I am a Mechanical/Automotive Engineer, though I have recently been given some structural work. I will try to keep this as short as possible. My company purchased a new CMM machine which came with an I-beam mounted trolley for loading. The max load on the trolley is 2000 lbs. The I-beam is to be mounted underneath an existing 3" thick concrete floor. The floor joists are 3 ft. apart and are I believe 4" wide I-beam. The I-beam will be simply supported at one end by an outside concrete wall, and than welded to each floor joist. The other end of the beam will overhang the last joist by approximately 3 feet to gain the necessary travel of the crane. The question is, what type of deflection am I allowed at the overhanging end of the beam? There are no standards for this application that I know of. Also, what type of deflection would be allowed on the flange of the I-beam due to the mounting of the crane? Any help will be greatly appreciated.
Thanks in Advance

Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each personâ€™s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now

Itâ€™s easy to fall in love with your own CAD design on the computer screen, but itâ€™s how everything fits together off the screen that really matters. Beyond the design, products need to solve real-life problems or provide huge benefits that genuinely merit separating money from wallets. Download Now
