also referred to as chain blocks, lifts a load through pulling a chain and can only move objects vertically. In short, come alongs can manage heftier loads than standard chain hoists. It&#;s important to examine the mechanisms of each device to understand how they differ and why they suit different lifting jobs. Explore chain come alongs versus chain hoists.

What Is a Chain Come Along?

A chain come along, or lever hoist, is a hand-operated device with similar features to a chain hoist. A come along is an advanced pulley system with chains and gears operated through a lever. A come along device functions with a friction disk attached to a ratchet wheel with a double pawl system. Pawls, the lever that connects with the teeth of a ratchet, prevents the wheel from turning in the wrong direction when pulling the lever.

How Does a Chain Come Along Work?

The main advantage of operating a come along is that it can be operated with one hand. A chain hoist requires both hands to pull on the chain, whereas a come along only requires pulling a lever. A standard come along contains two hooks at the top and bottom of the device. The hooks are swiveling or sling hooks for easy access. The bottom hook is where you attach the come along to the load, and connects to the chain located through the shaft of the tool. The top hook of a come along requires anchoring before mobilizing a load.

The two most significant features of a come along is the directional switch and the retaining pawl. The directional switch is on the body of the come along. The directional switch is how you operate the device to lift, lower, or spool a load. The directional switch features are up, down, and neutral selection for raising, lowering, or spooling loads. The retaining pawl is also on the body of the come along. The retaining pawl is above the grip ring of a come along. Pressing the retaining pawl releases the grip ring to adjust the chain or place it in a neutral position as needed.

How Is a Chain Come Along Used?

A chain come along is primarily used for pulling loads in multiple industries. The advantage of using a come along over a chain hoist is being able to manipulate the direction of pulling the load, whereas a chain hoist only permits lifting a load up or down. Below are some of the most common uses for a chain come along.

• Moving pipes
• Moving machinery
• Winching cars
• Pulling fence fabric
• Pulling tree stumps
• Removing barbed wire

What Is a Chain Hoist?

A chain hoist, or chain block, is a pulley system made to lift loads vertically. Chain blocks double the pulling force when lifting a load and are sold with varying lifting capacities. A chain block has multiple gears and two primary chains. These two chains are the hand chain and the load chain. The hand chain is what a user pulls on to operate a chain hoist. The load chain attaches the chain hoist to the load itself. The manual operation of a chain hoist allows minimal labor in pulling the hand chain to lift heavy loads.

How Does a Chain Hoist Work?

Inside a chain hoist device, there are multiple gears that multiply the force applied by pulling the hand chain. When the hand chain is pulled on a chain block, the energy turns the main cog through a driver shaft. After converting energy through the driver shaft, the friction plate and internal gears apply force to the primary sprocket that powers the load chain. The main cog operates on the driver shaft that&#;s secured between a small gear and a pair of larger gears. The pair of larger gears increase the power required to rotate the driver shaft. The larger gears have smaller gears attached to them and connect to an even larger gear that transfers power to the primary sprocket connected to the load chain.

The hand chain webs through the slots on the main cog. The internal gears activate and begin to turn when pulling the hand chain. When the main cog turns, the driveshaft presses downward until the cog pressed against the friction plate of the ratchet wheel. The internal gear, friction plate, and ratchet wheel simultaneously move to operate the lifting process. While pulling on the hand chain, a lever or catch mobilizes through the teeth of the ratchet wheel. The lever or catch prevents the main cog from moving backward when lifting a load.

How Is a Chain Hoist Used?

When you pull the hand chain on a chain hoist, multiple internal gears move in synchrony to magnify the force and vertically lift a load. Chain hoists are useful for managing a load that originally requires multiple people to lift. The chain hoist is a versatile device because if you attach an object to the hook of a chain hoist, it only requires one person to operate the hand chain for lifting the load. Below are the most common uses for a chain hoist.

• Lifting a car engine
• Lifting a car transmission
• Lifting loads on a conveyor belt
• Lifting loads on construction sites
• Lifting I-beams in a building foundation
• Lifting H-beams in a building foundation

Devices like chain come alongs and hoists simplify lifting loads that typically require the strength of multiple people.
