The system works on the principle of retro -reflective infrared
waves. It consists of an emitter and sensor module and a special
reflector. The emitter emits the infrared waves in the direction
of the reflector. The reflector reflects these infrared waves
back to the sensor. The sensor senses the presence of these
reflected infrared waves and activates an alarm signal and
stops / reduces the speed of the crane . Thus if the two cranes
are away from each other then the reflected waves will not
reach the sensor and the cranes operate normally. The distance
between the reflector and the sensor to detect the presence
of infrared waves can be adjusted with the help of the potentiometer
provided on the system. The maximum distances between the
two cranes to generate the alarm signal can be maximum 10
meters. The anti collision system is specially designed for
the Crane application and is suitable for the continuous duty.
Each system consists of an Emitter/sensor module and a Reflector.
The emitter/ sensor module is installed on one crane and the
corresponding reflector is installed on the opposite crane.
Hence to avoid the collision between two adjacent cranes two
sets of each emitter/sensor module and reflectors are required.
