So you're tightening bolts on a large flange or wind turbine tower and can't get a standard impact wrench in there—we see that a lot, and the 1:76 ratio on this MDNF-200P turns your arm into a 20,000 Nm machine, with the input just needing a 3/4" drive ratchet.
Accuracy within ±5% is pretty standard for manual multipliers this size, and actually for strucutral steel or heavy equipement bolting that's usually tight enough—most buyers go with the 10mg tolerance range or so, but we always include the COA with each unit.
It weighs 38kg and the output end takes a 2-1/2" square drive, which handles nut sizes from S105 up to S145 (roughly M72 to M100 bolts) so you'll need a couple of guys or a hoist to position it, but once it's on the nut, the planetaries do the real work.
One thing we've found in the field is that teh chrome finish holds up better than bare alloy steel against corrosion in humid shipyards, though it'll still scratch under heavy use—it's not a tool for frequent drop-and-drag scenarios on concrete.
Also, lead time is usually 30 days or so form order, but we've got a batch finishing up right now (check stock), and box dimensoins are 170×264×(163.75-276.25)mm so it fits standard freight pallets.
Anyway, your RFQ mentioned 12 units for a refinery project—our company can do MOQ 5 and ship within 2 weeks if you confirm the nut size range matches your bolt specs.
It handles bolts from M72 up to M100, with a nut size range of S105 to S145.
Yes, we can supply a calibration certificate upon request to confirm the ±5% accuracy.
Our MOQ is typically 1 unit for stock items, but we can discuss bulk orders if you need more.
It ships in a heavy-duty plywood case to protect the 38kg unit. The package includes the multiplier, a reaction bar, and a manual.
We can customize the input or output size, but the standard is 3/4" input and 2-1/2" output. Lead time for custom orders is about 2-3 weeks.
