ROAD BLOCK
D&S Technology’s Road Block System is a high-speed anti-terror barrier that stops unauthorized vehicles in just one second. It was developed to protect people and facilities from vehicle-based terror threats.
Unlike conventional systems that take over 4 seconds and require long stopping distances, this system enables instant response. D&S developed its own control PC, drive unit, and software, allowing for real-time operation, precise monitoring, and unmanned automation through system integration.
Tested and Passed U.S. Department of Defense Crash Test

Background of Development
Conventional systems require over 4 seconds to operate, making it virtually impossible to stop a speeding vehicle (over 50 km/h) without securing a stopping distance of more than 50 meters. Developed electronic dual-circuit and control technology for continuous high-speed elevation (Patent No. 1545264).
Core Technology 01
Implemented continuous high-speed operation and precise speed control technology.
Differentiation from Other Technologies
01 Achieves high-speed activation within 1 second—3 to 4 times faster than other systems with the same 4KV output.
02 No recharge or recovery time is needed after activation, allowing for continuous high-speed operation.
03 Hydraulic operation ensures excellent durability and wear resistance, with easy maintenance.
Core Technology 02
Using our self-developed control PC (operation workstation) and software, real-time operation, control, alerts, and monitoring of the system are possible. The system also integrates with various platforms to enable full automation.
Differentiation from Other Technologies
01 Supports standard protocols, enabling integration with other systems and unified network configuration.
02 Enables unmanned operation through a centrally controlled PC system.
03 Real-time monitoring of operational status and faults is possible remotely via graphical interface.
