Crane Anti-Collision Systems

Electronic Technologies Employed by Magnetek for Collision Avoidance Systems 
If the application requires collision avoidance between cranes, monorail carriers, and other obstructions, Electromotive Systems has the solution. Below are some of the technologies Electromotive Systems applies to collision avoidance for the overhead material handling marketplace.

ReFlx 120 and ReFlx 120 “Plus” 
Intended for use with overhead crane bridges and trolleys to prevent collisions or limit their approach to adjacent bridges and trolleys. The systems are designed to be immune to most electrical noise including that which can be created by variable frequency crane controls and other parasitic interference affecting the reliability of RF-based systems. The range of this system is from 10 to 120 ft. It uses a two- channel infrared sensor, which allows for a separate slowdown and stop command when used with Electromotive Systems IMPULSE crane controls.

Laser Based Distance Detection 
Laser based distance detection and collision avoidance are primarily used in an automated environment where the distances between monorail carriers or cranes can be relatively great. The range of a laser based system (from 0 to over 1000 ft.) allows the ability to monitor distances between cranes, trolleys and monorail carriers, and when interfaced with a PLC, can be used to prevent collision between this equipment. Laser based systems also offer the advantage of precise positioning accuracy which is critical in an automated environment.
