I. Core Advantages: Lithium Battery Drive + Traveling Cantilever, Solving Pain Points in Heavy-Duty Operations

1. Traveling Cantilever Structure, Overcoming Limitations on Working Radius and Stability
The telescopic/translational cantilever design (travel range typically 0-500mm, some models support 1000mm ultra-long travel), combined with multi-degree-of-freedom adjustable joints, can precisely cover the bolt distribution area of ​​large equipment, eliminating the need for frequent manual tool repositioning; the cantilever is made of high-strength aluminum alloy, with a load-bearing capacity of 50-100kg. During operation, the cantilever supports and disperses the torque reaction force, avoiding torque deviation caused by manual gripping. Compared with traditional handheld wrenches, the operational stability is improved by 80%, especially suitable for the high-strength tightening requirements of large-diameter bolts (M24-M60). 2. Lithium-ion battery-powered cordless drive, balancing portability and long-lasting power. Equipped with a large-capacity lithium-ion battery pack (6.0Ah-10.0Ah per battery, supporting dual-battery alternation), freeing users from cable constraints and making it suitable for outdoor, high-altitude, and other power-free scenarios; employing a high-power brushless motor (power up to 800W-1200W), with a torque output range covering 300-2000N・m, capable of handling bolt tightening in heavy-duty scenarios such as wind power equipment, heavy machine tools, and bridge steel structures; dual-battery operation supports 4-6 hours of continuous work, and fast charging technology (80% charge in 45 minutes) further enhances operational continuity. 3. Precise Positioning + Intelligent Control, Lowering the Operational Threshold
The cantilever is equipped with a graduated scale and locking mechanism, achieving a positioning accuracy of ±1mm, allowing for quick alignment of bolts and reducing repeated calibration time. The machine body integrates an LCD touchscreen, supporting functions such as torque preset, stroke locking, and work counting. Some high-end models feature Bluetooth connectivity, allowing for storage of work data and remote parameter adjustment via a mobile app. A built-in torque feedback sensor corrects the output torque in real time, with an error controlled within ±2%, meeting industrial-grade high-precision requirements.

V. Usage and Maintenance Tips: Extending Equipment Lifespan
1. Correct Usage Specifications
Before Operation: Calibrate the cantilever positioning accuracy and torque sensor, ensure the outriggers are securely fixed, and avoid suspended operation.
During Operation: Keep the cantilever and bolts coaxial to avoid tilting that could cause torque errors. Overtravel and overtorque operation are strictly prohibited to prevent damage to the transmission structure.
Dual Battery Use: Avoid mixing batteries of different capacities. Turn off the power when changing batteries to prevent short circuits. 2. Routine Maintenance Points
Cantilever Maintenance: Clean the guide rails and lead screw weekly and apply grease (lithium-based grease recommended); check the joint locking mechanism monthly to ensure accurate positioning;
Battery Maintenance: Store in a dry, well-ventilated environment. If not used for an extended period (more than one month), fully charge before storage. Recharge the battery every two months;
Regular Calibration: Perform torque accuracy calibration every six months and check battery capacity and transmission efficiency annually to ensure stable equipment performance.
