Crash Tested Security Drop Down Bollards with Programmable Logic Controller (PLC) IP68 Waterproof
Hydraulic automatic bollards integrate oil pump units with robust steel frame construction, utilizing soil pressure as the driving force to achieve smooth rising and lowering operations. These security bollards are typically installed at vehicle entrances and exits, rising to block unauthorized vehicle access and lowering to ground level to permit authorized passage.
