I was working with a customer who was needing to handle rolls of plastic & upend them 90 degrees. The individual rolls were about 20” in diameter weighing about 2,000 lbs when stacked and were facing in the horizontal orientation. The customer wanted to load multiple skids at a time. We were able to modify our crate positioner upender to do just that. We made the platform wider to fit all 3 pallets and also put a v shaped retaining plate on it to help retain the load while upending. This solution would help increase productivity considerably as they were only able to do one at a time with an over head crane. The upender is hydraulically operated electrically powered and can also be powered by air.
