Factory Direct Supply Hydraulic Bridge Jacking Equipment with 31.5MPa Working Pressure

They’re primarily moving bridge segments or heavy steel structures, that 31.5MPa working pressrue handles it without breaking a sweat, and the PLC system keeps every jack locked within ±0.5mm of each other the whole lift — we’ve actually used the 150-ton model on three different overpass retrofits. 2. Positioning accuracy that tight means you don’t stress the concrete or waste time shimming afterward, so even though we usually go with teh top end of that 45-300 ton range, the basic 500mm stroke covers most standerd pier adjustments and segmental launches we run into. 3. But the big catch is the weight (some units push 2,460kg), so crane logistics get real fast and our crew basically needs two days on site for a full setup instead of one with lighter kit. 4. You’ll mostly see railway bridge contractors and viaduct crew using these, though we’ve had one client try them on heavy lifting for a dam project — wouldn’t recommend it unless you pad the budget for custom anchoring (fixed prestressed anchors mean limited slack). 5. Lead time usually runs 4-6 weeks ex-works, though HM46 anti-wear fluid and IP65 cabinets mean you don’t have to baby them in rain or freezing conditions down to -20°C, so we don’t chase seasonal shutdowns for pre-orders. 6. MOQ’s typically one pump station with two jacks, but you’ll want a minimum four units and spare strands (18mm, 3-20 per group) for even load distribution on big spans — that’s what our purchasing haggled down form initial quote.
