Dual-speed Design, Balanced Efficiency & Precision：

Unique high/low two-speed adjustable system:

• High-speed mode: Rapidly spin up bolts for fast pre-tightening, cut repetitive idle operation time;

• Low-speed mode: Slow constant-torque locking, eliminate over-torque risk, guarantee consistent bolt fastening quality.

  Compared with single-speed torque wrenches, overall construction efficiency increases by over 40%, perfectly matching mass batch assembly and large-scale engineering construction.

 Two Structural Forms to Adapt All Working Conditions：

• VM-D-G2 Straight Pistol Grip: Ergonomic anti-slip handle, high power-to-weight ratio lightweight body, comfortable for long-time horizontal/vertical flat assembly work, easy to transport and operate.

• VM-DA-G2 Elbow Bend Model: 90° bent output head with auxiliary lifting handle, specially designed for narrow cavity, inner box girder, track fastener and other inaccessible dead-angle positions that straight wrenches cannot reach.

  Multiple drive heads optional: 0.75” / 1” / 1.5” / 2” square drive, compatible with all standard industrial heavy-duty sockets.

CNC Digital Precise Torque Control System：

• Color digital control panel, 1Nm incremental fine torque adjustment, real-time display torque value, gear and working status.

• 10 groups programmable preset torque values, gear adjustment mode for quick switching of multi-spec bolts on site.

• Built-in bolt torque reference table, match standard torque according to bolt strength grade and diameter; gain calibration function for rapid parameter correction.

• User hierarchical authority management (administrator / operator), prevent unauthorized parameter modification and misoperation.

• Support third-party intelligent torque calibration, software gain & hardware compensation to extend tool service life.

Anti-fluctuation Stable Torque Output, Suitable for Harsh Construction Sites：

Independent voltage stabilizing unit with input rectification feedback control function, effectively suppress grid voltage surge and fluctuation on construction sites. Torque output will not drift even under unstable temporary power supply. High-rigidity heat-treated planetary gearbox, continuous heavy-load durable, whole machine noise controlled at 80dB. Support 110V/220V dual power supply customization, adapt to domestic and overseas construction power standards.

Optional Industrial IoT Data Traceability Function：

• Real-time tightening result judgment: automatically identify success / failure / incomplete fastening to avoid unqualified products outflow.

• Optional Bluetooth/WIFI torque gateway module, realize IoT interconnection with upper computer and MES production management system.

• Customizable bolt tightening data upload format, support mass data storage, convenient for factory quality inspection, production archiving and full-life traceability.
