Why Gantry Scrap Metal Shears Dominate Heavy-Duty Recycling: A Technical Breakdown

Introduction
In scrap metal recycling, choosing the right shear is critical for efficiency and ROI. While inclined shears and shear balers (side compression) have their uses, gantry-type scrap metal shears offer unmatched advantages for heavy-duty operations. Here’s why industry leaders like DL Industry Group prioritize gantry technology.

Superior Advantages of Gantry scrap metal shears

1. Unmatched Shearing Power & Blade Width

   • Shearing Force: 350T–2500T (vs. 400T–2000T for alternatives).
   • Blade Width: Up to 3000mm (vs. 800–1600mm for shear balers/inclined shears).
   • Impact: Cuts thicker materials (steel beams, industrial scrap) in a single pass.

2. Highest Production Rates

   • Output: 50–180 tons/hour (vs. 10–150 tons/hour for alternatives).
   • Efficiency: Processes bulky scrap faster due to wider blades and no pre-compression stage.

3. Durability & Low Maintenance

   • Frame: S45C steel (600MPa tensile strength), 160% stronger than standard Q235 steel.
   • Blades: X45 hardened steel (58–60 HRC), 150% harder than standard H13 blades.
   • Tank Plates: HARDOX550 (550HBW), 250% harder than standard materials.

4. Energy Efficiency

   • Servo Motors: Save 50–70% power vs. conventional motors.
   • Example: A 1250T gantry shear uses 182 KW, while competitors require 270–350 KW.

5. Optimized for High-Density Output

   • Steel Plant Requirement: Chinese mills demand high-density scrap bales to maximize furnace efficiency.
   • Gantry Solution: Delivers loosely sheared scrap ideal for subsequent baling (unlike shear balers, which compromise density).

Key Drawbacks of Inclined Shears & Shear Balers

Inclined Shears: Limited for Heavy Scrap

• Blade Constraints: Narrow blades (max 1400mm) struggle with wide materials.
• Lower Force: Max 1500T shearing force.
• Output Lag: 10–110 tons/hour (30% slower than gantry shears).
• Best For: Continuous processing of smaller, irregular scrap.

Shear Balers (Side Compression): Complexity & Density Trade-offs

• Added Steps: Pre-compression delays shearing, reducing throughput.
• Density Issues: Compressed scrap creates "fluffy" bales unsuitable for steel furnaces.
• Maintenance: Hydraulic side arms increase failure risk.
• Cost: 20–30% pricier than gantry shears with similar force.

Gantry Shears: Engineered for 24/7 Operations

DL Industry Group’s gantry shears include:

• PLC Control: Fully automated with remote operation.
• 0.2-Second Response: Reaches peak speed instantly.
• 20-Second Cycle Time: 3x faster than competitors.
• 2-Year Warranty: Reflects confidence in durability.

Conclusion: The Clear Choice for Heavy-Duty Recycling

Gantry scrap metal shears dominate with their raw power, blade versatility, and cost efficiency. While inclined shears suit niche applications, and shear balers add unnecessary complexity, gantry technology delivers:
✅ Highest output (180 tons/hour)
✅ Lowest operating costs (energy + maintenance)
✅ Perfect scrap density for steel mills

For recyclers processing industrial-scale scrap, gantry shears are the undisputed solution.
