My entire career has been devoted to inspecting/engineering commercial roller doors. I am a licensed professional engineer (including in the state of Florida). This case sounds like somebody opened this overhead door, and without warning the door rolled back down on the plaintiff. The door has counterbalance springs that are designed to hold the door all the way open when it is opened completely, and it will not necessarily hold the door up if you don’t open it fully. There’s a transition point between where the door will close by itself and where it will pull open and stay open. It has to be heavy on the floor and strong when fully open. In between, you don’t really know where that transition point is. This injury is probably not the result of a manufacturing defect or a design defect, but an adjustment may have needed to be made. Springs weaken over time, so the manufacturer could have properly manufactured the door and the installer may have wound springs properly on the day it was new, but, years later, the springs may have weakened and the transition point changed. The location at which this occurred is responsible for maintaining and inspecting these doors, which it seems like they did not do in this case. I am currently working on two cases that are very similar to this one. Most of my early litigation experience comes from being trained as a defense expert during my time at Windsor and Overhead Door, but since early in my career my litigation experience is more 50/50 plaintiff to defense ratio. This seems to be a case I am extremely well suited for, and I am happy to help.
