Springs have traditionally played an important mechanical role in barrier gate mechanisms. By balancing the weight of the boom, a spring allows the barrier gate to perform its basic opening and closing movements.
As barrier gates move toward higher-speed and high-frequency operation, however, the drive mechanism is also evolving.
The WEJOIN G30 uses a non-spring mechanism and directly controls boom movement through a dual-drive system, representing one approach to non-spring barrier gate technology.
In a conventional barrier gate, the spring is mainly used to balance the boom.
This structure has been widely used for many years, but a spring is a mechanical elastic component. During long-term operation, factors such as fatigue, tension changes, and adjustment requirements need to be considered.
Therefore, as barrier gates operate at higher frequencies, reducing maintenance associated with spring mechanisms becomes one potential direction for mechanical design.
G30 replaces the traditional spring-balancing mechanism with WEJOIN's independently developed 3D dual-drive non-spring mechanism.
Two drive motors control vertical and horizontal movements respectively, while different transmission mechanisms create the three-dimensional motion trajectory.
The key concept is:
Instead of relying on a spring to balance the boom, the drive system directly controls boom movement.
Therefore, non-spring design is not simply a change to one component. It represents a different approach to barrier gate mechanism design.
G30 uses a permanent-magnet synchronous DC motor with variable-frequency control. According to the official specifications, its operating speed is 0.3 seconds.
When a barrier gate operates at high speed, the drive system needs to control the movement process more precisely.
A non-spring structure reduces the mechanical dependence on a conventional spring-balancing mechanism, allowing the drive system to directly control boom movement.
Therefore, from an engineering perspective, the non-spring mechanism and high-speed 3D motion are not two completely separate selling points. They are components of the same mechanical design approach.
In B2B technical communication, the term “maintenance-free” should be used carefully.
A non-spring design can reduce maintenance related to spring replacement and tension adjustment, but a barrier gate remains a complete electromechanical system.
Motors, gears, bearings, controllers, and external safety devices still require inspection and maintenance according to actual operating conditions.
A more technically accurate market expression is:
Non-spring design reduces maintenance requirements associated with traditional spring mechanisms.
This wording is more appropriate for engineering projects and international B2B customers.
G30 is not an isolated product.
WEJOIN currently has a dedicated non-spring barrier gate category featuring multiple non-spring models.
From a product development perspective, non-spring technology has expanded from a single high-speed product into a broader range covering different boom lengths, operating speeds, and application requirements.
This indicates that non-spring mechanisms are becoming an important direction for mechanical innovation in automatic barrier gates.
