Chain

Durable grade 70 transport chain is available in lengths up 100 feet for load securement and towing. Grade 70 chain is available with or without a clevis end grab hook. Grade 30 proof coil chain is an economical option for light duty construction and agricultural applications. NOTE: Grade 70 and grade 30 chain is not approved for overhead lifting.

 

 

Chain Hardware

Cold shut links, quick link connectors and repair links are a fast, easy and inexpensive way to repair, join or extend chains and couplers in the field. Master links are an integral part of rigging and sling assemblies or can be used a standalone rigging accessory.

 

 

Clevis

Clevis rod ends are a U‑shaped fastener that allow for the quick and easy connection or removal of a variety of lifting and rigging components. Clevis ends come tapped and threaded for use with a threaded rod or as an untapped blank. Double clevis ends are popular for connecting chain ends to rings, end links, hooks or eye bolts.

 

 

Hoist Ring

Swivel Hoist Rings, or center-pull-hoist rings, feature a 180‑degree pivot and 360‑degree swivel to allow for lifting from nearly any direction. The ring absorbs any pitch, roll, or sway of an unbalanced load in order to complete the lift safely.

 

 

Hook

Grab hooks have a narrow throat to prevent chain from slipping. Slip hooks, or sling hooks, have a wider throat to allow chain to move to take up slack. Grab hooks and Slip hooks are available with clevis or eye sling attachments. Light duty snap hooks, or rigging carabineers, with a self‑closing latch are also available.

 

 

Lifting Eye Bolt

Machinery lifting eye bolts consist of a thread shank with an eye (loop or ring) at one end. The threaded shank is fully installed into a tapped hole in a piece of equipment or machinery for lifting. Lifting eye bolts come in plain pattern for zero degree vertical lifts or shouldered for angular lifts. DIN standard lifting eyes are also available.

 

 

Lifting Eye Nut

Machinery lifting eye nuts consist of a metal loop, or lifting eye, with a tapped hole on one side. Lifting eye nuts are installed on a threaded shank or post that protrudes from a piece of equipment or machinery. Lifting eye nuts come in plain pattern for zero degree vertical lifts or shouldered for angular lifts. DIN standard lifting eyes are also available.

 

 

Nut Eye Bolt

Nut eye bolts consist of a threaded shank or shaft with an eye at one end. The shank is inserted into an untapped hole and will protrude through the bottom of the hole. A nut secures the end of the shank and prevent the nut eye bolt from pulling back out. Nut eye bolts come in plain pattern for zero degree vertical lifts or shouldered for angular lifts.

 

 

Rod End

Rod ends, or swing bolts, are available as blanks that can be cut, drilled, tapped, threaded, or welded to make control arms, custom eye bolts, and other levers, or they can be machined to order to meet the requirements of your application.

 

 

Screw Eye Bolt

Screw eye bolts, or lag eye bolts, consist of a screw threaded shank with an eye at one end. The screw end is threaded into wood or a lag anchors. Screw eye bolts come in plain pattern for zero degree vertical lifts or shouldered for angular lifts.

 

 

Shackle

Anchor shackles, or bow shackles, have a rounded, O‑shaped bow to allow for side loading and sling-leg connections. Chain shackles, or D shackles, have a narrow bow for in‑line towing, hoisting and rigging applications. A pin is placed in the ears of the bow to secure slings, chains or rope in the shackle.

 

 

Swivel

Positioning swivels are created from two rigging end fittings held together by a threaded shank and nut. Positioning swivels are designed to allow movement prior to loading to align rigging hardware, but cannot swivel freely once the load has been applied. Eye x eye swivels and eye x jaw swivels are available.

 

 

Turnbuckle

A turnbuckle assembly is a common piece of rigging hardware that is used to reduce slack or adjust tension. Turnbuckles typically consist of three components, a body with a tapped hole on each side (one left-hand threaded and one right-hand threaded) and two end fittings. Common end fittings have a hook, jaw or eye at that end of a threaded shank. Alternately, a threaded shank called a stub end can be used.

Wire Rope Hardware

Wire rope clips can be used to form a load bearing loop at the end of a wire rope or cable. U‑bolt and double saddle, or fist grip, wire rope clips are available. Thimbles can also be used to help preserve the size and shape of the loop. Swage sleeves can also be used to create a loop or lag splice for cable ends.

 

 

Yoke End

Yoke ends (often confused with clevis ends) are a U‑shaped fastener that allow for the quick and easy connection or removal of a variety of lifting and rigging components. Yoke ends tend to be an off the shelf alternative to clevis ends, and come tapped and threaded for use with a threaded rod or as an untapped blank.

FREQUENTLY ASKED QUESTIONS
By Type

CHAIN

What is Grade 70 chain?

Grade 70 chain, sometimes referred to as "transport chain" is a high strength, heat treated, carbon steel chain often used to secure heavy loads. It is commonly used in agricultural, forestry, transportation, and industrial applications where strong, lightweight binding is desired. Grade 70 chain is not used for overhead lifting.

What is Grade 70 chain rated for?

Grade 70 chain, or G70 chain, is rated 700 Newton per square millimeter or 101,526 pounds of force per square inch per ASTM A413/A413M standard. As an example, 3/8 inch Grade 70 chain has a maximum working load limit of approximately 6,600 lbs.

CHAIN HARDWARE

How to repair chain:

A chain can be repaired using a repair link. Repair links are often installed and removed using a hammer and punch.

To install a repair link, slide the desired chain link into the open end of the repair link. Next, place the repair link against a solid surface and strike the opening of the link with a hammer to force it closed.

To uninstall a repair link, secure the link in a vice or similar tool to hold the link in place while being serviced. Position the working end of a punch or chisel in the crease of the repair link where the two previously open ends of the link have been closed together. Once properly positioned, firmly strike the protruding end of the chisel or punch with a hammer to force the ends of the repair link apart until it can be separated from the chain.

EYE BOLT

What is an eye bolt?

An eye bolt is a fastener designed with a threaded shaft with an unthreaded circular loop at one end. Eye bolts can be wire formed or forged. Wire formed eye bolts provide a small gap at one end of the loop whereas forged eye bolts provide a continuous unbroken loop. Eye bolts are available in a variety of sizes and are used as rigging points for securing, suspending, and lifting loads.

How to install an eye bolt:

Eye bolts are often installed in both tapped and untapped holes. Machinery lifting eye bolts are used for tapped holes whereas nut eye bolts are used for untapped holes.

To install a machinery lifting eye bolt into a tapped hole, simply insert the threaded end of the bolt into the hole, turning it clockwise to tighten. In some applications, the eye bolt may be designed with left‑handed threads, thus requiring it to be turned counterclockwise for tightening. Continue turning the eye bolt until no threads are visible and the eye bolt is securely tightened against the mating surface.

To install a nut eye bolt in an untapped hole, insert the threaded end of the eye bolt into the hole and push through until the threads of the eye bolt protruded out the opposite end of the hole. Next, thread a nut onto the threaded shaft of the eye bolt and tighten with the appropriately sized wrench.

HOOK

How to use a slip hook

Slip hooks, which have a wider throat than a grab hook, are often attached to chains or ratchet binders. They are commonly used to secure loads by hooking the opening over a rigging point such as a D‑Ring.

To use, simply pass the opening of the hook through the rigging point and pull so that the inner curve of the hook is pressed tightly against the rigging point. The closed end of the slip hook should be positioned in a manner that does not allow the hook to fall freely should clack in the chain or ratchet binder become present.

RIGGING

What is rigging hardware?

Rigging hardware is hardware designed to secure, lift, move, or suspend a load. This includes a variety of items such as Grade 70 chain, clevis shackles, turnbuckles, eye bolts, master links and more. G.L. Huyett's Aztec Lifting Hardware provides a wide range of rigging solutions for nearly any application.

How rigging works:

Rigging is a system of chains, ropes, or cables that often work in concert with clevises, shackles, turnbuckles, and other anchor points. This combination of hardware allows for the hoisting or securing of various loads ranging from boat sails to heavy construction materials.

SHACKLE

What is a clevis shackle?

Clevis shackle is a general term that encompasses anchor shackles or chain shackles. They are "U" shaped with a hole at each open tang allowing a pin to be inserted through. Some clevis shackle variations have a more prominent loop area closely resembling an "O" shape. Both "U" and "O" shape variations allow the shackle to support loads from various directions without creating excessive side load. Clevis shackles are commonly used with chains and master links in various industries that require rigging to secure, suspend, and lift loads.

How to use anchor shackles:

To use an anchor shackle, also known as a clevis shackle, remove the attached pin by either unscrewing it from the shackle or removing the cotter securing the pin. Next, insert the desired part, such as a chain link or a master link into the tangs of the shackle so that when the pin of the shackle is reinstalled, the part cannot be removed. Once the part is positioned appropriately, re‑install the pin.

TURNBUCKLE

What is a turnbuckle?

Turnbuckles are a fastener that is used to take up slack and apply tension for support or suspension, or to adjust the length of rope, cable, or tie rods. They consist of a metal frame called a body that is tapped with a left‑hand thread on one end, and a right‑hand thread on the other. Two end fittings (studs, eyes, hooks, or jaws or a combination of any two of these) are screwed into either end and attached to work pieces on either end before the body is rotated (turned) and both end fittings are drawn into the body simultaneously to apply tension.

How is a turnbuckle used?

Turnbuckles are used to adjust and take up slack in rigging applications. To use a turnbuckle, unscrew the connecting ends of the turnbuckle until only a few threads are left in the turnbuckle body. This will provide the maximum amount of take up. Next, connect the ends of the turnbuckle to the desired cable, chain, or anchor point. Once connected, turn the body of the turnbuckle to tighten. If the turnbuckle ends are rotating with the body, hold them in place so that they screw into the body equally. Continue to turn the turnbuckle body until the desired slack is removed.

WIRE ROPE HARDWARE

How is wire rope made?

Wire rope refers to wire cable 3/8 in diameter or larger. It is made by helically wrapping multiple strands of steel cable together around a steel or composite one.

What is wire rope used for?

Wire rope, or wire cable, is very common and used in a wide variety of industries to secure, lift, and suspend loads. Wire rope is comprised of multiple strands of wire wound together, allowing the rope to not immediately fail should one of the strands become compromised. Often this allows the task at hand to be completed before servicing the damaged area. Wire rope can be found on ski lifts, elevators, cranes, and much more.

How to crimp wire rope:

Wire rope is crimped using crimp sleeves, also called swage sleeves, along with special cable crimpers, or swage tools.

To crimp the wire rope, insert the rope into the sleeve, pulling the end completely through the sleeve. If creating a loop at the end of a cable run, loop the end of the cable rope back into the swage sleeve inserting it into the remaining empty space to create the loop. The size of the loop can be adjusted prior to crimping by pushing more or less rope through the sleeve. Once the desired loop size is achieved, use a swage tool or crimper to crimp the sleeve securely onto the cable.

How to cut wire rope:

For best results, wire rope should be cut using cable cutters that are appropriate for the size of wire rope being cut. Using standard side cutters can deform the end of the cable and cause it to fray. To cut, measure the amount of wire rope needed and insert the cable into the jaws of the cutter. Close the jaws of the cutter onto the wire rope until the jaws have cut cleanly through the rope.
