TS-20 Cordless Railroad Wrench | 400–2000 N·m Battery Torque Wrench for Rail Fasteners

TS-20 Cordless Railroad Wrench

Product Overview

The TS-20 Cordless Railroad Wrench is a battery-powered torque tool designed for tightening and loosening rail fasteners in track maintenance and construction. It replaces pneumatic impact wrenches in environments where compressors are impractical-such as tunnels, remote sections, or urban areas with noise restrictions.

It delivers a calibrated torque range of 400 to 2000 N·m with an accuracy of ±3% of full scale, verified per ISO 6789-1:2017. The tool uses a brushless motor and dual 18V 5Ah lithium-ion batteries, providing enough power for 80–100 M24 rail bolts per charge under standard conditions (20°C, dry rail).

Manufactured in Zhengzhou, China, the TS-20 is built with an IP54-rated housing for dust and splash resistance, and operates reliably in temperatures from -10°C to +50°C-conditions commonly encountered in European and Southeast Asian rail networks.

Key Features

TS-20 cordless railroad wrench LED display

1. Precise Torque Control
Set exact torque values (e.g., 1200 N·m) via LED interface-no guesswork.

2. Auto-Reverse After Tightening
Automatically rotates back 5° to release socket-reduces jamming on rusty bolts.

3. 360° Rotating Handle
Lockable at any angle for use in tight spaces like switch mechanisms.

4. Dual Modes: Torque-only or Torque+Angle (for critical joints per EN 15044).
5. Low-Power Protection: Shuts down at 20% battery to maintain torque accuracy.
6. Settings Memory: Retains last torque value after power-off.
7. Field Kit Included: 2 batteries, rapid charger, carry case, and 2 sockets (M24/M27).

Field Applications

The TS-20 cordless railroad wrench is used by maintenance teams in the following scenarios:

Underground tunnels – no exhaust, no external power required.
High-speed rail maintenance windows – rapid bolt replacement during short outages.
Mountainous or remote track sections – lightweight and portable.
Switch and crossing zones – precise torque on irregular bolt patterns.
Steel railway bridges – using Torque+Angle mode for structural joints.
Locomotive workshops – servicing bogie and coupler bolts.
Emergency track repairs – deployable within minutes.
Mobile maintenance vans – fits in standard tool cabinets.
Export projects – in use since 2022 in Russia, Spain, Indonesia, Malaysia, and Singapore.

Advantages Over Pneumatic & Corded Tools

Pneumatic wrenches require air compressors, hoses, and dry air supply-adding weight, noise, and setup time. Performance drops in cold weather due to moisture freezing in lines.

Corded electric wrenches need 220V power, limiting use in tunnels, bridges, or remote tracks without generators.

The TS-20 cordless railroad wrench offers:

Zero setup – ready to use in under 10 seconds
Quiet operation – below 75 dB(A), suitable for urban areas
Consistent torque – unaffected by air pressure or voltage fluctuations
Lower total cost of ownership – no fuel, no compressor maintenance
