telescopic hydraulic boom 3d model

Create a realistic 4-stage telescopic rectangular hydraulic boom for industrial applications. The boom must extend from 30 ft retracted to 70 ft fully extended. Use nested rectangular steel sections with matte black powder-coated surfaces, reinforced edges, weld seams, and realistic machining details. Stage 1 is the fixed base with hydraulic power inlet ports and mounting flanges. Stages 2–4 telescope outward progressively with tight mechanical tolerances and visible overlap between sections. Include internal hydraulic routing using red pressure lines, black return lines, and blue auxiliary lines running through all stages. Add quick-connect hydraulic couplers at the tip section for powering tools or attachments. Show realistic hose retainers, sliding wear pads, gussets, bolts, guide rails, and support collars. The model should appear mechanically functional, industrial-grade, and suitable for heavy-duty automation or lifting systems.
