all cts rigibot automation systems now feature the exclusive crest safety arm trigger switch assembly
The concept is simple but the effects far-reaching in terms of machine protection and personal safety.
You've all seen it: damage that occurs when an automation load collides with an obstacle in its path, such as a console countertop or a vertical object placed too close to the machinery. Due to the variables of human error, it's impossible to eliminate this type of occurrence altogether, so the technical strategy is to greatly minimize the damage of impact.
Crest's remarkable safety arm trigger switch is designed to detect force that results from arm contact with an obstacle, and to signal the PLC to stop the Rigibot immediately so that a correction can be made. Force detection is omni-directional, which means that contact with virtually all obstacles will be detected.
The safety arm trigger switch assembly is fully adjustable for a very broad range of load weights. It is now a standard feature on all Crest CTS Rigibot systems, including the CTS-250, -500, -1000 and higher. The assembly may also be ordered for retrofitting to existing Crest cleaning systems with CTS Rigibot automation.
Omni-directional force detection
All new CTS systems are equipped with this exclusive safety arm trigger switch assembly.
ALSO: Retrofit units are now available for quick and easy in-stallation on most existing CTS Rigibot systems.
