All lifting straps manufactured or provided by NANJING DAHUA meet or exceed all OSHA regulations as well as WSTDA standards.

Triangle-Choker - Type 1 Synthetic Web Sling

- Do not attempt to use sling above rated lifting capacity.
- When selecting a sling,it is very important to consider the angles at which the sling will be used.
- Slings are subject to cutting when ifting items with sharp egeds.In this case,always use protective sleeves
- Do not use a damaged sling,and se only if trained.
- Do not tie knots in sling webbing as strength is greatly reduced.
- Never drag a sling beneth from a load which is resting on it.
- Chemical active environments can affect the strength of slings
- Inspect slings weekly or more frequently depending on the sling use conditions.
- Always strore slings in a cool,dry and dark place to extend the working lift.
- Always read and understand the operating instructions before use.
- Failure to comply with this warning may result in serious load damageand death or injury.

When using flat woven webbing slings always:

• Store and handle belt slings correctly.

• Inspect belt slings and accessories before use and before placing into storage.

• Follow safe slinging practices, as given overleaf.

• Position the bight for choke lift at 120° (natural angle).

• Position the sling so that the load is uniformly spread over its width and protect the sling from sharp edges.

• Apply the correct mode factor for the slinging arrangement.

When using flat woven webbing slings never:

• Attempt to shorten, knot or tie belt slings.

• Expose belt slings to direct heat or flames.

• Use belt slings at temperatures above 80°C or below 0°C without consulting the supplier.

• Expose belt slings to chemicals without consulting the supplier.

• Shock load belt slings.

• Use belt slings which are cut or which have loose or damaged stitching

Selecting the Correct Sling

Belt slings are available in a range of materials and sizes in single leg and endless sling forms. Select the slings to

be used and plan the lift taking the following into account:

Material

Polyester is resistant to moderate strength acids but is damaged by alkalis; polyamide (Nylon) is virtually immune to

alkalis but is damaged by acids; and polypropylene is little affected by acids or alkalis but is damaged by some

solvents, tars and paints.

Capacity

The sling must be both long enough and strong enough for the load and the slinging method. Apply the mode factor

for the slinging method. For use at temperatures exceeding 80°C or below 0°C refer to the suppliers instructions. If

the slings are used in multi-leg arrangement the angle formed between the legs should not be less than 30° or

greater than 90°. If abrasion, heat generated by friction or cutting from edges or corners are likely, select a sling

fitted with protective sleeves and/or use suitable packing.

Storing and Handling Belt Slings

Never return wet, damaged or contaminated slings to storage. They should be cleaned with clear water and dried

naturally. Never force dry belt slings. Store belt slings hung from non-rusting pegs which allow the free circulation of

air. The storage area should be dry, clean, free of any contaminates and shaded from direct sunlight. Do not alter,

modify or repair a belt sling but refer such matters to a Competent Person.

NOTE: The material from which the sling is manufactured may be identified by the colour of the label or printing on

the label: Polyester = Blue, Polyamide (Nylon) = Green, Polypropylene = Brown and the sling may also be dyed with

a colour code to indicate SWL.

Using Belt Slings Safely

Do not attempt lifting operations unless you understand the use of the equipment, the slinging procedures and the

mode factors to be applied. Do not use defective slings or accessories. Check the correct engagement with fittings

and appliances, ensure smooth radii are formed, do not twist or cross slings and do not overcrowd fittings. Position

the sling so that the load is uniformly spread over its width. Position the bight for a choke lift at the natural (120°)

angle to prevent friction being generated. Ensure that stitching is in the standing part of the sling away from hooks

and other fittings. Take the load steadily and avoid shock loads. Do not leave suspended loads unattended. In an

emergency cordon off the area.

In-service Inspection, Maintenance and Replacement 

Inspect slings each day before use, looking for:

• Missing or unreadable ID tag
• Melted, charred or weld-splattered areas
• Acid or alkali burns
• Holes, tears, cuts, snags or embedded particles
• Broken or worn stitching
• Excessive abrasive wear or elongation
• Knots or brittle areas
• Broken, corroded, pitted distorted fittings

Do not use worn or damaged slings or attachments. Discard or repair them. Use damaged slings only after they are repaired, reconditioned, and proof tested by the sling manufacturer or a qualified person. Keep certificates of proof test.

Maintenance requirements are minimal. Belt slings may be cleaned with clear water. Remember weak chemical

solutions will become increasingly stronger by evaporation. Regularly inspect belt slings and, in the event of the

following defects, refer the sling to a Competent Person for thorough examination: illegible markings; damaged,

chaffed or cut webbing; damaged or loose stitching; heat damage; burns; chemical damage; solar degradation;

damaged or deformed end fittings.
