TS-20 Cordless Lithium Battery Socket Wrench – High-Torque Railway Bolt Tightening Tool

The TS-20 Cordless Lithium Battery Socket Wrench is a professional-grade railway maintenance tool engineered for high-efficiency, high-torque operations in remote or power-limited environments. Weighing just 7.2 kg, this lithium battery powered socket wrench delivers precise torque control while offering unmatched portability for track crews.

Equipped with an 18V 5Ah lithium-ion battery, the TS-20 can tighten or loosen up to 400 rail bolts on a single charge and recharges fully in under 40 minutes. It's the ideal cordless socket wrench for railway maintenance, especially suited for fastening track bolts, switch components, and structural connections where external power isn't available.

The TS-20 serves as a versatile railway bolt tightening tool across diverse scenarios:

1. Securing track fasteners and fishplate bolts on mainlines and sidings.
2. Installing or removing bolts in complex switch and turnout zones.
3. Emergency or routine bolt replacement during track maintenance to reduce line downtime.
4. Fastening foundation bolts for transmission towers and substation structures near rail corridors.
5. Field operations in remote areas without access to grid power-perfect for a lithium battery powered socket wrench.
6. Tightening high-strength structural bolts in steel bridges or rail-mounted facilities.
7. Ensuring safety-critical torque accuracy for rail infrastructure connections.
8. Bolting metro and high-speed train components such as bogies, couplers, and chassis.
9. Securing wheel hubs and engine mounts during rolling stock maintenance.
10. Supporting mobile repair teams and engineering machinery service stations with reliable track maintenance tools.

1. Precision torque sensor with ±1% full-scale accuracy (±3% FS in real-world use), ensuring reliable performance for critical railway maintenance tasks.
2. LED display with intuitive buttons to preset torque values; tool auto-stops at target torque-ideal for consistent railway bolt tightening.
3. Automatic micro-reverse function prevents reaction arm jamming, enhancing safety during high-torque operations.
4. Power-off memory retains settings after battery removal or restart.
5. Supports torque-only or torque+angle control modes-no need for torque conversion charts.
6. Powered by an 18V 5Ah lithium-ion battery with charge indicator; capable of processing up to 400 bolts per charge-making it a true cordless socket wrench for railway maintenance.
7. Smart low-battery shutdown protects torque accuracy and extends battery life.
8. 360° rotatable handle and drive head with mechanical lock for ergonomic and safe operation in confined spaces.
9. Fast charging in under 40 minutes; standard kit includes 2 batteries and 1 rapid charger for continuous field use.
10. Engineered for high-torque, precision tightening or loosening in demanding rail environments-among the most efficient track maintenance tools available.
