Frequently Asked Questions (FAQ)
Yes, when a Cobot meet resistance it is built to stop. This is called a safety stop. The Cobot Lift utilizes the collaborative robot technology will go into safety stop as easily as when only running with a Cobot. Sometimes the Cobot Lift even add to this sensitivity as we are moving higher loads.
Like with other Cobot installations it depends on the task that is carried out e.g. if a cobot (or Cobot Lift) is working above 2 meters of height, a fence would be required to ensure the workers’ safety in case a load would be dropped. We therefore always recommend a risk assessment of the full installation is done.
No. The Cobot Lift tool combine the strength of a vacuum tube with the intelligence of a Cobot. We measured the forces within the joints of the Cobot when combined with the Cobot Lift. Despite carrying several times the designed workload the Cobot is not using the full lifting capacity it was designed for. The majority of the weight is carried by the vacuum tube lift instead. This topic was one of the key investigation points done by Universal Robot prior to our UR+ certification.
No, The general Cobot Lift or the Mobile Cobot Lift is intended to be incorporated into machinery or to be assembled with other machinery to constitute machinery covered by Directive 2006/42/EC. As such it is delivered with a Declaration of Incorporation. The main reason for this is that the Cobot Lift is only a platform that add strength to the Cobot. On this platform you need to attach an end-effector. We do not have information about what is to be lifted, how and the complete installed automation solution and therefore we cannot assess the risks. To assist other professionals in doing a risk assessment on site (leading to a CE certification) we have developed suggestive guidelines on how to assess risk with Cobot Iift installations. This is by no means complete, but can help with performing the work with CE certifying the solution.
