DZE4 Barrier Gate for Industrial Park Underground Parking Entrance

Project Overview

This project is the vehicle access control renovation for the underground parking entrance of a modern industrial park. The clear width of the passage is 4.5 meters. The DZE4 barrier gate is adopted, equipped with a 4.5m double fence arm and non-spring machine core.
The entrance is a vehicle passage supporting civil air defense works. The traffic mainly consists of passenger cars with medium daily traffic volume. The project requires long-term operational stability and anti-fatigue performance of equipment. The device is deployed in an open-air environment and needs to withstand temperature differences between day and night as well as dust.

Barrier Gate Specifications

• Model: DZE4 Barrier Gate
• Arm: 4.5m two fence arm
• Machine core: non-spring design, no traditional balance spring
• Maximum applicable passage width: 4.5m
• Operating temperature range: -35℃ ~ +70℃
• Protection class: IP54
• Opening / closing time: 6 seconds

Implementation Notes

1. Civil foundation: Concrete foundation is constructed on site to fix the gate cabinet horizontally and reduce vibration during operation.
2. Arm installation: The 4.5m double fence arm is assembled in sections with fasteners tightened. Horizontal and vertical limits of the arm are preset before delivery.
3. Wiring & commissioning: Linked with vehicle recognition system. Open and close limits are calibrated. The non-spring movement relies on motor torque for balance. Spring tension adjustment is not required, eliminating the risk of spring aging.
4. Safety features: Built-in loop detector interface. When vehicles stay under the arm, anti-crush protection will be triggered.

Operation Benefits

Conventional spring-balanced barrier gates suffer from spring fatigue and elasticity attenuation after repeated lifting, requiring regular calibration and replacement. The DZE4 non-spring machine core removes the vulnerable spring component, reduces mechanical wear points and maintenance workload.
The 4.5m two fence arm provides high visibility, warning pedestrians and non-motor vehicles of arm movement. It fits entrance scenarios with mixed pedestrian and vehicle flow in industrial parks. The equipment operates continuously at this parking entrance to meet daily vehicle access control requirements.
