Battery-Powered Impact Wrench (High Torque 3-Speed Model)

Applicable Scenarios

Specifically designed for large-scale steel structure projects (e.g., steel structure splicing of river-crossing bridges), core component fixing of high towers (e.g., flange bolts of communication towers), ultra-high pressure assembly of engineering steel pipe frames, and automotive industrial maintenance (e.g., disassembly/assembly of heavy truck drive axle bolts). It focuses on precise and efficient handling of large-sized nuts.

Core Features

Industrial-grade brushless motor: power attenuation rate ≤5% (after 4 hours of continuous operation), suitable for high-intensity continuous construction.

Dual adjustment of 3-speed rotational speed (1800/2300/2800RPM) + 3-speed torque (1200/1500/1700NM): compatible with full-spec M12-M24 nuts.

Intelligent disassembly button with overload protection: automatically powers off when the torque exceeds the workpiece's bearing limit, avoiding bolt breakage or workpiece deformation.

1.9KG body made of high-strength ABS material: anti-drop and impact-resistant, and can operate stably in harsh outdoor environments (e.g., rainy days, dusty environments).

Technical Parameters

Rotational Speed	1800/2300/2800RPM (3-speed adjustable; low-speed high torque for loosening tight bolts, high-speed for quick installation of regular bolts)
Voltage	21V (industrial-grade stable voltage, ensuring power output under extreme working conditions)
Lithium Battery Capacity	6000mAh (supports 10 hours of intermittent operations; 24-hour non-stop construction can be achieved with a dual-battery set)
Torque Range	1200NM-1700NM (industrial-grade torque; it only takes 10 seconds to loosen M24 tight bolts)
Loosening Nut Range	M12-M24 (compatible with self-locking nuts, no additional unlocking tools required)
Bare Machine Weight	1.9KG (balancing power and operational flexibility, safer for two-person cooperative high-altitude operations)
