Product Overview
What The SLR333 Grade 80 Clevis Sling Hook Is
The SLR333 is an alternative clevis hook profile in the same Grade 80 programme. It carries the same testing regime as the rest of the range and every piece is supplied with a latch.
Shandong Shenli Rigging is a well known rigging brand in China with a modern management level and the ability to manufacture medium and high grade rigging. The product range includes more than 1000 varieties, among which the G80 connecting link, G80 safety hook, G80 shortening clutch and G80 Tawgk have been patented. Carl Stahl China has cooperated with SLR for over 13 years, which is what lets us offer a more competitive price and a reasonable minimum order quantity on this range.
Key Benefits
Why Buyers Choose This Product
Every Piece Proof Tested
Individual proof testing at 2.5 times the working load limit rather than batch sampling, so each item that ships has been loaded.
Crack Detection On 100 Percent
Magnaflux crack detection is applied to every piece, which catches forging defects that a visual check cannot see.
Fatigue Tested For Repeat Use
Fatigue testing at 1.5 times the working load limit for 20000 cycles proves the item survives daily service, not just one pull.
Reasonable Minimum Order Quantity
A long standing relationship with the manufacturer gives a competitive price and a workable minimum order quantity.
Application Scenarios
Where It Is Used And Who It Is For
Application Scenarios
- Grade 80 chain sling legs
- General site and workshop rigging
- Steel structure erection
- Plant maintenance
Who It Is For
- Chain sling assemblers and rigging houses
- Lifting equipment distributors
- Steel erectors and heavy contractors
- Project buyers sourcing complete sling sets
Problems It Solves
The Sourcing Problems This Product Removes
Rigging components arrive without traceable testing
Solution. Every piece is individually proof tested at 2.5 times the working load limit, magnaflux crack detected and marked with a batch number.
Minimum order quantities are unrealistic for a distributor
Solution. The long relationship with the manufacturer gives a reasonable minimum order quantity on this range.
Components from different sources do not match
Solution. The full Grade 80 programme comes from one manufacturer, so hooks, links, master links and chain assemble as a matched set.

Use Guide
How To Use The SLR333 Grade 80 Clevis Sling Hook Safely
- Confirm the component size matches the chain size in the sling assembly.
- Check the marking for the size, the grade, the working load limit and the batch number before use.
- Withdraw any component with a crack, a deformed body, a bent pin or a missing latch.
- Never mix Grade 80 components with lower grade fittings in the same assembly.
- Keep the assembly clean and inspect it at the interval required by local regulation.
