Mechanical structure innovation of the open clamshell grab
Four-link closure mechanism
Jaw plate synchronous opening and closing accuracy± 1.5mm (using laser cutting process)
High-strength alloy jaw plate (thickness 25-35mm, tensile strength ≥850MPa)
Optimized design of pulley block (wire rope life extended to 15,000 hours)
Modular assembly
Bucket split design (single module weight ≤ 8 tons, easy to sea)
Quick connect pin (module change time< 2 hours)
Lightweight carbon fiber parts (35% weight reduction in non-load-bearing structures)
Abrasion resistance strengthening technology
Hardfacing process
The jaw cutting edge is welded with tungsten carbide (hardness HRC65, wear resistance increased by 3 times)
The bucket body is lined with high-chromium alloy (thickness 8mm, impact resistance ≥ 80J/cm²)
Replaceable wear components
Standardized slider design (40% reduction in cost per block)
Bolted side panels (no welding required for replacement, 70% reduction in man-hours)
Optimization of the closing force of Enjue open clamshell grab
Twin hydraulic cylinder drives
Closing force up to 50 tonnes (for 30 m³ hopper)
Pressure compensation valve (keep the closing force constant, increase the packing rate by 25%)
Penetrating enhanced design
Wedge-shaped jaw structure (40% reduction in plunge resistance)
Vibration Auxiliary Device (Frequency Adjustable, Adaptable to Different Materials)
Applications of the Enjue open clamshell grab
Extreme material handling
High abrasion ores
Manganese ore special grab (jaw overlay thickness increased to 12mm)
The bottom of the bucket body is equipped with chain plate protection (anti-abrasive wear cycle> 5000 hours)
Low-density sand and gravel
Lightweight module enabled (carbon fiber components accounted for 40%)
Closing speed adjusted to 0.8m/s (30% increase in efficiency)
2. Special environment adaptation
Coastal ports
316L stainless steel substrate (salt spray resistant cycle> 6000 hours)
Galvanized nano coating (5 times higher Cl⁻ corrosion resistance)
Polar mines
Electric heat tracing system (-50°C start-up, heating power 3kW)
Low temperature grease (working temperature: -60°C~100°C)
