Industrial 4000kN Alligator Shear for Cutting 90×90mm Scrap Steel and Φ100mm Round Bar

Industrial 4000kN Alligator Shear for Cutting 90×90mm Scrap Steel and Φ100mm Round Bar

The 4000kN Hydraulic Alligator Shear is a heavy-duty scrap metal cutting machine designed for recycling yards, steel mills, foundries, metal processing plants, and industrial scrap handling sites that need stronger cutting capacity for medium-heavy and heavy ferrous materials. With a 4000kN largest shear force, 550mm blade opening, and 1200mm blade length, this alligator shear is suitable for cutting thicker steel scrap, including steel bars, round bars, rebar, steel pipes, angle steel, channel steel, and mixed industrial scrap.

Compared with smaller alligator shears, this model is built for customers who process heavier materials and require higher cutting stability. It can cut scrap steel up to 90×90mm and round steel up to Φ100mm, depending on material hardness. The larger blade opening allows easier feeding of irregular and bulky scrap, while the longer blade length provides a wider cutting range for different material shapes.

For recycling companies, oversized scrap often causes problems in storage, loading, baling, and furnace feeding. Long and thick steel pieces take up more space, reduce truck or container loading density, and slow down daily operations. This 4000kN alligator shear helps reduce large scrap into shorter and more manageable sizes, improving the whole scrap processing workflow.

The machine supports manual feeding and can be equipped with manual or PLC semi-automatic operation, giving buyers flexibility according to their labor conditions, budget, and production requirements. With a 44kW motor and cutting frequency of 13–20 times per minute, it provides strong and efficient cutting performance for continuous recycling work.

Cause

Many scrap recycling yards and steel processing plants face a common challenge: incoming scrap is becoming heavier, longer, and more irregular. Materials such as thick round bars, heavy rebar, steel profiles, pipes, and mixed construction scrap are difficult to process with light-duty cutting machines.

If these materials are not cut properly, several problems may appear:

Large scrap occupies too much yard space.

Long steel pieces are difficult to load into trucks or containers.

Oversized materials cannot be easily fed into metal balers or furnaces.

Manual gas cutting is slow, labor-intensive, and costly.

Smaller shears may not have enough force for thick steel materials.

Irregular scrap reduces handling efficiency and increases operating pressure.

For customers who need more cutting power but do not want to invest in a large gantry shear or container shear, a heavy-duty alligator shear becomes a practical and economical choice.

Solution

The 4000kN Hydraulic Alligator Shear is designed to solve these problems by combining strong cutting force, large feeding opening, and simple operation in one machine.

The 4000kN shear force provides strong cutting power for thicker scrap steel. The 550mm blade opening makes it easier to place bulky or irregular materials into the cutting area. The 1200mm blade length increases the cutting range and helps operators handle different shapes of scrap more efficiently.

The machine can cut materials such as 90×90mm square steel and Φ100mm round steel, making it suitable for recycling yards that regularly process heavier scrap than standard alligator shears can handle. Its 45kN holding force helps stabilize the material during cutting, improving cutting safety and reducing material movement.

For daily production, the machine helps customers:

Cut long scrap into shorter pieces.

Improve yard storage and material turnover.

Prepare scrap before baling or furnace feeding.

Reduce dependence on manual gas cutting.

Improve loading efficiency for trucks and containers.

Handle thicker and heavier ferrous scrap with better stability.

This makes the machine a strong solution for customers who need more power, but still want a compact and flexible cutting machine.

Specifications

Application

The 4000kN Alligator Shear is suitable for customers who need to cut medium-heavy and heavy scrap metal before storage, transportation, baling, melting, or resale. It can be widely used in:

Scrap metal recycling yards

Steel mills and foundries

Metal processing workshops

Construction and demolition scrap recovery

Steel bar and round bar cutting

Rebar, pipe, angle steel, and channel steel processing

Pre-cutting before metal baling

Pre-cutting before furnace charging

Truck and container loading preparation

For recycling yards, the machine helps reduce oversized scrap into shorter pieces, making the yard cleaner and easier to manage. For foundries and steel mills, it helps prepare furnace-ready scrap with more suitable feeding sizes. For metal processing plants, it can cut leftover steel profiles and production waste into reusable or sellable materials.

How It Works

The machine uses hydraulic power to drive the cutting blade. The operator manually places the scrap metal into the blade opening. The holding device presses the material to keep it stable, and then the hydraulic cylinder drives the upper blade downward to complete the cutting action. After cutting, the blade returns for the next cycle.

The basic working process is:

Place the scrap material into the cutting area.

The holding device presses and stabilizes the material.

The hydraulic system drives the blade downward.

The blade cuts the material against the lower blade.

The blade returns automatically for the next cutting cycle.

The operation is simple and suitable for repeated cutting work. Customers can choose manual control or PLC semi-automatic control according to their production habits and operation requirements.

How To Choose

When choosing an alligator shear, buyers should consider the actual material size, material hardness, daily processing volume, operation method, and future production needs.

Choose this 4000kN Alligator Shear if your materials include:

Square steel up to 90×90mm

Round steel up to Φ100mm

Thicker rebar and steel profiles

Medium-heavy and heavy ferrous scrap

Long steel pipes, angle steel, and channel steel

Mixed scrap that requires stronger cutting force

If your materials are smaller, a 1600kN or 2500kN alligator shear may be enough. If your materials are much larger, such as heavy beams, thick plates, or high-volume scrap, a gantry shear or container shear may be more suitable.

For customers processing harder steel, blade material can be upgraded according to actual material conditions. Our engineers can recommend the proper machine model and blade solution based on your scrap size, material type, working capacity, and site layout.

FAQ

1. What is the main advantage of the 4000kN Alligator Shear?

The main advantage is its stronger cutting capacity. With 4000kN shear force, 550mm blade opening, and 1200mm blade length, it can process thicker and heavier scrap steel than smaller alligator shears.

2. What materials can this machine cut?

This machine can cut scrap steel, round bar, rebar, steel pipe, angle steel, channel steel, and mixed ferrous scrap. Its cutting capacity can reach around 90×90mm square steel and Φ100mm round steel, depending on material hardness.

3. Can this machine be equipped with PLC control?

Yes. The machine can be operated manually or equipped with PLC semi-automatic control according to customer requirements. PLC semi-automatic operation can make daily cutting work easier and more efficient.

4. Is this machine suitable before using a metal baler?

Yes. This alligator shear is suitable for pre-cutting long and heavy scrap before feeding it into a metal baler. Shorter scrap pieces are easier to load into the baler chamber and can improve overall baling efficiency.

5. How do I know whether I should choose this model or a larger shear?

If your main material is within 90×90mm square steel or Φ100mm round steel, this model is usually a practical choice. If your scrap includes very large beams, thick steel plates, or requires high-capacity automatic cutting, we can recommend a gantry shear or container shear based on your project needs.
