Electric torque wrench

Electric Torque Wrench

The numerically controlled rechargeable torque wrench is a self-developed and produced torque-setting tool for assembling and disassembling bolts. It achieves precise torque output through the dual control of the single-chip microcomputer motor software and the torque sensor, so as to realize the torque-setting assembly of bolts. This tool is widely used in the assembly and disassembly of bolts in heavy industries such as petroleum, natural gas, petrochemicals, metallurgy, mining, aerospace, military industry, railways, power, and construction machinery.

Special Features

Working pressure 700 bar max
Constantly repeated accuracy ± 3% across the full stroke
With an LCD display, there is no need for a torque comparison table, and the torque accuracy is ±3%.
It features a dual-speed design and is equipped with a two-speed manually switchable planetary gearbox.
When the decrease in battery power affects the accuracy of torque output, the control system will automatically turn off the battery.
The power handle and transmission mechanism can rotate 360 degrees, and it is equipped with a mechanical locking system to protect the operator.
It is suitable for occasions where there is no power source and large torque precise disassembly and assembly are required, improving the assembly quality and efficiency.
It comes with 2 lithium batteries and a fast charger as standard, and the charging time is within 60 minutes.
Customers can optionally choose a 5.0Ah lithium battery according to the actual situation for more lasting power.

Specs

Specifications of Electric Torque Wrench

Electric torque wrenches come in diverse specifications. Torque ranges vary widely: 50 - 300N·m for small - scale tasks like electronics repair, 100 - 1000N·m for general automotive and equipment work, and 500 - 5000N·m+ for large - scale industrial jobs. Square drive sizes include 1/4", 3/8", 1/2" and 3/4", with small ones for delicate parts and large for big nuts. Driving modes are AC (powerful, for fixed sites) and DC (battery - powered, for mobility). Accuracy levels are typically ±3% (±1% for high - end), and weights range from 1 - 5 kg, catering to different usage scenarios.

Features of Electric Torque Wrench

Dual speed design with gearbox

The device features an eye catching dual speed design. It is carefully equipped with a manually switchable two speed planetary gearbox. This enables users to smoothly switch between different speeds with ease and adapt to various operational requirements effortlessly.

Auto power off for low battery

When the decrease in battery power affects the accuracy of torque output, the control system will be activated immediately. It will automatically and rapidly cut off the battery supply. This protection mechanism can prevent poor performance and potential damage caused by low power torque issues.

360degree rotation handle for safety

The power handle and the transmission mechanism have excellent 360 degree rotation capabilities. In addition, it is equipped with a well developed mechanical locking system. This system plays a crucial role in ensuring the safety of operators and guaranteeing a safe working environment.

Ideal for high - torque work without power

It is highly suitable for use in scenarios where there is no power source but high precision and high torque disassembly and assembly are required. By being able to handle such tasks effectively, it significantly improves the overall assembly quality and efficiency.

Standard lithium batteries and fast charger

As a standard configuration, it comes with two high quality lithium batteries and a fast charger. The charging time can be conveniently controlled within 60 minutes, achieving a quick turnaround. This ensures continuous operation without long term interruptions due to power problems.

Optional 5.0Ah lithium battery for long lasting power

Customers can flexibly choose a 5.0Ah lithium battery according to the actual situation. This choice can ensure a more long lasting power supply, especially for long duration or high power demand tasks, providing more convenience and reliability.
