Actually handles bars up to 40mm diameter without breaking a sweat, the 2.6kW motor keeps torque steady at 400Nm even under sustained load—pretty much the sweet spot for most commercial rebar connections on site. We typically see these used for column splice joints and beam connections where you need consistent clamp force without teh guesswork of manual tools.
The automatic torque shutoff is what sets it apart from impact wrenches, it stops the drive exactly at the preset value so you're not crushing threads or overstressing the coupler. One thing we've noticed is operators tend to set it at 350Nm for standard grade 60 rebar (usually 2-4 weeks of daily use before they find their preferred setting), but the 400Nm ceiling handles heavy-duty specs when you need it.
Weighs 15kg and measures 30×40×50 cm, so it's not a one-hand tool but the titanized carbon steel body holds up well to job site drops. The CE and ISO9001 certs are there, though we've had some clients ask about IP rating—we don't have one on file, but it's been used in light rain without issues. Also runs on standerd 220V/50Hz, just make sure your site power is stable.
Most buyers go with this over hydraulic units because of that it's faster to cycle between connections, no waiting for pressure buildup between bars. It's not ideal for overhead work though—the weight gets tiring after an hour or so, we usually recommend a boom suspension rig for that. Better than pneumatic torque wrenches for consistent output across temperture swings, the electric motor doesn't lose torque when compressor line is shared.
What it does is it tightens to a hard stop at the coupler face, no need to check with a torque wrench afterward if you trust the calibration. We do a quick bench test before shipping with a torque transducer (HPLC-grade accuracy is overkill for this, but the ±3% tolerance is tighter than most construction specs require). Anyway, stock levels vary—we usually have units ready but confirm lead time for large orders above 10 pieces.
Our standard MOQ is 10 units for the ERTW-400, but we can negotiate smaller quantities for first-time orders or sample testing.
Lead time is typically 15-20 working days for stock orders. Custom voltage or branding could add 5-7 days.
Yes, we provide both ISO9001 and CE certificates with each shipment. You'll get a copy in the package or digitally before dispatch.
No, it's designed specifically for up to 40mm rebar diameter. Exceeding that could damage the tool or result in poor connections.
It comes in a reinforced cardboard box with foam inserts to secure the 15kg unit. We also offer custom crating for bulk orders at no extra charge.
