Part 1 Ramp H-Beam Frame

Create the main structural steel frame for Part 1 of a two-part mobile forklift loading ramp. Use millimeters and kilograms. Use the following coordinate system: * X-axis: ramp length. * Y-axis: ramp width. * Z-axis: vertical direction. The complete ramp will have two modules and a total length of 9,000 mm. Model only Part 1, with the following external dimensions: * Length: 4,500 mm. * Width: 2,200 mm. * Intended maximum operating load: 12,000 kg. Use structural carbon steel with a density of 7,850 kg/m³. Use fabricated H-sections with: * Overall height: 150 mm. * Flange width: 150 mm. * Nominal web and flange thickness: 1/4 inch, approximately 6.35 mm. * Approximate reference mass: 22 kg/m. * Keep the webs vertical and the flanges horizontal. Create the following members as separate named bodies: 1. Two external longitudinal side beams: * Quantity: 2. * Length: 4,500 mm each. * Run parallel to the X-axis. * Position their centerlines at Y = 75 mm and Y = 2,125 mm. * Name them External_Longitudinal_Left and External_Longitudinal_Right. 2. Three internal longitudinal beams: * Quantity: 3. * Total physical length: 4,320 mm each. * Run parallel to the X-axis. * Position their centerlines at: * Y = 587.5 mm. * Y = 1,100 mm. * Y = 1,612.5 mm. Each internal beam must have: * 4,200 mm clear length between the internal faces of the transverse end beams. * An additional 60 mm inserted into the transverse end-beam region at each end. * Total length: 4,200 + 60 + 60 = 4,320 mm. * Position the internal beams from X = 90 mm to X = 4,410 mm. Name them Internal_Longitudinal_1, Internal_Longitudinal_Center and Internal_Longitudinal_3. 3. Two transverse end beams: * Quantity: 2. * Length: 2,200 mm each. * Run parallel to the Y-axis. * Position their centerlines at: * X = 75 mm. * X = 4,425 mm. * Name them Mobile_Leg_End_Header and Fixed_Leg_End_Header. The five longitudinal beams must be distributed symmetrically across the 2,200 mm width: * Total width occupied by five 150 mm beams: 750 mm. * Four equal clear spaces: 362.5 mm each. * Center-to-center spacing: 512.5 mm. Preserve the exact external dimensions of 4,500 × 2,200 mm. At the four external corners, create simple flush structural joints without leaving duplicate solid volumes. Represent the 60 mm insertion of each internal beam into each header. If the exact coping or notch cannot be generated, preserve the correct member lengths and positions and identify the connection detail as pending. Create only the main H-beam frame in this first generation. Do not add the transverse angle bars, legs, wheels, bracing, plates or weld beads yet. Keep all dimensions parametric and generate the editable 3D frame.
