Automatic Lane Barrier / ALB

Transpeed A3D Double Boom Ultrafast Automatic Lane Barrier
< 0.3sec Closing | Opening Speed

Speed and Stability are your Ultimate Choice

Super High Speed ALB has solved the problem of vehicle tailgating which resulted in collection failure or mistakes. It greatly reduces
human intervention and unnecessary congestion at the ETC lane.

The most important feature of digital control system (STEP) is its precise control over start/stop position with STEP, it is able to
achieve stopping precision of within <0.2 degree. The design also eliminates the usage of mechanical braking mechanism and
cushioning device in decelerating the barrier. The speed of the barrier can be adjusted independently. The A Series barrier has indeed
achieved a major technical evolutional breakthrough in the automatic lane barrier/ALB industry.

All A3 Series ALB are fitted with a vehicle Loop Detector. The reaction speed can reach up to 50ms. Normal Loop Detector’s reaction
speed is around 120ms. The loop detector is able to detect a vehicle entering the loop detection area while the barrier is moving down
and it will stop immediately thus avoiding the barrier boom damaging the vehicle.

High Speed Opening, Increasing Toll Lane Effectiveness
With Transpeed A3’s unprecedented high speed opening and closing of just 0.3 seconds, the traffic throughout of toll lanes are improved drastically, allowing each lane to accommodate a larger amount of traffic. In the long run, especially for main
toll stations that govern the entrance into and exit out of city, the system will increase the overall efficiency of the toll
collection operation. In addition, toll lanes equipped with A3 automatic lane barrier are set ready for upgrade to ETC’s “FreeFlow” operation.

Eliminate Interference, Avoid Incorrect Toll Charging
Interference occurs when a tailing vehicle with an OBU is charged for an access make by the vehicle in front that
doesn’t possess a valid OBU. This is a prevalent issue at most ETC system and a super high speed automatic lane barrier like A3 offers a good solution to the issue. Due to the super speed demonstrated by A3 in boom opening, the gap/distance
between the boom and the vehicle detection loop is significantly reduced. This in turn will reduce the size of the vehicle
detection loop and disallow 2 vehicles from entering the loop at the same time, thus eliminate interference and incorrect
toll charging. The improvement is achieved without installing any additional loop nor optical curtains that are usually
costly and require much maintenance.

Collision Safe Technology, Exceeding Safety Regulations
The A Series Automatic Lane Barrier uses a patented “DQI” speed retarding technology. In the unlikely event when the ALB may come into contact with the vehicle in the final moment (within 25ms), the motor operating power will reduce to only 15%
of its normal operating speed and will stop immediately. Coupled with the use of a soft and flexible fibre boom, damage
to vehicle is minimised, if not totally eliminated.

Anti-Smash Car Safety Technology
High speed vehicle detector (HVD) can be connected to this automatic lane barrier. In the event that a vehicle is detected when the barrier is closing, the ALB will react instantly and its arm will be lifted swiftly.

High Durability
STEP digital control system does not use any mechanical braking and is a gearless construct. This eliminates issues
and problems which are typically found in conventional systems, such as high maintenance, high failure rate and fast
depleting gear. The STEP system is suitable for prolong operation in a highly demanding work environment. With the
various functional gains in its design, the STEP architecture has truly achieved its original goal of creating barrier that is
both maintenance free and of low failure rate.

No Brake Sensors
By using a numerical system to directly and accurately control the motor stroke, the traditional method of braking the
arm while stopping is revolutionalised. A brake sensor unit is no longer required in this ALB.

Flexible Speed Setting
By adopting the STEP digital control system, speed of the A-Series automatic lane barriers can be adjusted. The opening and closing speed of the barrier arm can be set differently. During opening, the ALB can be set to open at the fastest time, while during closing, the speed can be set to close at moderate speed to increase safety.

Soft Fiber Arm Soft Arm KB6
This arm is made up of high strength and light weighted carbon fibre. Its outer layer is made of highly elastic fibre. This
make the barrier arm light in weight, crash resistance, and does not damage the vehicle nor hurt any personnel during
its operation.
