Technical Manual
Key Points:
The steeper the incline, the greater the resistance, reducing the winch’s effective pulling power.
Figures are based on rolling loads, such as vehicles or trailers on wheels.
When using a hydraulic winch, it’s essential to understand how slope inclines affect the winch’s effective pulling capacity.
Always ensure your winch is rated above the expected load for the slope you are operating on.

Important Tips
These figures apply to rolling loads (not dead weight or dragging).
Ensure proper use of snatch blocks or pulley systems for higher loads.
Regularly inspect your winch and recovery gear for safety.

Advantages of Series Wound Motors
High Starting Torque: Ideal for electric vehicles, locomotives, and heavy-duty machinery where strong initial torque is needed.
Robustness: Handles overloads and fluctuating loads well; reliable in harsh environments.
Simple Control: Easier to operate and maintain compared to permanent magnet motors.
Variable Speed Operation: Supports a wide speed range with appropriate control systems.
Cost-Effectiveness: Often more economical in large high-torque applications.
High Power Density: Compact and powerful — suitable for automotive and aerospace sectors.
Note: The optimal choice between series wound and permanent magnet motors depends on your specific application, cost requirements, efficiency goals, and environment.
