What is an Anti Collision Device?
Basic construction of an Anti Collision Device is very simple , it Consists of a sensor & a relay.
Safety First
It is exactly like an emergency braking system where the Sensor is continuously aware of its surrounding environment to detect the presence or absence of any foreign equipment . When an ACD Is mounted on a machine , first it is calibrated according to the user requirement.
Reaction to External Objects
The reaction time of the sensor of your anti collision device is an important factor depending upon its application.If your machine is moving at 20 meters / second and the reaction time of your sensor is 0.5 Seconds, the machine will move almost 10 meters ahead before it is stopped by the ACD. The ACD should be tested in its final working environment after mounting and calibration .
Need for Anti Collision Device
An Anti Collision Device is categorized as a safety device which prevents an accident due to the collision of two machines.Without such a device, manually or automatically operated machines can travel outside their working area and damage nearby machines, equipment or structures and can cause dangerous situations .

More about Infrared Light
This infrared light can also be used to communicate data between devices. All kinds of remote controls in home appliances such as Air Conditioners & Televisions use the IR spectrum. But to prevent natural sources of infrared light such as the sun,from interfering with the safety devices, the infrared radiation from the emitter is modulated at a certain frequency .This Modulated data is then received by the Infrared receiver and demodulated to extract the data. Infrared receiving devices are made up of photodiodes which are semiconductor based integrated circuits which react to infrared light by inducing a small current. Infrared transmitting devices are made up of semiconductor material such as GaAlAs & GaAs. The transmitters emit the IR light in front of them within a certain angle exactly like your Car HeadLIghts.

Anti-Collision Devices for EOT Cranes: Safeguarding Precision and Safety
In the bustling world of material handling, Electric Overhead Traveling (EOT) cranes play a vital role. These steel giants gracefully lift and transport heavy loads, ensuring the smooth flow of goods in factories, warehouses, and construction sites. But what keeps them from colliding with each other or other structures? Enter the unsung heroes—the anti-collision devices (ACDs).
Understanding Anti-Collision Devices
An ACD is like a vigilant traffic cop for cranes. It prevents collisions between multiple cranes sharing the same runway or between a crane and nearby structures. Picture this: two cranes moving toward each other, their paths intersecting. Without an ACD, disaster looms. But with this ingenious safety device, the cranes slow down, pause, or even stop, ensuring they never collide.
How Do Anti-Collision Systems Work?
The basic concept is elegantly simple: an ACD consists of a sensor and a relay. Let’s break it down:
Sensor:
The sensor continuously scans its surroundings, like a watchful sentry. It detects the presence or absence of other equipment, whether it’s another crane, a wall, or any obstruction. Think of it as an emergency braking system for cranes.
Calibration:
When an ACD is mounted on a crane, it’s calibrated based on user requirements. The reaction time of the sensor matters—a critical factor. Imagine a crane hurtling along at 20 meters per second. If the sensor takes half a second to react, the crane will travel about 10 meters before the ACD kicks in. Calibration ensures precision.
Infrared Waves:
ACDs use retro-reflective infrared waves. The emitter sends out infrared light, and the reflector bounces it back to the sensor. When two cranes are at an ideal distance, the reflected waves don’t reach the sensor, allowing normal operation. But if they get too close, the sensor alarms and takes action.
Features of Anti-Collision Systems
Safety First:
ACDs prevent accidents due to crane collisions. Without them, cranes could wander outside their designated areas, damaging nearby equipment or structures. These devices not only safeguard material handling equipment but also protect operators.
Infrared Technology:
Infrared-based sensors operate in the invisible spectrum. They’re like silent watchers, analyzing crane movements without disturbing the human eye. These sensors work reliably even in high temperatures, making them ideal for logistics applications.
Distance Set Points:
ACDs allow precise control over the detection distance. By mounting an emitter on one crane and a reflector on the other, both cranes can stop simultaneously. It’s like synchronized dancing in mid-air.
Microprocessor-Based Modules:
Advanced ACDs use microprocessors. They’re smarter, more efficient, and capable of handling complex scenarios. Some modules even have dual relay outputs for added flexibility.
Anti-collision devices are the unsung heroes of crane safety. They ensure that cranes move harmoniously, avoiding collisions and potential disasters. So, the next time you see an EOT crane gliding overhead, remember the invisible shield—the ACD—that keeps our industrial world in balance.
