70-Ton Industrial Friction Winch | SEW Motor, PLC Control & High-Precision Traction
Precision Friction Winch Engineered for Heavy-Duty Reciprocating Motion in Energy, Aerospace, Military and Industrial Applications
This European-style industrial friction winch is a custom-engineered 70-ton-class traction system designed specifically for energy storage power stations in Turkey. With exceptional stability, precise control and robust structural integrity, it is built for reciprocating motion, long travel distance pulling, high-frequency industrial operations and synchronized multi-equipment systems.
It is ideally suited for rail-car traction inside energy storage stations, heavy equipment relocation, precision manufacturing lines, special research facilities and high-demand environments requiring accurate positioning, long service life and intelligent control.

1. Key Technical Advantages
✔ SEW Geared Motor: High Power, High Stability

Powered by a SEW high-efficiency geared motor, the winch delivers:
- Strong and consistent torque output
- Energy-efficient operation
- Smooth acceleration and deceleration
- High durability under continuous heavy loads
This ensures reliable traction performance for rail cars and other heavy-duty systems.
✔ Integrated Load Cell for Real-Time Tension Monitoring

A built-in force sensor provides continuous monitoring of rope tension, enabling:
- Overload protection
- Predictive maintenance
- Real-time operational diagnostics
- Safer handling under complex working conditions
Operators gain full visibility of system status at all times.
✔ PLC Touch-Screen Control System

The system includes a PLC-based intelligent control panel with:
- Manual / Automatic dual-mode switching
- Parameter adjustment
- Fault alarms and data visualization
- Improved operational safety and repeatability
This makes the winch suitable for engineering environments requiring precise speeds, repeat positioning and automated workflows.
✔ Absolute Encoder for Position, Speed and Travel Tracking

The absolute encoder provides:
- Real-time counting of drum revolutions
- Accurate calculation of car speed, travel distance and movement trajectory
- High precision even in long-distance or repeated cycles
Perfect for testing platforms, R&D labs, and industrial facilities requiring data-driven motion control.
✔ Optimized Steel Wire Rope Guiding Structure

The horizontally arranged guide wheels:
- Reduce rope running height
- Minimize mechanical wear
- Prevent rope deviation during long strokes
- Enhance safety and extend rope lifespan
Especially effective for traction systems operating in tight spaces or complex industrial layouts.
✔ Ground-Mounted Electrical Cabinet
The separate electrical cabinet ensures:
- Improved heat dissipation
- Easy maintenance
- Enhanced system stability
- Safer long-term operation

Suitable for harsh industrial environments where reliability is critical.
