What are the Different Robot Hours?
One of the reasons industrial robots are considered a good investment is because of their long lifespans. Industrial robots that are well maintained can operate for hundreds of thousands of hours. This is why robot hours are commonly referred to as opposed to the age of an industrial robot, similar to how mileage is used for cars. Robot hours are a good measurement of the robot’s condition as they can be indicative of wear and tear, shelf-life, maintenance needs, and the robot’s reliability. Robot hours can fall under a few different categories. The following is a breakdown of the different robot hours and their meanings.
Operation HoursOperation hours are the robot hours that are most commonly referenced. Operation hours are the total hours a robot has operated in its entire lifespan. They are typically referenced when buying or selling used robots as they can be used as an indicator of the condition and lifespan of a robot. For instance, on a listing for a used FANUC Arcmate 120ic/10L, the operation hours may be listed as 20,000.
Many also believe operation hours are indicative of the wear and tear on a robot, but that is not always the case. Operation hours can also include the total time a six axis robot has been powered on and not necessarily running. Industrial robots can operate for over 100,000 hours when well-maintained, so just because a robot may have high hours it is not necessarily an indication of excessive wear and tear. It is also important to note the hour meter is typically located on the controller of the robot. When looking to purchase a used robot, a buyer should ask if the controller or robot have ever been exchanged because the operation hours listed on the controller may not be accurate for that robot.
