XCMG XE2000 Excavator High-Strength Support 318307500 – A Guardian of Structural Safety in Mining Industries

Core Product Value

The XCMG original XE2000 high-strength support (part number: 318307500) is integrally forged from 42CrMoA special alloy steel. Through finite element topology optimization design, it achieves an ultimate load-bearing capacity of 55 tons, specifically designed for extreme working conditions such as mining and rock breaking. It has passed ISO 12135 fracture toughness certification, and its fatigue life exceeds 12,000 hours, a 90% improvement over ordinary supports, making it a core structural support component ensuring stable equipment operation.

Five Major Technological Breakthroughs

🛠️ Military-Grade Forging Process

• Uses 42CrMoA ultra-high strength alloy steel (tensile strength ≥1250MPa)

• Integral die forging using a 10,000-ton hydraulic press (no welding stress concentration)

• Deep ion nitriding treatment (surface hardness HRC60-65)

⚡ Structural Reinforcement Design

• Three-dimensional mesh reinforcing rib structure (stiffness increased by 45%)

• 22mm thickening design for key components

• Stress diffusion channel

🔍 Intelligent Monitoring System

• Pre-set strain gauge interface (supports real-time stress monitoring)

• Laser positioning reference hole (installation accuracy ±0.1mm)

• Laser calibration of wear limit

🛡️ Extreme Environment Verification

• -45℃ low-temperature impact energy ≥90J
• Salt spray corrosion resistance for 2500 hours
• Passed a magnitude 7 earthquake simulation test

🔧 Easy Maintenance Design

• Modular quick-release structure (50% reduction in replacement time)

• Hydraulic-assisted installation interface

• Dedicated calibration tool included
