Hydraulic 3150 kN Alligator Shear for Heavy Scrap Metal Cutting

Product Overview

The Q43-3150 Alligator Shear is a heavy-duty hydraulic scrap metal shear designed for cutting thick and oversized metal into smaller, manageable pieces. With a maximum shearing force of 3150 kN, a 1200 mm blade and a cutting frequency of 12–20 times per minute, it provides an efficient solution for scrap yards, metal recycling plants, foundries and steel processing facilities.

The machine can cut square steel up to 70 × 70 mm and round steel up to Φ80 mm, depending on material strength and feeding conditions. Its 630 kN hydraulic hold-down system firmly presses the material before cutting, reducing movement and helping achieve stable, consistent cuts.

Manual feeding makes the Q43-3150 flexible for mixed and irregular scrap. Buyers can select manual control or PLC semi-automatic operation according to their production requirements, operator experience and budget.

Cause

Oversized scrap metal creates several problems for recycling operations:

• Long steel bars and profiles are difficult to transport and store
• Irregular scrap occupies excessive yard and container space
• Large materials cannot be fed directly into furnaces or downstream equipment
• Flame cutting requires more labor and may produce smoke, sparks and higher operating costs
• Unstable materials can move during cutting and affect safety and cutting accuracy

Without a suitable scrap metal cutting machine, these issues can reduce processing efficiency and increase labor and handling expenses.

Solution

The Q43-3150 hydraulic alligator shear converts bulky scrap into uniform, furnace-ready pieces through powerful hydraulic cutting. Its 3150 kN shear force is suitable for demanding materials, while the 1200 mm blade allows several smaller pieces or one wider workpiece to be processed in a single cutting area.

A 630 kN holding force secures the scrap before the blade moves downward. This improves cutting stability, reduces material bouncing and helps protect the operator. The 44 kW motor provides a practical balance between strong cutting performance and energy consumption.

Key advantages include:

• Heavy-duty cutting capacity for thick scrap metal
• 12–20 cutting cycles per minute for efficient processing
• Strong hold-down system for stable material positioning
• Manual or PLC semi-automatic control options
• Simple feeding and flexible handling of mixed scrap
• Reduced dependence on flame cutting and manual dismantling
• Easier maintenance than more complex continuous shearing systems

Specifications

Actual cutting capacity may vary according to the material grade, tensile strength, shape, feeding position and blade condition.

Application

The Q43-3150 scrap metal shear can process various ferrous and non-ferrous metal materials, including:

• Round steel, square steel and flat steel
• Steel bars, pipes, angles and channels
• Rebar and construction scrap
• Light steel structures and fabricated offcuts
• Vehicle dismantling scrap
• Mixed industrial metal waste
• Furnace charge preparation materials

It is widely used in scrap recycling yards, steel mills, foundries, metal trading companies, demolition recycling operations and industrial waste processing centers.

How It Works

The operator places the scrap onto the feeding area and moves it to the required cutting position. After the cutting command is activated, the hydraulic hold-down device presses and stabilizes the material. The main hydraulic cylinder then drives the upper blade downward to complete the cut.

The blade returns automatically after each cutting cycle. Under PLC semi-automatic operation, selected movements can follow a preset sequence, helping improve cycle consistency while retaining the flexibility of manual feeding.

How To Choose

Choose the Q43-3150 when your materials include square steel up to 70 × 70 mm, round steel up to Φ80 mm or similarly demanding scrap sections. Before confirming the model, provide the following information:

• Material type and maximum dimensions
• Material grade or tensile strength
• Required finished cutting length
• Expected daily or hourly capacity
• Local voltage and frequency
• Preferred manual or PLC semi-automatic control

For larger solid steel, higher-strength alloy materials or greater production capacity, a higher-force shear may be more appropriate.

FAQ

What materials can the Q43-3150 cut?

It is suitable for round steel, square steel, rebar, profiles, pipes and mixed industrial scrap. The exact capacity depends on the material’s strength, shape and feeding position.

Can it cut 70 × 70 mm square steel and Φ80 mm round steel?

Yes, these are the stated maximum reference sizes under suitable material and operating conditions. Please provide the steel grade for final technical confirmation.

Is the machine fully automatic?

No. Material feeding is manual, while the machine can be configured with manual control or PLC semi-automatic operation.

How often do the blades need replacement?

Blade life depends on the processed material, operating hours and maintenance. The blades can normally be rotated or reground before replacement, depending on their design and wear condition.

Can the voltage and machine configuration be customized?

Yes. The electrical system, voltage, frequency, control mode, safety protection and selected auxiliary equipment can be customized according to the buyer’s local requirements.
