We needed something that could actually handle a full structrual lift without corners on safety, so I went with the SFST-500—it's 500 tons at 25MPa working pressure, which is overkill for some jobs but better than having a failure mid-lift. The cylinder diameter is 145mm and stroke is 75mm, body height sits at 591mm, and extended height hits 666mm, so it fits under most bridge bearings we deal with. It's heavy-duty steel all around.
Basically, the team running bridge bearing replacements and structural realignments will use this with the synchronous control system, which keeps everything level when you're lifting a multi-ton span. It's not meant for quick roadside repairs or light jacking—that's what the smaller units are for, and trying to use this for that would be a waste of capasity and setup time. You'll want the electric or diesel pump option depending on site access; we usually go with electric for indoor or confined spaces.
75mm stroke might sound short, but for bearing swaps and shim adjustments, it's actually enough—most buyers don't realize you're not lifting the whole bridge, just taking the load off a single point. The pressure relief valve and overload protection are built in, which is non-negotiable for us given the liability on these projects. I've seen cheaper jacks without those features fail under load, and that's not something you want to explain to a client.
We've got RoHS, ISO, and CE certs on this, so compliance with international standard is covered—no extra paperwork headaches for our QA team. Lead time is usually 4-6 weeks, but I'd confirm stock before ordering because demand spikes during summer construction season. Also, the oil pump is sold seperately, which caught me off guard the first time, so factor that into your budget.
One detail that came up in testing: synchronous control requires all jacks in the system to be matched, so if you're adding this to an existing set, verify the flow rates are compatible—otherwise you'll get uneven lift and have to stop mid-operation. Teh 25MPa working pressure is tighter than most general-purpose jacks, but that's what gives it the stability for precision work. Anyway, the order's placed for two units with electric pumps.
We typically require a minimum order of 2 units for the SFST-500, but we can discuss single-unit orders for urgent projects. Just let us know your volume, and we'll see what we can do.
Standard lead time is around 25-30 working days after order confirmation. If you need it faster, we can prioritize production for an additional fee—usually cutting it to 15-18 days.
Yes, we include the original RoHS, ISO, and CE certificates with every shipment. If you need them in advance for bidding or compliance checks, just ask, and we'll email you copies.
We can adjust the stroke length up to 100mm on this model, but the cylinder diameter is fixed at 145mm for structural integrity. Customizations usually add 10-15 working days to production.
Store it in a dry, indoor area with temperatures between -10°C and 50°C, and keep the cylinder fully retracted. We recommend covering it to avoid dust buildup on the seals and the pressure relief valve.
