CORAL
Fully retractable bollard for access control
Automatic oil-hydraulic system, 230 Vac
 
DESIGN AND MANUFACTURING
Recommended to control access to residential areas and also for commercial and industrial applications.
OIL-HYDRAULIC
Hydraulic lock for parking in the high position (standard) and emergency manoeuvre for lowering with release key supplied.
Solenoid valve (optional) for automatic descent in the event of a power failure.
Tested for intensive use at low and high temperatures.
EASY ACCESS TO THE OIL-HYDRAULIC COMPONENTS
The handy housing position of the motor pump and oil-hydraulic actuator inside the bollard allows for easy maintenance and reduces service and installation times. In this way the components are also more protected, rust and other factors of deterioration are prevented.
SIMPLE AND QUICK TO INSTALL
Reduced weight of the pit so that no particular excavation or brick works are needed. Cataphoresis treated and polyester powder coated scratch-proof steel cylinder, head with rubber edge. Hall effect limit switch sensors, LED lights (optional).
VERSATILE
A vast range of command and safety accessories allow for reliable and precise control of the installations. The electronic control unit can be set so that it can manage several bollards at a time.
