How to Achieve Two-Point Synchronized Lifting Without Eccentric Load? An Engineering Solution Based on a Servo Winch
I. Background
In high-altitude firefighting equipment systems, engineers often assume:
Two winch points acting simultaneously will achieve synchronized lifting.
However, in practice, common issues include:
One side moves first, the other lags behind
Uneven structural stress distribution
Winch tilting or jamming
Core Issue: The problem is not whether it can "move," but whether it can achieve stable synchronization; otherwise, there are serious safety hazards.
II. The Problem
Traditional methods customers have tried:
Using a single winch
Using two ordinary winches driven independently
Manual synchronization adjustment
Common Issues:
❌ Synchronization error uncontrollable
❌ Obvious start-stop (shock/vibration)
❌ Long-term operational instability
This often leads to rework or complete system redesign.
III. The Solution
To address the above issues, we have adopted the following solution in multiple high-altitude firefighting projects:
Dual-Drum Servo Winch Synchronous Control System
Core System Design:
Servo motor drive system
Encoder real-time feedback
Dual-drum winch structure
Control system (supports PLC expansion)
Principles of Stable System Synchronization:
1️⃣ Dual-drum winch structure: Ensures synchronized winding/unwinding of two wire ropes, avoiding eccentric loads.
2️⃣ Servo closed-loop control: Provides speed/position/torque closed-loop control.
3️⃣ Encoder feedback: Enables real-time position monitoring for precise stopping.
4️⃣ Synchronization algorithm control logic: Ensures coordinated and consistent operation of both execution points.
IV. Applications
Widely applied in:
Two-point synchronized lifting systems
Automated equipment traction systems
Rope-driven firefighting robots
Industrial door synchronization control
