They're dragging a 5-ton steel beam across a factory floor, and that narrow gap design is what keeps the chain seated under load—no slip, no sudden drops, just steady tension through the clevis pin.
Each hook gets proof loaded at 2.5 times the working load limit before it leaves, and we batch-test to EN1677-1 with a 4:1 safety factor built in, so you're not guessing where the failure point sits. The quench and temper cycle runs tight on hardness specs, usually within 38-42 HRC across the run, and we hold the COA for every lot if you need to trace it back.
What it does is take the full 15-ton rating on the heavy end, but most buyers go with the 1.12t or 3.2t for overhead chain slings—the narrow gap actually matters more at lower capacities where side-loading is common. We've had customers run these through 10,000 cycles at 1.5x WLL without deformation, but that's fatigue-rated, not guaranteed for infinite life.
Powder coating is standdard in red or yellow, but real test is the batch consistency—we pull random samples form each heat treat load and run a tensile check, and if any unit falls below 4x WLL, the entire batch gets retested or scrapped. ISO9001 and CE certs are on file, and BV inspection is avaliable if your compliance team demands third-party eyes.
Anyway, the 10-ton hook is actually easier to handle than the 15-ton for most rigging—the clevis pin hole is the same diameter, so you're swapping chain sizes without changing hardware. We usually have stock on the 1.12t through 8t, but the 15t runs about 20 working days lead time (confirm before ordering).
You can choose between red and yellow powder-coated finishes. Both offer good corrosion resistance for industrial lifting environments.
It comes with ISO9001, CE, and BV certifications. We can provide the relevant documents upon request to verify compliance.
We typically stick to the standard capacity steps within that range due to the forging and tempering process. If you need a specific non-standard capacity, let us know your requirement and we’ll check feasibility with our production team.
For standard sizes and colors, lead time is usually 2-4 weeks depending on order volume. We can give you a more precise timeline once you confirm the quantity and specifications.
Store them in a dry, indoor area away from moisture and chemicals. The powder coating protects against rust, but keeping them clean and dry will extend their lifespan.
