Industrial Torque Tools

In field environments such as steel structure bridge construction, wind turbine tower assembly, and heavy machinery installation, the quality of high-strength bolt tightening directly impacts equipment safety and structural longevity. Conventional wrenches struggle to maintain precise torque control, while hydraulic torque wrenches present inherent drawbacks-namely, their bulky size and slow operating speeds. The proper selection of industrial torque tools can, therefore, significantly enhance both operational efficiency and reliability.

Hanpu Machinery has introduced a series of electric torque wrenches specifically engineered for use with high-strength bolts. Taking the TN-12G, TN-25G, and TN-35G models as examples, this trio covers a torque range spanning from 500 N·m to 3,500 N·m and is compatible with bolts ranging from M22 to M36. Utilizing digital control technology, these tools allow for the independent setting of both torque values ​​and rotation angles-or for their synchronized control-delivering high repetitive accuracy. Consequently, they are ideally suited for applications where strict requirements regarding bolt preload are paramount.

For field operations where no power source is available, the DS cordless lithium-ion torque wrench offers an ideal solution. Powered by a 48V lithium-ion battery, it features a torque range of 300 N·m to 8000 N·m and is capable of tightening high-strength bolts up to size M52. On a full charge, it can continuously tighten approximately one hundred bolts-sufficient to handle the workload of an entire shift. The unit is lightweight and designed for single-person operation.

In situations where the workspace is extremely confined-such as inside equipment enclosures or between pipelines-Hanpu's TC-9B and TC-21B right-angle electric torque wrenches provide the solution to these challenging problems. Their 90-degree angled design allows for operation in close proximity to obstructions, while a digital controller ensures that the output torque consistently remains within the specified range. The TC-9B covers a torque range of 400 N·m to 900 N·m, while the TC-21B covers 900 N·m to 2100 N·m; both models are compatible with both metric and imperial bolts.

Hanpu possesses 30 years of experience in manufacturing and R&D, and its products are exported to numerous countries. Whether you require electric, lithium-ion, or manual torque tools, you can visit our website to view detailed specifications or contact our technical team.
