Hi For those running EMI Labs was wondering what procedures you use to move Test Racks in and out of EMI Chambers, We use custom made ramps, which we put over the door threshold, aligning the front wheels on the ramp, then pushing the unit up and over into the chamber.
Items which seem important: 1. Wheel Size and base dimension 2. Swivel wheels not aligned with ramp ( Most Test racks have swivel wheels fitted at the front) 3. Communication between team members to move the rack 4. Custom Alloy ramp made from 1/4" checker plate causing a lip where it touch's the floor 5. Equipment with handles in rack placed near the top, (operator may try to use to move test rack) 6. Poor center of gravity (equipment position for ergonomics) Some of our 19" test racks are quite heavy, lightning generators at 400lbs and other test racks such as amplifiers up to 650lbs These are commercial units and I believe met safety requirements when purchased. My questions are: What procedures/solutions do you have to move equipment and avoid a tipping situation? >From a standard point of view Is there any direction on Wheel Size, Wheel base, height weight and Ramp Inclination and run off which I could use to support possible improvements?
