READ AND UNDERSTAND ALL IMPORTANT TERMS & WARNINGS BEFORE OPERATION OF ANY DURABILT DYVEX, Inc / DURABILT by DURBIN PRODUCT.
STATIC LOAD – The load resulting from a constantly applied force or load.
NEVER EXCEED ANY WORKING LOAD LIMIT (W.L.L.) of any DURABILT product, as you will be putting yourself and others at RISK which may result in SERIOUS INJURY or DEATH.
PROOF LOAD – The average force applied in the performance of a proof test; the average force to which a product may be subjected before deformation occurs.
PROOF TEST – A test applied to a product solely to determine non-conforming material or manufacturing defects.
MINIMUM BREAK STRENGTH (M.B.S.) – the maximum load or force applied to the product at which point the product fails to support the load, also known as MINIMUM BREAK LOAD.
SHOCK LOAD – A force that results from the rapid application of a force (such as impacting or jerking) or rapid movement of a static load. A shock load significantly adds to the static load.
DESIGN (SAFETY) FACTOR – Is a term denoting our product’s theoretical reserve capability, usually computed by dividing the Minimum Breaking Strength by the Working Load Limit. Generally these products have a minimum ratio of 3 to 1.
SPECIAL NOTE: The Durapullers (DP-T2, DP-T4, DP-T8) have a 2 to 1 ratio between the Capacity/Minimum Break Strength and the Working Load Limit.
Never exceed WORK LOAD LIMIT (W.L.L. – W.L. LIMIT, or S.W.L. – Safe Working Load) as identified on products or any Durabilt Media.
Failure to use these load binders properly may result in property damage, serious injury or death.
You must be familiar with STATE and FEDERAL regulations regarding the size and grade of chain being used as well as the number of tie-downs required for securing your load.
It is critical to follow D.O.T. (Department of Transportation) Federal Motor Safety regulations as directed in parts §392.9, §393.7(b), §393.100 and §393.102 through §393.136 (where applicable).
Never use handle extenders (cheater pipes). The use of handle extenders may overload the load binder or chain resulting in failure or deformation of the product.
Durabilt will not be responsible for any modification of our products. This will be at the end-users own risk.
Do not operate load binders while standing on the load. Always operate load binders while standing on the ground with secure footing.
Do not operate load binders on slick surfaces.
Use only the correct size and grade of chain with the proper load binder(s).
Lever binder Release: Note that there is stored energy in the secured chain which will be released through the handle causing it to “kick-back”. A steel bar should be placed under the handle for prying or use an opened hand in the same manner but be sure to keep body clear of handle path.
Always consider the safety of nearby workers as well as yourself when operating a load binder or any other product of Durabilt Dyvex,Inc.
DO NOT discard these warnings and instructions. Keep them and share them with others who may be using Durabilt load binders.
Routinely lubricate pivot and swivel points of lever binders as well as pawl part and screw threads of ratchet binders for reduction of friction and extension of product performance.
Remember that ALL strap assemblies or tie-down systems (i.e. winch binder) are only as strong as their weakest components including the point and method of attachment. Working Load requirements should be evaluated by the user before selecting appropriate hardware and strap assemblies. All worn products should be replaced immediately.
IMPORTANT: The WORKING LOAD LIMIT (W.L.L.) of these winch binders, if properly installed, is 5,000 pounds (LB).
WARNING: When tightening or loosening winches, always be sure to maintain a firm grip on the winch bar. NEVER release a winch bar without checking the pawl to ensure that it is fully engaged between the ratchet teeth. If you release the winch bar without the pawl being properly engaged, you could cause serious injury to yourself or to bystanders. Use only winch bars that are designed and marketed to use for Durabilt winch binders. Never use winch bars as “Cheater Bars” or “Handle Extenders” for lever or ratchet type binders. You should stay clear of the winch bar handle during its operation. During adverse weather conditions, these bars may tend to slip. Be sure to maintain good footing and hold bars firmly. The tip of the winch bar should be fully inserted through the front and back hole of the winch binder to prevent the winch bar from slipping out or over the winch bar tip. Winches should not be loaded in excess of their Working Load Limit (W.L.L.) or their components. (W.L.L.) Winches should never be used as lifting or pulling devices.
INSTALLATION WARNING: Webbing should be inserted through the slot of the mandrel with a minimum of 12″ of the webbing being inserted through the slot, and a minimum of two (2) complete wraps of the webbing should be placed around the winch mandrel.
CAUTION: Excessive wraps of webbing around the mandrel will reduce the Working Load Limit, WLL) of the winch.
Set screws on portable winch binders are designed to position the winch while the tie-down assembly is being tightened. The screws (2 each) should be snuq-tight only. Over tightening of the screws will cause the bracket-frame to bend and will weaken the winch causing failure, which may result in injury. Portable winches shall be removed when not in use.
A potential risk may occur when lifting or dragging loads with pulley block assemblies.
Failure to use pulley block systems properly will cause load to slip or fail. The result may be serious injury or death.
Instruct workers to stay alert and to wear correct safety gear in areas where loads are moved or supported with pulley block systems.
Do not use these products for overhead lifting.
Do not side load pulley blocks.
Do not exceed working load limit.
Tackle block systems should be rigged by a qualified person as defined by ANSI/ASME B.30.
• Do not exceed Working Load Limit.
• Do not pull cable across any other surface.
• Do not use this product as a choker.
• Do not use product as tow line or load binder.
• Do not support human cargo with this product.
• Do not use product if cable wire is rusted or kinked.
• See advising Working Load Limit (W.L.L.).
• Do not fail to check product for damaged or worn parts before each use and if necessary – replace.
DO NOT use a shackle without training.
ALWAYS Ask your employer for Shackle Safety use instructions.
ALWAYS comply with applicable Federal and local regulations.
Do Not use a shackle without a legible product identifier.
Do Not ride on shackle or load.
Do Not overload a shackle.
Do Not rig a shackle to a load improperly.
Do Not use a damaged or worn-out shackle.
Do Not use a shackle in extreme temperatures.
Do Not use a shackle in acidic conditions.
Shackle requirements depends on application.
Understand all governing laws and safety standards before use of shackles. Always know shackle load.
“Fittings shall be…of a minimum breaking strength equal to that of the sling…” -OSHA 1910.1840)(3)(1).
Do Not use a shackle without legible product identification.
Sling use regulation requires: “All employees shall be kept clear of loads about to be lifted and of suspended loads” – OSHA 1910.184 © (9).
Understand working load limits. Required strength depends on application. The rated load (WLL) of the shackle shall not be exceeded – ASME B30.26-1.9.1(b). If the shackle is to be side-loaded then the rated load shall be reduced in accordance with figure.
To avoid dropped loads and shackle damage. Avoid side loading shackle when possible. The screw pin shall be fully engaged, with the shoulder in contact with the shackle body. The screw pin shackle shall not be rigged in a manner that would cause the pin to unscrew.
Do Not use a damaged or worn out shackle.
missing or illegible manufacturer’s name or rated load.
indications of heat damage, weld spatter or arc strikes.
bent, twisted, distorted, stretched, elongated, cracked, or broken load bearing components.
a 5% reduction of the original or catalog dimension at any point around the body or pin.
The return to service should only be approved by a qualified person.
Do Not use a shackle in extreme temperatures. W.L.L. shall be reduced in accordance with the following chart when heated between 400°F and 750°F and should be permanently removed from service if heated above 750°F.
Lifting shackles shall not be used in alkaline or acidic conditions. Resulting metal embrittlement and accelerated corrosion can cause sudden failure.
Read and follow all use and safety information provided with any sling. Failure to do so may result in severe INJURY or DEATH due to sling failure and/or loss of load.
1. Sling Users Must Be Trained – All users must be trained in sling selection, use and inspection, cautions to personnel, environmental effects and rigging practices.
2. Inspect sling for damage – Inspect sling for damage regularly, if the sling is damaged, remove it from service.
3. Prevent Sling Damage – Protect sling from damage. ALWAYS protect slings in contact with edges, corners, protrusions, abrasive surfaces with materials of sufficient strength, thickness and construction to prevent damage.
4. Use Sling Safely – Do not exceed a sling’s rated capacity. Always consider the effect of sling angle and tension on the sling’s rated capacity.
5. Be Alert When Lifting Loads – Do not stand on, under or near a load with the sling under tension. All personnel should be alert to danger of falling and/or uncontrolled load, sling tension and the potential for snagging.
6. Sling Care & Storage – Maintain and store RoundSlings properly. Slings should be protected from mechanical, chemical and environmental damage.
To detect possible damage, perform a visual inspection and also feel along the entire length of the sling. Even damage that looks or feels “minor” can significantly degrade sling performance. If you have ANY doubts about the condition of a sling, DO NOT USE IT. Never attempt to repair a damaged sling (i.e. Tie knots in the webbing, etc).
When slings are not in use, they should be stored in a cool, dry and dark location. Slings should also be stored in an area free from environmental or mechanical sources of damage, such as: Weld spatter, splinters from grinding, machining, heat sources, UV or chemical exposure, etc.
Slings should be kept clean and free of dirt, grime and foreign materials. Mild soap and water can be used to clean slings, but be sure to let the sling dry completely before placing back in storage or use. Do not machine wash slings. Machine washing results in significant loss of sling strength.
If you want more information about Web Sling or RoundSling safety, contact WSTDA to obtain copies of the Synthetic Web Sling or RoundSling Safety Bulletin – a companion document to this labeling. (Web Sling & Tie-Down Safety Bulletins are also available).

A potential hazard exists when lifting or dragging heavy loads with tackle block assemblies.
Failure to design and use tackle block systems properly may cause a load to slip or fall – the result could be serious injury or death. A tackle block system should be rigged by a qualified person as defined by ANSI / ASME 8.30.
Instruct workers to keep hands and body away from block sheaves and swivels – and away from “pinch points” where rope touches block parts or loads.
Do not Side-Load Weld-on or Drill-on tackle blocks. Read, understand, and follow these instructions to select, use and maintain tackle block systems.
For maximum safety and efficiency, tackle block systems must be property designed, used, and maintained. You must understand the use of tackle block components in the system. These instructions provide this knowledge. Read them carefully and completely. Parts of these instructions must use technical words and detailed explanations. NOTE: If you do not understand all words, diagrams, and definitions – DO NOT TRY TO USE A TACKLE BLOCK SYSTEM!
Tackle Blocks must be regularly inspected, lubricated, and maintained for peak efficiency and extended usefulness. Their proper use and maintenance is equal in importance to other mechanical equipment. The frequency of inspection and lubrication is dependent upon the frequency and periods of use, environmental conditions, and the user’s good judgment.
Wear on pins or axles, rope grooves, side plates, bushings or bearings, and fittings.
Excessive wear may be a cause to replace parts or remove blocks from service.
Deformation in side plates, pins and axles, fitting attachment points, trunnions, etc.
Deformation can be caused by abusive service and/or overload and may be a cause to remove block from service.
Misalignment or wobble in sheaves.
Security of nuts, bolts and other locking methods, especially after reassembly following a tear down inspection.
Original securing method should be used, i.e. staking, set screw, cotter pin, cap screw.
Deformation of corrosion of hook and nut threads.
Surface condition and deformation of hook.
Welded side plates for weld corrosion or weld cracking.
Hook Latch for deformation, proper fit and operation.
The frequency of lubrication depend upon the frequency and period of product use as well as environmental conditions, which are contingent upon the user’s good judgment.
Assuming a state of normal product use, the following schedule is suggested when using lithium-based grease of a medium consistency: Lubricate Bronze Bushings (Not Self-Lubricated) every 8 hours of continuous operation or every 14 days of intermittent operation.
The Working Load Limit (W.L.L.) for blocks indicates the maximum load that should be exerted on the block and its connecting fitting. This total load value may be different from the weight being lifted or pulled by a hoisting or hauling system. It is necessary to determine the total load being imposed on each block in the system to properly determine the rated capacity block to be used.
There is no mechanical advantage to a single part load line system, so winch line pull is equal to 1,000 Lbs. or the weight being lifted.
A = 1,000 Lbs. X 1.84 = 1,840 Lbs.
B = 1,000 Lbs. X 0.84 = 840 Lbs.
The following is a calculation for determining the Total Load Value for a Mechanical Advantage System. As seen in the image below, there is a Hoisting System lifting 1,000 Lbs. using a traveling block. The Mechanical Advantage of the traveling block C is 2.00 because two (2) parts of the load line support the 1,000 Lbs. weight.
C = 500 Lbs. x 2.0 = 1,000 Lbs.
D = 500 Lbs. x 1.81 + 500 Lbs. = 1,405 Lbs.
C = 500 Lbs. x 0.52 = 260 Lbs.
C = 500 Lbs. x 1.29 = 645 Lbs.
Webbing straps must be protected when used across rough or sharp objects. All strap assemblies require inspection each time they are used. Straps that are cut, worn or otherwise damaged should not be used. Strap assemblies should never be tied into knots or allowed to become knotted. All straps are load control devices and should not be used for overhead lifting. Working load requirements should be evaluated by the user before selecting appropriate hardware & strap assemblies. All strap and binder assemblies or systems are only as strong as the weakest component, including the point of attachment. For other product warnings please see below and warnings on product labels.
All Durabilt ratchet and winch straps have sewn on labels to meet CHP Standards, CVSA Guidelines, North American Cargo Securement Standards, DOT Regulations, and WSTDA recommended standards. It is critical to follow D.O.T. (Department of Transportation) Federal Motor Safety Regulations as directed in parts §392.9, §393.7(b), §393.100 and §393.102 through §393.136 (where applicable).
Note: Please be aware of all current updates through 2010 and beyond.
