Metal Shear for Excavator Structure and Working Principle
Single-cylinder and double-cylinder hydraulic shears differ significantly in structure and working principles, which directly affect their application scenarios and performance.
Structural Design
- Single-cylinder hydraulic shears have a simpler design consisting of one cylinder and one hydraulic ram, making them lighter and more compact.
- Double-cylinder hydraulic shears include two cylinders and one oil reservoir. Their dual hydraulic cylinders generate greater pressure, making them suitable for heavy-duty cutting tasks.
Working Principle
- Single-cylinder hydraulic shears cut by extending or retracting the piston in the hydraulic cylinder.
- Double-cylinder hydraulic shears are driven by a hydraulic system that activates pistons in the upper and lower cylinders, pushing the shear arms together. This dual-cylinder mechanism provides more uniform cutting force and greater stability.
Performance Characteristics
- Double-cylinder shears provide greater compression force, ideal for cutting harder metal materials.
- Single-cylinder shears are suitable for cutting small and lightweight metal materials.
Understanding these differences helps users choose the most suitable metal shear for excavator.
Single-Cylinder Hydraulic Shears
As one type of hydraulic metal shears for excavator, single-cylinder hydraulic shears excel in specific application scenarios.
Wide Applicability
They are ideal for dismantling motorcycles, vans, agricultural machinery, wheel hub separation, and other vehicle processing. They efficiently compress and reduce scrap steel and are suitable for building demolition and steel cutting tasks—making them excellent for light to medium-duty operations.
Advanced Technical Features
- Manufactured with Swedish Hardox500 steel, ensuring lightweight construction with superior wear resistance.
- Pins made from 42CrMo alloy steel with built-in oil passages for high strength and good toughness.
- Equipped with Swiss-imported rotary motors, offering full-angle rotation for enhanced operational flexibility.
Efficient Hydraulic System
- Cylinders use honed tubes with imported NOK seals, ensuring short working cycles and long service life.
- Blades made from wear-resistant alloy steel, resistant to high temperatures and deformation.
Double-Cylinder Hydraulic Shears
For more demanding industrial environments, double-cylinder hydraulic shears provide powerful cutting capacity and stability, making them the ideal heavy-duty metal shear for excavator.
Strong Applicability
Designed for cutting steel frames and vehicle beams, and excellent for dismantling scrap cars and metal products. Their high cutting force easily handles the toughest metal materials.
Advanced Technical Features
- Equipped with Swiss-imported rotary motors for full-angle rotation.
- Cylinders use honed tubes and imported NOK seals.
- Blades made from wear-resistant alloy steel to withstand high-intensity continuous operations.
Outstanding Performance Advantages
Dual cylinders deliver greater compression force and more uniform cutting power, reducing equipment strain and extending service life. These hydraulic metal shears for excavator are built for the most demanding tasks.
Metal Shear for Excavator Safety Operation Guide
Comprehensive Pre-Operation Inspection
Before starting any metal shear attachment for excavator, operators must conduct a thorough inspection:
- Ensure hydraulic lines are secure and leak-free.
- Check pins, blades, and critical parts for cracks or excessive wear.
- Ensure no debris remains in the blade gap.
Follow On-Site Safety Regulations
- Clearly mark the working area and keep unrelated personnel away.
- During crushing or cutting, operators must watch for flying metal fragments.
Never Exceed Performance Limits
Every excavator metal shear for sale has a rated maximum cutting capacity. Operators must never attempt to cut materials beyond the equipment’s limits, as overload may cause structural damage or hydraulic failure.
