TiSO high security automatic (hydraulic) bollards are designed to prevent unauthorised vehicles access to secure areas and to provide the highest level of antiterrorism protection. Generally, this type of equipment is installed at high risk sites where maximum protection to the public and assets are required. Typically, where there could be a high risk of heavy vehicle attack such as public places (stadiums, fairgrounds), government institutions, or military infrastructures etc. These bollards are installed in either single or multiple units with an external hydraulic station and PLC, connected via the hydraulic hoses. A separate push button control unit is supplied for manual control which is usually installed within the security office. Additionally, this equipment can be easily integrated and interconnected with ACS and other vehicle access control equipment (arm barriers etc.).
