Chain Slings & Assemblies

Buying chain slings for an Ontario fleet

A chain sling is the most repairable, most inspectable lifting sling you can put in a fleet, and the one most likely to be pulled from service over paperwork rather than wear. Every assembly TELEMAC supplies ships proof-tested, fitted with a permanent identification tag and accompanied by the certificate that ties that tag back to the batch of chain and fittings it was built from. That documentation is what a Ministry of Labour inspector, a rental branch manager or your own competent person asks for first.

We supply chain slings in Grade 100 alloy steel as standard. Grade 100 carries roughly 25% more working load limit than Grade 80 at the same nominal chain size, which usually means a lighter sling for the same lift, a real consideration when a rigger handles the same 4-leg assembly forty times a shift.

Configurations we stock and build

• Single-leg (1-leg) slings, the workhorse for straight vertical picks and for choking loads where a basket hitch is impractical.
• Two-leg (2-leg) slings, the standard for loads with two established pick points; rated at a 60° included angle unless otherwise specified.
• Four-leg (4-leg) slings, for pallets, skids, frames, moulds and precast forms with four lift points. Supplied with a sub-master link assembly and chain hangers so the unused legs can be secured rather than left swinging.

Browse 5/16", 3/8", 1/2" and 5/8" chain in single, double, triple and four-leg assemblies. Reach selections vary by chain size and leg count; the selection table lists each combination separately. Standard and heavy duty builds have distinct SKUs. Other configurations can be requested through Custom Solutions.

What our assemblies come with

Our slings are built with self-locking hooks, not spring-latch hooks. A spring latch retains a hook; a self-locking hook will not open under load even if the latch is compromised. For rental fleets and multi-crew sites where the person rigging the load is not the person who inspected the sling, that difference is worth the small cost delta.

Each assembly carries a durable tag stamped with the manufacturer, grade, working load limit, serial number, batch number and date of manufacture. The serial ties to the proof-test record and to the certificate supplied with the shipment, so the chain of documentation stays intact through the sling's service life.

Working load limits and sling angle

The rated capacity printed on the tag assumes the sling is used within the angle it was rated for. As the included angle between legs decreases, tension in each leg rises sharply, a two-leg sling at a 30° included angle carries almost four times the leg tension of the same sling used vertically. Multi-leg capacities shown on our product pages are stated at a 60° included angle unless noted. If your crews routinely rig at tighter angles, tell us on the quote and we will size the assembly accordingly.

Documentation and Ontario requirements

Ontario's Construction Projects regulation, O. Reg. 213/91, requires that lifting devices and slings be rated, marked and inspected, and that a record be available. TELEMAC supplies every lifting product stamped, tagged, proof-tested and documented to support those obligations, and manufactures to the applicable ASME B30.9 and CSA standards. We can supply to the requirements of other provinces on request. Full detail is on the Compliance page.

Chain spare parts

Rebuilding or extending an assembly in-house, rather than buying a new one, is normal, so long as the repaired sling is re-rated and re-tagged to its lowest-rated component. We stock the parts that come up most often:

• Master links, sized to match your chain so the link is not the component that sets the assembly rating
• Clevis hooks, grab, sling and self-locking configurations
• Swivel hooks, 15 and 20 ton, for loads that need to rotate under load
• Swivel road plate lifting rings, for plate and cover handling
• Chain spreader bars, 36", 48", 60" and 72" spans, with custom lengths built to spec
• Lifting clutches ("duck bills"), for precast pick points
