Hydraulic 4000kN Heavy Duty Alligator Shear with 1200mm Blade for Oversized Scrap Steel Cutting

Product Overview

The 4000kN Heavy Duty Alligator Shear is designed for recycling yards and metal processing companies that handle larger, thicker and more difficult scrap steel every day. With 4000kN shear force, a 550mm blade opening, a 1200mm blade length and 44kW motor power, this machine is built for heavy-duty scrap cutting applications where smaller alligator shears cannot provide enough cutting strength.

This model is suitable for processing heavy scrap steel, thick rebar, round steel, steel bars, angle steel, channel steel, pipe sections, metal profiles and industrial offcuts. It can cut scrap sizes up to 90×90mm or Φ100mm, making it a strong choice for buyers who need a reliable machine for tougher scrap materials. For recycling companies that want to improve scrap value before resale, melting or transportation, this hydraulic scrap metal shear can help turn oversized waste metal into cleaner, shorter and easier-to-sell material.

Compared with light-duty cutting equipment, this machine focuses on high cutting force, wider material adaptability and long-term yard productivity. The large blade opening makes it easier to feed bulky scrap, while the 1200mm blade length provides a wider cutting area for irregular materials. The machine supports manual feeding and offers manual or PLC semi-automatic operation, allowing customers to balance budget, labor habits and production efficiency.

For buyers who process heavy scrap but do not need a complete gantry shear line, this heavy duty alligator shear offers a practical and cost-effective middle solution.

Cause

In scrap metal recycling, not all materials have the same value after collection. Long, oversized and irregular scrap can be difficult to sort, load, sell or feed into downstream equipment. Heavy steel bars, large round steel and thick profiles may slow down the entire yard workflow if they are not cut into manageable sizes.

When scrap remains too large, it often creates several problems:

• It occupies more storage space in the yard
• It reduces truck and container loading efficiency
• It increases handling difficulty for workers and machines
• It may not meet the preferred size for melting or resale
• It can slow down baling, furnace feeding or further processing

For companies handling heavier scrap, a smaller shear may struggle, cut slowly or require repeated positioning. A stronger 4000kN alligator shear helps solve this problem by offering greater cutting capacity and more stable performance for demanding scrap applications.

Solution

This 4000kN hydraulic alligator shear is a strong solution for recycling yards that want to process larger scrap more efficiently and improve the quality of prepared material.

Main advantages include:

• 4000kN powerful shear force for heavy scrap steel cutting
• 550mm blade opening for easier feeding of bulky materials
• 1200mm blade length for wider cutting coverage
• Cuts up to 90×90mm steel scrap or Φ100mm round steel
• 13–20 cuts per minute for efficient daily yard processing
• 44kW motor power for stable heavy-duty operation
• Manual feeding for flexible scrap handling
• Manual or PLC semi-automatic control available
• Suitable for recycling yards, foundries and steel processing sites
• Helps prepare scrap for resale, transportation, baling or melting

By cutting large scrap into shorter and more uniform pieces, this machine helps customers improve material circulation, reduce storage pressure and increase the commercial value of processed scrap.

Specifications

Application

The 4000kN Heavy Duty Alligator Shear is suitable for customers who regularly process large and heavy scrap metal. It is widely used in:

• Scrap metal recycling yards
• Steel mills and foundries
• Metal trading companies
• Demolition scrap recovery sites
• Machinery manufacturing plants
• Industrial scrap processing centers
• Steel bar and round steel cutting workshops
• Furnace charge material preparation sites

Typical materials include:

• Thick rebar
• Round steel
• Steel bars
• Angle steel
• Channel steel
• Steel pipes
• Heavy metal profiles
• Demolition scrap
• Industrial steel offcuts
• Mixed heavy scrap steel

This machine is especially suitable for yards that need stronger cutting ability than Q43-1600 or Q43-2000 models, but still want a machine that is simpler and more economical than a full gantry shear system.

How It Works

The operator manually places the scrap material into the cutting area. The holding system presses the material and keeps it stable before cutting. The hydraulic system then drives the blade downward, using strong shear force to cut the material into shorter sections.

Manual operation is suitable for customers who prefer simple control and lower investment. PLC semi-automatic operation is suitable for buyers who want easier repeated cutting and more consistent working rhythm. The machine can operate independently, making it flexible for recycling yards with different site layouts.

Because of its strong hydraulic structure and large blade opening, this model is especially useful when processing irregular scrap that is difficult to cut with smaller machines.

How To Choose

Buyers should choose this model when their scrap material is beyond the capacity of small and medium alligator shears.

1. Choose this model for heavy scrap cutting
   If your material includes thick steel bars, large round steel, heavy profiles or demolition scrap, the 4000kN model provides stronger cutting ability.
2. Choose it when Q43-2000 or Q43-2500 is not enough
   This model is suitable for materials up to 90×90mm / Φ100mm, offering a clear upgrade in cutting capacity.
3. Choose PLC operation for frequent daily use
   If your yard cuts scrap every day, PLC semi-automatic control can make operation easier and more consistent.
4. Choose manual control for simple and economical operation
   Manual control is suitable for customers who want lower cost and easier maintenance.
5. Confirm material hardness before final selection
   Cutting capacity depends not only on size but also on material hardness. For harder alloy steel or special materials, model selection should be confirmed with factory engineers.

FAQ

1. What type of scrap is this 4000kN alligator shear suitable for?

It is suitable for heavy scrap steel, thick rebar, round steel, steel bars, angle steel, channel steel, steel pipes, profiles and industrial offcuts. The recommended cutting capacity is 90×90mm or Φ100mm, depending on material hardness.

2. Is this machine better than a smaller alligator shear?

Yes, if your scrap is larger or harder. The 4000kN model provides stronger cutting force, larger blade opening and longer blade length, making it more suitable for heavy-duty scrap metal cutting.

3. Can this machine improve scrap resale value?

In many cases, yes. Cutting oversized scrap into shorter and cleaner pieces makes the material easier to load, transport, sort and process. This can help improve handling efficiency and make scrap more attractive for downstream buyers.

4. Does this machine require automatic feeding equipment?

No. This model uses manual feeding, which is simple and flexible for irregular scrap. If the customer has special layout requirements, feeding support or customized handling solutions can be discussed.

5. Can the control system be customized?

Yes. The machine can be supplied with manual control or PLC semi-automatic control. Voltage, machine color, blade material and other details can also be customized according to the customer’s working site.
