What Is a Non-Spring Barrier Gate?

A non-spring barrier gate replaces traditional spring balancing mechanisms with motor-driven torque control and transmission systems.

Instead of relying on mechanical springs, the system directly controls boom movement through the motor and controller.

Limitations of Spring-Based Systems

Mechanical Fatigue

• Springs undergo repeated compression and extension
• Over time, this leads to fatigue, deformation, or failure

Maintenance Impact

• Requires periodic tension adjustment
• Spring replacement increases lifecycle maintenance cost

Structure of a Non-Spring Mechanism

Key Components

• DC brushless motor
• Gear transmission (planetary or worm gear)
• Control system (variable frequency or servo control)

Control Logic

• Motor dynamically adjusts torque output
• Eliminates dependence on spring-based balancing

Verified Performance Parameters

Typical project-level configurations include:

• Service life: ≥10 million cycles
• Duty cycle: 100% continuous operation
• Operating temperature: -30°C to +70°C

These parameters support usage in high-frequency and outdoor environments.

Impact on Project Maintenance

• No spring replacement required
• No periodic tension adjustment
• Stability depends on motor and control system, not mechanical elasticity

Typical Applications

• High-traffic parking systems
• Industrial and logistics parks
• Urban vehicle access control
• Long lifecycle infrastructure projects
