We've got the HKB03 through HKB50 series in stock right now — lead time is usually 2-3 weeks for most sizes, but confirm for the bigger units like the HKB50 since those move slower.
The alumnum-titanium alloy body makes a real difference when you're working in tight spots, it's basically 30-40% lighter than steel tools in teh same class, and the 360° swivel really helps, though the 2.3 kg spec on the smallest model is about right for one-handed positioning in a pipeline trench.
Torque accuracy is ±3% across the board, which is better than most hydraulic wrenches at this price point — for petroleum or metallurgy work that's tight enough, but if you're doing high-precision lab setups you'd want something with ±1% or so anyway.
What you get when ordering is the power head working head combo for whatever size you pick, plus the 700 bar working pressrue means it'll handle most standerd hydraulic pumps, but the hose routing is sometimes tricky in tight spaces so plan for that.
Weight range runs 2.3 kg on little guy up to 39.5 kg on the HKB50, so for the big one you'll want a lifting assist — the construction guys usually rig a sling, and the 50956 Nm max torque is overkill for most but useful for those big flange bolts in metallurgy plants.
Also, the nut size range is 27-200 mm which covers most common fasteners, but the drive sizes KB50-KB200 mean you can't swap between extremes without extra adapters, so check your actual nut specs before ordering.
The minimum torque varies by model, ranging from 227 Nm on the HKB03 up to 5095 Nm on the HKB50, so you'll want to match the model to your specific bolt size.
Yes, the aluminum-titanium alloy keeps the weight low, from 2.3 kg to 39.5 kg depending on model, while still providing the strength needed for tough jobs like petroleum and metallurgy work.
Standard lead time is around 15-20 working days for most models, and MOQ is typically 1 unit for stock items, though custom orders may require a higher minimum.
Yes, the ±3% accuracy is verified under both ISO and CE certifications, and we can provide the test certificates with your shipment if needed.
Absolutely, the 360° swivel is designed for tight spaces, allowing you to reposition the wrench without removing it from the nut, which is ideal for confined areas in petroleum and construction sites.
