What is the Shacman X6000 Chassis Step Bracket_lh？

  • Shacman X6000 Chassis Step Bracket_lh: Robust Left-Hand Support for Secure Cab Access​
  • Engineered to provide stable mounting and load distribution for commercial vehicle steps, the Shacman X6000 Chassis Step Bracket_lh integrates a modular system of high-strength brackets and precision fasteners—Front/Rear/Upper/Lower brackets-LH, Hexagon flange bolts, and Hexagon bolts/nuts—to deliver superior structural rigidity, vibration resistance, and long-term durability. Designed for the X6000 series, this left-hand (LH) bracket assembly ensures reliable support for cab steps in logistics, construction, and off-road operations.​
  • Core Structural Components: Reinforced Bracket Framework​
  • The Chassis bracket assy-LH forms the backbone of the step support system, comprising four key components for balanced load-bearing:​
  • Front bracket-LH (8mm-thick high-strength low-alloy steel, yield strength ≥ 550 MPa) anchors the forward end of the step, with a contoured design that aligns with the vehicle’s frame rail to distribute 40% of dynamic loads (max 300 kg) to the chassis.​
  • Rear bracket-LH (6mm-thick quenched-tempered steel, tensile strength ≥ 650 MPa) reinforces the rear mounting point, featuring a gusseted profile that increases bending resistance by 35%, critical for absorbing impacts from heavy foot traffic or tool storage.​
  • Upper bracket-LH and Lower bracket-LH (5mm-thick hot-rolled steel) create a vertical support column, with pre-machined slots (tolerance: ±0.2mm) for precise alignment with step platforms and fender structures.​
  • Mounting System: High-Strength Fastening for Vibration Resistance​
  • A precision fastening network ensures secure integration with the vehicle chassis:​
  • Hexagon flange bolts (grade 12.9, M14 x 60mm) secure the Front/Rear brackets-LH to the frame, torqued to 180–200 N·m with serrated washers to resist 25G vibrations (ISO 16750-3 compliant), maintaining 98% clamping force after 100,000 cycle fatigue testing.​
  • Hexagon bolts (grade 10.9, M12 x 50mm) and Nuts (self-locking, DIN 980V) connect the Upper/Lower brackets-LH, creating a rigid vertical axis that withstands 1,500 N of lateral force—ideal for off-road articulation.​
  • Material Excellence & Environmental Resilience​
  • Components are optimized for harsh commercial environments:​
  • Corrosion Protection: All steel brackets undergo a 50μm zinc-nickel plating (ASTM B117, 1,200 hours salt-spray resistance), while bolt surfaces feature a lubricious coating to prevent galling during installation.​
  • Temperature Tolerance: Functions reliably from -40°C to +120°C, with steel components retaining 90% of yield strength in arctic cold and resisting thermal expansion (coefficient ≤ 11×10⁻⁶/°C) in desert heat.​
  • Wear Resistance: Bracket mounting surfaces are shot-peened to enhance fatigue life, surviving 2 million cycles of simulated step loading (SAE J2347 compliant).​
  • Compliance & Performance Benefits​
  • Key features enhance safety and maintenance efficiency:​
  • Regulatory Adherence: Meets ISO 6481 for powertrain mounting systems and EN 131-1:2021 for industrial step supports, ensuring global certification and operator safety.​
  • Load Distribution: The bracket system reduces step platform deflection by 50% compared to single-point mounts, extending the lifespan of adjacent components like step mats and fenders.​
  • Maintenance Ease: Modular design allows replacement of Front/Rear brackets-LH in 45 minutes using standard tools, with color-coded fasteners (red for high-torque bolts, black for nuts) to simplify inventory management.​
  • Testing & Reliability​
  • Rigorous validation ensures industry-leading performance:​
  • Static Load Test: Supports 1.5x rated load (450 kg) for 24 hours with ≤1mm deformation, exceeding SAE J1492 commercial vehicle step bracket standards.​
  • Vibration Fatigue Test: After 1,000 hours of 10–2,000 Hz vibration, all fasteners remain torqued within ±5% of specification, with no bracket cracks detected via non-destructive testing (NDT).​
  • Salt-Spray Test: Maintains 95% surface integrity after 1,500 hours of salt exposure, confirming long-term resilience in coastal or winter climates.​
  • Conclusion: Heavy-Duty Left-Hand Support for Enduring Access Solutions.​
