Magnetek’s collision avoidance systems can help prevent accidents before they happen, protecting people, the facility, and the cranes. Our collision avoidance systems prevent crane-to-crane and crane-to-end stop collisions which increases operator safety and reduces system maintenance.
Magnetek offers three collision avoidance systems which can be applied to all types of overhead cranes or monorails with adjustable frequency drives, soft starters, or contactor controls. Multiple configurations are available so customers can choose the exact functionality, size, and style to fit their application needs. All Magnetek’s collision avoidance systems are rated IP65 or better. The collision avoidance systems are “fail-safe”, which means that if the sensor would lose power, motion of the crane would be stopped and restricted.


Types of Sensor Technology

Magnetek’s ReFlx 45 product uses a modulated visible LED light signal, while the ReFlx 120 product uses an infrared light signal. These light signals are transmitted at a reflective target. The receiver senses the reflected signal from the target. The information is processed and the appropriate relay opens, providing for slow down or stoppage of the motion. The type of protection needed for the application will determine the number of systems required. Depending on the device selected, ReFlx has a detection range between 3 and 120 feet.

Magnetek’s LaserGuard2 collision avoidance product is the most technologically advanced system available, using self-monitoring optical lasers to check a crane’s position. Its multi-distance detection feature is flexible enough to manage crane-to-crane and wall-to-crane operations. The configurable set-point range of this laser based system (from 8 inches to 150 feet) allows the ability to monitor distances between cranes, trolleys, and monorail carriers, and prevent collision between this equipment. Laser based systems offer the most precise positioning and are particularly useful in an automated environment.

Collision Avoidance Systems Impact on Safety

Collision avoidance systems are increasingly being added to material handling systems as the demand for products that increase workplace safety grows. They intervene when necessary to prevent accidents, making the workplace safer and reducing maintenance costs. These systems not only provide peace-of-mind, but are a reliable means of preventing human error.
