VXT - B 8Notes:1. The recommended support arrangement for VX units consists ofparallel I-beams extending the full length of the unit. Supports andanchor bolts are to be designed and furnished by others.VXT2. All supporting beams are to be flush and level at top and must beoriented relative to gage line as shown.3. Recommended design loads for each unit support beam shouldbe 70% of the total unit operating weight applied as a uniform loadto each of the unit beams. The support beam(s) for the optionalintake attenuator(s) needs to carry attenuator only, uniform load of250 kg/m. Beams should be designed in accordance withstandard structural practice. For the maximum allowabledeflection of beams under the unit refer to above table.4. All mounting holes have a diameter of 22 mm at the locationsshown.5. If vibration isolators are used, a rail or channel must be providedbetween the unit (and optional attenuator) and the isolators toprovide continuous unit support. Additionally the support beamsmust be designed to accommodate the overall length andmounting hole location of the isolators that may differ from thoseof the unit. Refer to vibration isolator drawings for these data.Baltimore Aircoil
