Redesign reduces the hazard potential
Whether we develop new products or redesign existing machines, we always do this considering also the safety aspects that are important to minimise the hazard potentials when handling our products as required by the Machinery Directive.
How important it is to pay special attention to product safety could be seen only last year on a competitor’s solar sewage sludge dryer installation in Bavaria where a tragic accident happened. This was even more reason for us to once again look very thoroughly at our safety systems and further improve them.
When we recently redesigned the HUBER Sludge Turner SOLSTICE®, we completely revised the safety system of the entire sewage sludge drying plant.
The HUBER Sludge Turner SOLSTICE® is the innovative heart of the solar sewage sludge dryer and operates in a greenhouse both as a sludge turning and sludge transporting system for the sludge to be dried. Depending on the different specific conditions on site (throughput, air moisture, inside and outside temperature, ...), the especially developed control unit controls the travel and rotation of the HUBER Sludge Turner SOLSTICE®.
The new feature of the safety concept is that the access to the operating area of the automatically operating machine is consistently monitored electronically. Whenever somebody walks into this area, the machine will be shut down by the emergency circuit. This prevents severe injury. It was further of great importance for us to ensure that the safety devices cannot be bypassed and will not be perceived as uncomfortable or disturbing. Their new design is therefore still very functional and user-friendly.
