When tightening bolts at heights, the margin between success and disaster is razor-thin—the DS-8000 offers you an extra layer of security. For wind turbine towers, bridge bearings, and large-scale steel structures, a single improperly tightened bolt can lead to staggering costs for subsequent inspections and remedial work. Even worse is the risk of a safety […]
While using a standard wrench relies on manual feel, a high-torque electric wrench relies on precise data. In scenarios such as factory equipment installation, automotive assembly lines, or mechanical maintenance, one often encounters situations where both the tightening angle and the torque value must be monitored simultaneously; missing either could result in cracking an aluminum […]
Shandong Hanpu Machinery Industrial Co., Ltd. is currently experiencing a peak in shipments, with the factory grounds bustling with activity. The products being exported—electric shear wrenches independently developed by Hanpu—are bound for Germany. All the electric shear wrenches in this batch have passed rigorous testing by a third-party agency commissioned by the German client. The […]
To address torque requirements in the 6,000 N·m class, Hanpu offers two electric wrench models utilizing distinct technical approaches. The DS-6000 centers on a 48V lithium-ion battery, emphasizing portability and intelligent functionality: the complete unit weighs just 8 kg, features a rotational speed of 3 rpm, delivers high-precision accuracy of ±3%, and includes an OLED […]
The torque wrench is an indispensable tightening tool in the bolt fastening process, having evolved through manual, electric, and battery-powered stages. Manual torque wrenches are suitable only for specific scenarios—such as those involving a small number of bolts, low torque requirements, or confined working spaces. However, when faced with large clusters of bolts or various […]

We sincerely invite customers from around the world to visit our booth and experience firsthand the cutting-edge advancements in high-strength bolt fastening technology. […]
Specialized Fastening Tools for Bridge Engineering: An Analysis of the Hanpu Bridge Bolting System. As bridge engineering projects evolve in scale and complexity, traditional bolting methods are increasingly unable to meet the demands of high-standard construction. Consequently, achieving precise and controllable pre-tensioning—while simultaneously ensuring construction efficiency—has become a key area of focus within the industry. […]
DS-8000 Cordless Torque Wrench: Making High-Strength Bolting Operations Effortless In applications such as wind power installation, steel bridge construction, and heavy machinery manufacturing, the tightening of high-strength bolts often entails high physical exertion, significant time consumption, and elevated safety risks. The DS-8000 (8000 Nm) Cordless Torque Wrench was engineered specifically for these demanding conditions—delivering ample […]
In high-altitude operations and field construction sites, dragging long cables often means low efficiency. Hanpu Industrial has launched the DS series of lithium-ion battery torque wrenches, combining high torque with portability, along with high-precision electric torque wrenches (TL/TN series), providing users with a comprehensive solution usable both with and without power. A revolutionary breakthrough in space: […]
In the installation and maintenance of large equipment such as wind turbine towers, heavy machinery, and bridge steel structures, the quality of bolt connections directly determines the safety of the overall structure. However, traditional torque testing equipment is often bulky and difficult to transport, frequently requiring bolt disassembly for testing during on-site operations, which is […]
