Advanced MicroProcessor based safety device
The ultrasonic Anti Collision Device system works on the principle of Ultrasound waves.
The Sound emitter and sound detector are tuned at the same Sound frequency of 40Khz. When the
transmitter sends a burst of ultrasonic sound, it is reflected back by the walls of the crane
and the receiver detects it and activates an alarm signal and stops or reduces the speed of the
The time taken after the burst is send and received and with speed of sound Distance is calculated.There is a Display which shows Distance in meters. If the obstacle is in range then by rotating the Knob, Relay range can be adjusted and another relay can be adjusted by directly pressing the switch.
Thus if two cranes are out of range they will operate in normal speed. The sensing Distance is adjustable from 0.01m to 5 meters. The Device is designed for crane applications and is suitable to work for 24x7 hrs. This product does not require Laser Pointing Device.
Easily Set the Detection Distance.
To Prevent Crane to Crane Collision 2 Sets of ultrasonic ACDs are required.1st ultrasonic
ACD to be mounted on 1st Crane
2nd ultrasonic ACD to be Mounted on 2nd Crane
Such a system will allow both the cranes to stop at the same time.
Next, position both the overhead cranes within 5 meters at the precise distance you want the power to be cut. Once, ACDs are properly mounted, rotate the distance knobs in the clockwise direction until the relay indicating light switches on. This means the distance is set . To Prevent Crane to Wall Collision 2 Sets of ACDs are Required.
Such as system will prevent collision of crane with the surrounding structure in the cross travel or long travel direction. 1st ACD to be mounted on the left side of the Crane and 2nd ACD to be Mounted on right side Crane.
