This is the fifth blog is a series on what makes a good glass factory trolley.
The most common structures for factory trolleys are A-frames and L-frames. The main benefit of an A-frame is that glass is shared across two storage area providing easier and quicker access to items. The main benefit of an L-frame is that it's narrower and easier to move around a factory.
Rather than focus on the pros and cons, in my opinion, the more important aspect of the trolley is the angle of the lean. Ideally product will be placed on trolleys at around 7 degrees allowing safe storage and movement of the product. Most transport systems prefer around 5 degrees lean at this creates a more space efficient trolley for transportation. The crossover is when 5 degree transport trolleys are used in a factory. Unless there is a form of retention (such as poles or safety arms) 5 degrees is too steep and can lead to glass falling of the trolley with rework and health and safety implications.
As more companies move to transport trolleys for glass transportation this is becoming more of an issue.
