44kW Alligator Shear With1200mm Blade Length For Cutting Metal Materials Up To 90x90mm

44kW Alligator Shear With1200mm Blade Length For Cutting Metal Materials Up To 90x90mm

Product Overview

The Q43-4000 Alligator Shear is a heavy-duty hydraulic scrap metal cutting machine developed for recycling yards, steel mills, foundries, metal-processing plants, and dismantling facilities. With a maximum shearing force of 4000kN, a 1200mm blade, and a maximum blade opening of 550mm, it efficiently reduces long, bulky, and irregular metal scrap into shorter, manageable pieces.

This hydraulic alligator shear can process square steel up to 90 × 90mm and round steel up to Φ100mm, subject to the material grade and actual tensile strength. Its wide blade and large opening make it suitable for cutting steel bars, pipes, profiles, rebars, structural offcuts, and mixed industrial scrap.

The machine completes approximately 13–20 cutting cycles per minute, helping recyclers improve processing efficiency without relying on slow manual cutting methods. A 44kW hydraulic power system delivers stable shearing performance while maintaining practical energy consumption for daily industrial operation.

The Q43-4000 supports manual feeding and can be operated using either manual controls or a PLC semi-automatic system. This configuration provides flexibility for different working conditions. Operators can use manual control when processing irregular scrap or select semi-automatic operation for repetitive cutting tasks.

Its open feeding structure also allows long materials to be placed directly between the blades, eliminating the need to pre-cut oversized scrap before loading.

Cause

Long and irregular scrap metal is difficult to store, transport, sort, and feed into downstream recycling equipment. Steel bars, pipes, profiles, and dismantled structures often occupy excessive space even when their actual weight is relatively low.

Common problems include:

• Long scrap cannot be loaded efficiently into trucks or containers
• Oversized material may not fit into furnaces or metal balers
• Gas cutting requires additional labor, fuel, and safety management
• Irregular scrap is difficult to stack and handle
• Manual processing reduces overall recycling productivity
• Mixed scrap sizes can interrupt downstream production

These challenges increase labor costs and reduce the value and handling efficiency of recyclable metal.

Solution

The Q43-4000 hydraulic alligator shear provides a practical solution by cutting oversized metal scrap into shorter, more uniform pieces. Its 4000kN shearing force handles heavy scrap that smaller cutting machines may struggle to process.

The 550mm blade opening provides enough clearance for bulky and irregular materials, while the 1200mm blade length allows multiple smaller pieces or wider scrap to be processed in one operation.

Key benefits include:

• Powerful 4000kN hydraulic shearing force
• Large 550mm blade opening for bulky scrap
• Wide 1200mm cutting blade
• Fast cutting frequency of 13–20 times per minute
• Manual and PLC semi-automatic operating options
• Open feeding design for long steel materials
• Reduced dependence on flame cutting
• Easier scrap storage, transportation, and furnace feeding
• Simple daily operation and convenient maintenance

Specifications

The actual cutting capacity depends on the material grade, shape, tensile strength, feeding position, and condition of the cutting blades.

Application

The Q43-4000 industrial scrap shear is suitable for:

• Scrap metal recycling yards
• Steel mills and foundries
• Metal fabrication factories
• Automotive dismantling facilities
• Ship dismantling and repair yards
• Construction steel recycling
• Machinery manufacturing plants
• Metal collection and processing centers

Typical materials include round steel, square steel, steel pipes, rebars, angle steel, channel steel, aluminum profiles, light structural scrap, and manufacturing offcuts.

How It Works

The operator places the scrap metal into the open cutting area manually or with suitable material-handling equipment. The material is positioned between the hydraulic hold-down device and the cutting blade.

After the cutting command is activated, the hold-down mechanism stabilizes the material. The hydraulic cylinder then drives the upper blade downward, generating up to 4000kN of shearing force.

Once the material is cut, the blade returns to its original position and the operator advances the remaining scrap for the next cut. Under suitable working conditions, the machine can complete approximately 13–20 cycles per minute.

Manual operation gives the operator greater control when processing irregular materials. PLC semi-automatic operation is more suitable for repetitive cutting and helps maintain a consistent working rhythm.

How To Choose

The correct alligator shear should be selected according to material dimensions, strength, shape, and required hourly output.

The Q43-4000 is a suitable choice when:

• The material includes heavy steel bars, pipes, and structural offcuts
• Round steel diameter is no more than approximately 100mm
• Square steel size is no more than approximately 90 × 90mm
• A 1200mm cutting blade is required
• The scrap is too long for direct baling or furnace feeding
• Manual feeding is suitable for the recycling process
• Manual and semi-automatic controls are both required

Cutting capacity should not be judged only by material dimensions. High-strength alloy steel, hardened steel, bundled scrap, and solid steel may require additional technical evaluation. Buyers should provide material photos, dimensions, grades, and desired production capacity before ordering.

FAQ

What materials can the Q43-4000 Alligator Shear cut?

It is designed for steel bars, steel pipes, rebars, angle steel, channel steel, profiles, manufacturing offcuts, and other long metal scrap. Very hard alloy steel and hardened materials should be technically confirmed before processing.

Can it cut 100mm round steel?

The reference maximum capacity is Φ100mm round steel. Actual cutting performance depends on the steel grade, tensile strength, blade condition, and material position. Please provide the material grade when requesting final confirmation.

What is the difference between manual and PLC semi-automatic operation?

Manual operation allows the operator to control each cutting movement and is suitable for irregular scrap. PLC semi-automatic operation performs selected movements according to a preset sequence, improving efficiency during repetitive cutting.

How is material loaded into the machine?

The standard model uses manual feeding. Long or heavy materials can also be positioned with a crane, grabber, forklift, or other external handling equipment according to the buyer’s working conditions.

How often do the blades need to be replaced?

Blade service life depends on the material hardness, cutting frequency, operating method, and maintenance. Regular blade inspection, correct material positioning, and avoidance of overloaded cutting can significantly extend blade life.
