We have asked Boris Zils, Product Manager for Crane and Platform Lifter at MOBA, this and several other questions.
Boris, what is a safety and redundant system and what problem does it solve for the customer?
Answer: Modern machines benefit from complex electronic systems, improving functionality and increasing efficiency.Those systems are reliable and comply with high quality requirements.With that said, we have to ask ourselves the following question: ""What about the potential risk if a component fails? What if that causes an accident and put human life at risk?"" Safety systems detect such a failure, keeping the machine in a safe mode and minimizing risk.
What are the obstacles to overcome and what are the minimum requirements to fulfill?
Answer: It is not just the safe structure of the components that has to be considered. A double channel system with cross comparison, called redundancy, is one way to achieve this. It is also very important to define the ""real"" requirements together with the customer and to qualify them. Our sensors are for example able to ""learn"" temperature differentials. Result is that the sensors are able to correct themselves under corresponding temperature conditions. With that method, a 10 times higher accuracy can be reached.
Are there other markets or applications a system like this could be beneficial for?
Answer: Safety systems are mainly requested to avoid accidents and to protect human life. On the other hand, manufacturing processes also need to be repeatable and safe. Possible failures can become very expensive.Therefore, safety systems will increase in complex and critical manufacturing processes.
Boris, in a perfect world, where would you like to see the trend going in 3 to 5 years?
Answer: The world is following the route of evolution! Evolution is not just the survival of the strongest, it is also the success through intelligence. Intelligent systems will not only assist us, they will take more and more important and essential functions over. We need to make sure that those systems are safe!
Thank you Boris, for these insights! I learned a lot and definetly understand safety and redundant systems a bit better.
oktayk: I completely agree with Mr.Horn and Mr.Aparo. And I want to add ""Any job can not be important than human healty"". Our job is safety and we can not be relax after the job is finished on the machine. All finished job is adding more responsibility to us. Because of these reasons we have to think every time redundant.:)11.12.2015 0 points
mitch: Hello Jutta,the technical solutions adopted to meet the essential requirements of safety and health protection, to resort to the most effective technical means available at a reasonable cost, taking into account the total cost of the category of machinery concerned and the necessary risk reduction. ""
So the machine manufacturers are not required to implement technical solutions that are still in the research stage or technical means do not commonly available in the market."" However, ""they must take account of technical progress and adopt the most effective and appropriate technical solutions to the machine in question, when these are available at a reasonable cost.
Firstly the inherent stability of the machine;
- Secondly, where there is a continuing risk of loss of stability, you should install the necessary devices and protective equipment to prevent the machine from tipping or falling over. In this regard, the manufacturer has to consider the foreseeable misuse of the machine which may result in the risk of rolling or tipping over. The necessary protection measures may include, for example, the endowment of electronic controls on outriggers, speed limiters, devices for controlling the position, sensing devices of the overload and the time and inclination sensing devices;
- Third, to the residual risks that can not be completely eliminated by these devices, you must provide appropriate indicators such as, for example, tachometers, inclinometers, anemometers, in addition to information, warnings and instructions necessary to ensure that operators can avoid situations that could lead to a roll or tip the machine during any phase of its existence.09.12.2015 0 points
jutta: What is the perspective of other industry members on that? Where are we heading to in the next couple of years?09.12.2015 0 points
