If you’re torquing 2-inch studs on a mine headframe at -15°C, the last thing you need is a tool that binds up or can’t reach the nut—this hollow low-profile head slips into a 50mm gap and spins full 360°×180° without repositioning the pump.
It hits 70MPa max working pressrue with a torque span form 237Nm all way up to 85000Nm, and that ±3% accuracy holds even when you push the ratchet past 800 cycles or so. The aluminun-titanium alloy body keeps the 6 to 35kg weight manageable, but what it does is handle the high-strength design so the casing doesn’t crack under repetitive shock loads in sub-zero weather.
Actually, we see these mostly on pipeline flange makeup and heavy mining equipment—it’s better than a standard square-drive wrench for those tight, blind spots. A limitation: the manual hydraulic operation means you’re controlling the flow with a hand pump, so for really high-speed production bolting, you’d want a pneumatic backup (usually 2-4 weeks lead time on that option).
Also, one power head swaps across multiple working heads, so you’re not buying a whole new unit for different bolt sizes. For ordering, we hold common models in the 5000-12000Nm range ready to ship, but confirm the working head dimensions—some of the larger 85000Nm heads need a bit more clearance than the spec sheet might suggest.
Our standard MOQ is 5 units per model, but we can be flexible on smaller orders for first-time buyers — just reach out and we'll see what we can do.
For standard models, lead time is usually 15–20 working days. Custom orders may take a bit longer, depending on the specs.
Yes, we include ISO and CE certificates with every order. If you need additional documentation like a test report, just let us know.
No, the WHCW is designed for -20°C to 60°C. Operating outside that range could affect performance or damage the unit.
The WHCW power head is built to our standard interface, so it's interchangeable with our working heads. Compatibility with other brands isn't guaranteed — better to check with us first.
