Hydraulic 13–20 times per minute Alligator Shear for Heavy Scrap Pre-Cutting Before Baling and Furnace Feeding

 Hydraulic 13–20 times per minute Alligator Shear for Heavy Scrap Pre-Cutting Before Baling and Furnace Feeding

Product Overview

The 4000kN Hydraulic Alligator Shear is designed for recycling companies, steel mills, foundries, and metal processing plants that need to pre-cut heavy scrap metal before baling, furnace charging, loading, or resale. In many recycling operations, oversized scrap is not ready for the next processing step. Long steel bars, round steel, rebar, pipes, angle steel, and channel steel often need to be cut into shorter and more manageable pieces before they can be efficiently handled.

This machine provides 4000kN largest shear force, a 550mm blade opening, and a 1200mm blade length, making it suitable for heavier scrap materials than standard alligator shears. It can cut scrap steel up to 90×90mm and round steel up to Φ100mm, depending on material hardness. For customers who work with medium-heavy and heavy ferrous scrap, this model offers a practical solution between small manual cutting equipment and large automatic shearing lines.

The machine is especially useful when the customer already has a metal baler, furnace, truck loading area, or scrap sorting line. By cutting long and irregular scrap into shorter pieces, the 4000kN alligator shear helps improve feeding efficiency, reduce material blocking, increase loading density, and make the whole recycling workflow smoother.

With manual feeding and optional manual or PLC semi-automatic operation, the machine gives buyers flexibility based on their labor conditions, site layout, and production habits. The 44kW motor provides stable hydraulic power, while the cutting frequency of 13–20 times per minute supports continuous cutting work in daily scrap processing.

Cause

In many scrap yards, the most difficult part is not only cutting the material, but making the material suitable for the next process.

Oversized scrap often causes several problems:

Long steel bars are difficult to load into a metal baler.

Irregular scrap may reduce bale density and affect bale shape.

Large pieces are inconvenient for furnace feeding.

Truck and container loading space is not fully used.

Manual gas cutting slows down the whole yard operation.

Workers spend too much time preparing scrap before processing.

Smaller alligator shears cannot cut thicker bars or heavy profiles.

When the pre-cutting process is inefficient, downstream equipment cannot perform at its best. A metal baler may require more feeding time. A furnace may need more preparation before charging. A truck may carry less scrap because the material is too irregular. These hidden costs can reduce the overall profit of the recycling business.

Solution

The 4000kN Hydraulic Alligator Shear helps customers solve the problem from the beginning of the workflow. Instead of sending oversized scrap directly to the next process, the machine first cuts the material into shorter and more suitable lengths.

The 4000kN shear force gives the machine enough power to cut thick ferrous scrap. The 550mm blade opening allows operators to feed larger or irregular materials more easily. The 1200mm blade length helps handle longer contact areas and improves cutting flexibility for different scrap shapes.

This machine can help customers:

Prepare long scrap before feeding into a metal baler.

Cut heavy steel bars before furnace charging.

Reduce oversized scrap before truck or container loading.

Improve material stacking and yard management.

Reduce dependence on manual flame cutting.

Make scrap size more uniform for resale or further processing.

Improve the working efficiency of downstream equipment.

For many buyers, this model is not simply a cutting machine. It is a pre-processing solution that helps connect scrap receiving, cutting, baling, loading, melting, and resale into a smoother production flow.

Specifications

Application

The 4000kN Alligator Shear is suitable for scrap pre-processing in different industrial environments.

It can be used in:

Scrap metal recycling yards

Steel mills and foundries

Metal processing workshops

Construction and demolition scrap recovery sites

Steel bar and round bar cutting operations

Pre-cutting before hydraulic metal baling

Pre-cutting before furnace charging

Truck and container loading preparation

Scrap sorting and resale preparation

For recycling yards, the machine helps turn long and irregular scrap into shorter pieces that are easier to stack and sell. For foundries and steel mills, it helps prepare furnace-ready scrap with more suitable sizes. For customers using metal balers, it helps improve feeding efficiency and reduce the difficulty of loading long scrap into the compression chamber.

This makes the machine especially valuable for customers who want to improve their existing scrap processing line without investing in a much larger gantry shear or container shear.

How It Works

The machine uses a hydraulic system to provide strong and stable cutting power. The operator places the scrap material into the blade opening manually. The holding device presses the material to keep it stable during cutting. Then the hydraulic cylinder drives the upper blade downward to cut the material against the lower blade. After the cut is completed, the blade returns for the next cycle.

The working process is simple:

Feed the scrap material into the cutting area.

The holding system fixes the material position.

The hydraulic cylinder drives the blade downward.

The blade cuts the scrap into shorter pieces.

The blade returns and prepares for the next cut.

Operators can choose manual control for flexible cutting work, or PLC semi-automatic operation for more convenient repeated cutting. This flexibility allows customers to select the most suitable operation mode according to their labor skill level and production needs.

How To Choose

The 4000kN Alligator Shear is suitable for customers who need stronger cutting power than standard small alligator shears, but do not require a large automatic shearing line.

Choose this model if your materials include:

Square steel up to 90×90mm

Round steel up to Φ100mm

Thick rebar and steel bars

Heavy angle steel and channel steel

Long steel pipes and profiles

Mixed ferrous scrap before baling or furnace feeding

If your materials are lighter, a smaller alligator shear may be more economical. If your materials include very large H-beams, thick steel plates, or high-volume heavy scrap, a gantry shear or container shear may be more suitable.

Before choosing the model, buyers should consider material size, material hardness, daily working hours, expected output, feeding method, and the equipment used after cutting. Our engineers can recommend a suitable model according to your real scrap type and site conditions.

FAQ

1. Why is pre-cutting important before using a metal baler?

Pre-cutting makes long scrap shorter and easier to feed into the baler chamber. This can reduce feeding difficulty, improve working efficiency, and help the baler produce more regular bales.

2. Can this machine be used before furnace feeding?

Yes. The 4000kN Alligator Shear can cut long steel scrap into shorter pieces, making the material easier to handle and more suitable for furnace charging. This is useful for steel mills and foundries.

3. What is the cutting capacity of this machine?

The machine can cut scrap steel up to around 90×90mm and round steel up to Φ100mm, depending on material hardness and actual working conditions.

4. Should I choose manual operation or PLC semi-automatic operation?

Manual operation is suitable for flexible cutting and lower investment. PLC semi-automatic operation is more convenient for repeated cutting work and can help improve operating efficiency. The choice depends on your labor conditions and production requirements.

5. Is this model suitable for very large scrap beams or thick steel plates?

This model is suitable for medium-heavy and heavy scrap within its cutting capacity. If your main materials are very large beams, thick plates, or high-volume heavy scrap, a gantry shear or container shear may be a better choice.
