4000kN Hydraulic Alligator Shear Machine 1200mm Blade Heavy Scrap Cutting For Rebar And Industrial Metal Recycling

Product Overview

The 4000 kN hydraulic alligator shear is a high-performance metal cutting solution designed for demanding scrap processing environments. Built for strength, precision, and long-term durability, this machine is ideal for cutting heavy steel scrap, rebar bundles, pipes, profiles, and mixed ferrous materials. With a powerful 4000 kN shear force and a robust 1200 mm blade length, it delivers consistent cutting performance even under continuous industrial workloads.

This model is engineered for flexibility, offering both manual feeding and optional PLC semi-automatic operation. It is particularly suitable for scrap yards, steel mills, recycling centers, and metal processing workshops that require reliable and efficient size reduction before further processing such as baling or smelting.

Key highlights include high cutting efficiency (13–20 cuts per minute), large blade opening (550 mm), and optimized hydraulic system design, ensuring stable operation, reduced wear, and extended service life.

Cause

In many scrap processing facilities, operators face several challenges:

• Oversized scrap materials that are difficult to handle or transport
• Inefficient cutting methods leading to low productivity
• High labor intensity and safety concerns during manual cutting
• Inconsistent cutting results affecting downstream processes

Traditional cutting tools often fail to deliver the required force and precision, especially when dealing with high-strength steel or irregular scrap shapes.

Solution

This 4000 kN hydraulic alligator shear addresses these issues with a combination of power, control, and reliability:

• Strong shear force ensures clean cutting of thick and dense materials
• Wide blade opening accommodates larger scrap sizes
• High cutting frequency improves overall processing efficiency
• Optional PLC control reduces manual intervention and enhances safety
• Durable blade material (e.g., H13) supports repeated regrinding and long service life

The result is a more efficient, safer, and cost-effective scrap processing workflow.

Application

This machine is widely used across various industries:

• Scrap metal recycling plants
• Steel mills and foundries
• Demolition and construction waste processing
• Automotive scrap recycling
• Metal fabrication workshops

It is suitable for cutting:

• Reinforced steel bars (rebar)
• Steel pipes and tubes
• Structural steel profiles
• Mixed heavy scrap metal

How It Works

The hydraulic alligator shear operates using a powerful hydraulic cylinder that drives the moving blade against a fixed blade. Scrap material is placed between the blades, and as the cylinder actuates, the material is cut with high force.

The holding force stabilizes the material during cutting, ensuring precision and reducing blade wear. Depending on the configuration, the machine can be operated manually or through a PLC system, allowing for semi-automatic cycles and improved operational efficiency.

How To Choose

When selecting a suitable alligator shear, consider the following factors:

• Material type: hardness, thickness, and shape of scrap
• Required throughput: hourly processing capacity
• Maximum scrap size: determines blade opening and length
• Operation preference: manual vs. PLC semi-automatic
• Power supply: local voltage and frequency requirements

For heavier and larger scrap materials, a higher shear force and longer blade length are essential, making this 4000 kN model a strong candidate.

FAQ

Q1: What materials can this machine handle?
A: It is designed for ferrous metals such as steel bars, pipes, profiles, and heavy mixed scrap.

Q2: Can the machine be customized?
A: Yes, parameters such as voltage, control system (PLC), and certain structural aspects can be customized based on your requirements.

Q3: What is the blade lifespan?
A: With proper maintenance, the blade can typically process 6000–10000 tons of material and can be reground multiple times.

Q4: Is PLC control necessary?
A: Not mandatory. Manual operation is available, but PLC semi-automatic control improves efficiency and safety.

Q5: What kind of maintenance is required?
A: Regular hydraulic oil checks, blade inspection, and lubrication are recommended to ensure long-term stable performance.
