Customizable Heavy Duty Strand Jack for Industrial and Construction Applications

Stock is decent on the 45-ton unit, but the 300-ton version usually needs a 6-8 week lead time depending on strand count — confirm before ordering, and the packaging for larger loads is standard heavy-duty crating, not climate-controlled or anything since it's steel.

Working pressure sits at 31.5 MPa with a 500mm cylinder stroke, and you're looking at 3 to 20 strands of 18mm diameter depending on your load, with lifting speed ranging form 2 to 5 meters per hour which is actually fine for controlled positioning of bridge segments or industrial components.

It's basically not suited for quick repetitive lifts where you'd want a traditional winch, but for those one-off heavy lifts where you need to hold a compnent for hours or days the self-locking anchor is solid, and the computer synchronized control means you can manage multiple jacks from a single panel (usually we see 4-unit setups for the bigger bridge jobs).

CE and ISO certified, and the high-grade steel construction holds up well; the 18mm strands we typically stock have low-relaxation spec that's better than some generics we've tested but honestly if you're doing 300-ton lifts you'd want to verify the strand batch numbers directly with us since that's a tight tolerance.

Also, what it does is provide virtually unlimited lifting height if you have secure load-bearing points at each stage — teh modular strand approach means you're not limited by a fixed jack height, but the cylinder stroke itself is just 500mm per cycle so factor that into your timeline.

An anchor type detail most buyers don't think to ask: the self-locking mechanism holds at any position, so you can safely stop mid-lift for alignment checks without hydraulic creep, which is pretty much whole point of the design anyway.
