Bollard

Hydraulic rising bollards are designed especially for high security vehicle entrances and for locations that has to be closed for motorized traffic on specific times (like private roads, controlled parking areas, industrial areas, shopping lanes, marketplaces etc). Whenever a vehicle collision occurs; bollards will destroy the front suspension system, steering linkage and other parts of the drive system so the vehicle will move only a few more meters and will be inactivated. They can be installed as a single unit as well as in groups. Bollards are driven hydraulically and the hydraulic drive unit is placed in an installation cabinet close to the bollards. In case of power failure bollards can be lowered manually. Typical raiselower time is 3 seconds. Standard unit has raised height of 60 cm but for special requirements up to 90 cm lifted height can be manufactured. With the help of plcmicroprocessor controlled electronics, raiselower function can be achieved by every kind of card readers, biometric readers like fingerprint or hand shape, radio control, onoff switch or keyswitch etc. Besides, safety accessories like loop dedectors, photocells, flashing lights or redgreen lights can be integrated to the control electronics very easily.
