B&B ARMR
A Division of B&B Roadway and Security Solutions 0B30-9001 Revision E2
A traffic control gate arm to warn the vehicle operator. This gate arm is
positioned on the attack side of the barrier and does not open to allow traffic
until the barrier is fully lowered (stowed), and the gate lowers to block traffic
before the barrier starts to rise (deploy).
Red/amber traffic lights.
Infrared safety beams to detect pedestrian traffic or as an additional vehicle
sensing device.
2 OPERATION
2.1 Introduction
On the automatic version of the B3X, the bollards are moved to the up (or protective)
position with a single, center mounted hydraulic cylinder. When the bollards are in the
raised position, the cylinder is maintained at the system pressure. The speed of operation
is determined by the amount of pressurized hydraulic fluid able to pass to the bollards in
a given amount of time. This can be controlled by the flow control valves which are
located in the hydraulic pumping unit.
2.2 Control
The automatic B3X Bollard System is controlled by the flow of hydraulic fluid under
pressure from the HPU to the cylinder. All control components are connected to the
HPU.
2.3 Operating Time
The operating time for the bollard system is field adjustable at the HPU by varying the
hydraulic fluid flow from the HPU as required. Normal operation cycles range from 6-10
seconds for both up and down. Emergency fast Operation (EFO) is approximately 1.5-2
seconds. The following table illustrates the estimated required flow rates required to
operate. These values are to use only for pump sizing and initial set-up. Actual times
and pressures will vary in field level tests.
Pressure required to raise the bollard: 250 psi. (Does not include hose loss)
