Yes, when cobot meets resistance it’s built to get stopped. This is called a safety stop. Utilizing latest innovative robotics technologies Cobot Lift will go into safety stop as easily as when only running with cobot. Sometimes Cobot Lift even add to this sensitivity as we are moving higher loads.
No, Cobot Lift tool combines the strength of a vacuum tube with the intelligence of cobot. We measured forces with joints of cobot when combined with Cobot Lift. Despite carrying several times a designed workload, Cobot Lift is not using a full lifting capacity it has been designed for. Majority of the weight carried out by a vacuum tube lift instead. This topic was one of the key investigation points done by Universal Robots prior to our UR+ certification.
Stationary and Mobile Cobot Lifts are designed to be incorporated into machinery or to be assembled with other machinery in order to constitute machinery covered by directive 2006/42/EC.
As such, it is delivered with the Incorporation Declaration. The main reason of this is that Cobot Lift is characterized as only a platform, which add strengths to collaborative robot. On this platform, you are required to attach an end-effector. Unfortunately, we don’t possess information about what should be lifted, how should it be lifted and what is the complete installed automation solution. Therefore, we can’t conduct risk assessment. However, in order to assist other professionals in performing on-site risk assessments (leading to CE certification), we have developed certain guidelines on how to evaluate possible risks with Cobot Lift installations. This is by no means is complete, but we can help you with performing your job with CE certifying the solution.
