Sling Identification

Identifying Nylon Slings

There are 5 common styles of basic nylon slings.

Typically, nylon slings are ordered as SINGLE PLY or DOUBLE (2) PLY.

This is indicated on the tag & easily identified by viewing the sling

Identifying Nylon Bridle Slings

Nylon Bridle Slings will have a capacity & serial number tag affixed.

Bridle slings include overhead lift rated hardware.

Typically a grade 80 or grade 100 master ring or sub-assembly at the top and hooks at the end of the legs.

It is possible that there will not be any hardware at the ends of the legs as shackles or rated attachments may be used.

Nylon bridle slings are typically used in 2 leg, 3 leg or 4 leg arrangements.

All information is typically indicated on the tag attached to the bridle.

However, that tag will not indicate the ring size, hook capacity or grade at each leg.

In some instances, loads to be lifted have uneven pick points.

These pick points must be accounted for in order to evenly distribute the weight during the lift.

This is easily accomplished on any alloy chain sling by adding shortening clutches or shortening hooks (adjusters).

The 'A' prefix (or suffix) indicates 'Adjusters'

Identify which style in your notations: clutch or hook style & manufacturer of the part

This method is used across North America although some companies show the 'A' at the end of the descriptor

ADOS or DOSA Regardless..... we need to know & we prefer the prefix style...

Grade 80 & Grade 100 Components

Only Grade 80 & Grade 100 chain are legal for overhead lifting.

Identification is marked on all grade 80 & grade 100 products.

Grade 80

Look for 8 or 80 or 800.

It will be cast onto rings, hooks & connecting links.

It will be embossed or stamped onto chain links.

Typically orange, red or yellow in color.

Grade 100

Look for 10 or 100.

It will be cast onto rings, hooks & connecting links.

It will be embossed or stamped onto chain links.

Typically blue in color.

NOTICE: You may find grade 80 / 100 components together on a chain sling.

Make sure that the assembly is rated @ grade 80 NOT grade 100 capacity

Components

Please do not reference part numbers when requesting replacement hooks or components.

We will need to know who the manufacturer of the specific hook is.

Different manufacturers have different bearing point measures.

Mis-matched hooks create excessive stress on 1 leg of the sling.

This may lead to a sling failure resulting in property damage, equipment damage, personal injury, a fatality or a combination of all.
