Nippon Kiki Kogyo co. Hydraulic Vehicle Intrusion Prevention Barrier Block Gate

Manufacturer: Kuramoto Instrument Manufacturing Co., Ltd
Model: Hydraulic Vehicle Intrusion Prevention Barrier Block Gate
Features
- The system is designed as a hydraulically operated barrier that prevents unauthorized vehicle entry from external areas, thereby ensuring secure access control.
- In emergency situations, the steel impact plate rises rapidly to block approaching vehicles, while the rising operation is completed in approximately two seconds to provide immediate protection.
- The structure delivers high strength and durability, and its superior impact resistance has been validated through crash tests conducted with real vehicles.
- When in the stored position, the barrier remains level with the road surface, thus allowing smooth and uninterrupted passage for heavy vehicles.
- Although the basic structure is shared, two configurations are available depending on installation conditions, including a shallow type with reduced pit depth and a flush type that eliminates internal cylinder steps and obstructions.
- Both configurations adopt a standardized design, which enables installation to be completed within a short time through simple foundation work.
- Custom designs are also available to meet specific installation environments and application requirements, thereby ensuring flexibility in various usage conditions.
