Grade 100 Single-Leg Chain Sling, Self-Locking Hook Both Ends — Type SSLSL

Grade 100 single-leg chain sling made up with a self-locking hook at each end. The chain and every fitting are Grade 100 alloy steel, quenched and tempered, and matched in size so that no component is the weak point.

What SSLSL means

Chain sling make-ups are named by a letter code read from the top down: S = single leg; SL = self-locking hook; SL = self-locking hook. So an SSLSL sling is a single leg sling with a self-locking hook at each end.

Sizes and ratings

11 chain sizes, 6 mm to 26 mm. Working load limit 1.4 to 26.5 t in a straight vertical lift, at a 4:1 design factor. Used in a choke hitch the rating falls to 80% of the figure in the table. Each size has its own Indus part number below.

Grade 100 against Grade 80

Grade 100 chain carries about 25% more than Grade 80 chain of the same diameter, so a given load can often be lifted on a sling one chain size smaller and lighter. The table gives the standard Grade 100 ratings, worked on the same method as EN 818-4. Chain above 26 mm is made to order and its rating is confirmed on the quotation.

Choosing this make-up

A self-locking hook closes and locks as the load comes on and opens only when the trigger is pressed with the hook unloaded, which suits lifts where the load could otherwise unhook.

Identification and certificate

Each sling carries a permanent tag with its serial number, chain size, grade, reach and working load limit, and ships with the manufacturer's test certificate. The rating on the tag and certificate is the one that governs the sling in service.

Ordering

Slings are made up to length. Quote the Indus part number for the chain size and the reach you need, measured from the bearing point of the top fitting to the bearing point of the hook, or send the load, the number of lifting points and the headroom and we will size the sling for you.
