Anti-Collision Devices are used as important parts of material handling systems to avert bumping of two adjacent cranes running on the same track. Operating principle of these devices depend on retro reflective infrared wave based theory. Components like reflector, sensor module and emitter are used to design such products. Offered Anti Collision Devices have IP55 protection rating and their sensor can cover 3 meter of distance. Alarm signal generated by these devises has significant role in controlling the operation of cranes. Consistent operation, low maintenance body, utilization of cutting edge technology and low operating cost are some remarkable features of these anti-collision products.
