The goal of an elevated equipment platform is to support equipment, storage, or human traffic. This discussion focuses on the gravity or vertical loads and how to determine the proper load rating or specified loads for your platform. Gravity loads are separated between dead load and live load. Dead load includes the self- weight of the structure and components that are securely attached to the permanent structure. Live load is a variable load such as human traffic and product weight.
Like every other industry, there is much jargon in the Material Handling and Logistics industry. Knowing the proper terms when discussing an upcoming project with potential suppliers and project managers is vital to making sure each project is a success. There is nothing worse than using the wrong terminology and then spending more time explaining a project than actually executing it.
Seismic forces are used as a representation for the displacement and movement that a structure would undergo during a seismic event. The seismic forces are directly related to the height, seismic weight and number of levels of the structure. Seismic weight is determined from the dead load of the structure consisting of framing members, decking, railing and equipment securely attached to the structure.
Concrete deck is viewed by consumers as having the most flexibility to adjust equipment locations, handle large point loads, and support heavy material handling equipment such as pallet jacks and light forklifts. This may be true, however, there are drawbacks to selecting a concrete deck over a roof deck, bar grating, or floor plate system.
