Q43-4000 Heavy-Duty Hydraulic Alligator Shear with 4000 kN Shearing Force and Ø100 mm Steel Cutting Capacity for Structural Scrap Processing

The Q43-4000 Hydraulic Alligator Shear is a high-capacity heavy scrap cutting machine designed for processing large-section steel materials in professional recycling yards, steel stockholders, and industrial scrap preparation facilities.

With a 4000 kN shearing force, 1200 mm blade length, and maximum blade opening of 660 mm, this model is specifically engineered for cutting thick structural steel, large square bars, and heavy scrap sections that exceed the capability of standard alligator shears.

Compared with mid-range models, the Q43-4000 prioritizes higher cutting strength, wider opening, and improved material adaptability, making it a reliable solution for demanding heavy-material applications.

Reinforced Alligator Shear Frame
The heavy-duty frame structure is designed to withstand high cutting loads generated when processing thick steel sections.

Wide Opening Blade Design
The 660 mm maximum opening allows easy feeding of bulky and thick materials without excessive pre-cutting.

Dual-Motor Hydraulic Power Unit
The 2 × 30 kW motor configuration ensures stable hydraulic output and consistent cutting force under heavy loads.

Precision Blade Alignment
Optimized blade geometry ensures clean cuts and reduces blade wear during thick-section cutting.

High-Strength Cutting Capability
Capable of cutting round steel up to Ø100 mm and square steel up to 90 × 90 mm reliably.

Stable Heavy-Load Operation
Designed for continuous cutting of heavy scrap without power fluctuation.

Reduced Material Preparation Time
Wide blade opening minimizes the need for pre-processing large scrap pieces.

The Q43-4000 Hydraulic Alligator Shear is ideal for:

• Structural steel offcuts

• Heavy steel bars and profiles

• Thick square and round steel scrap

• Scrap preparation before baling or melting

It is particularly suitable for facilities handling medium-to-large heavy steel volumes where higher cutting force is required.

Suitable Materials

• Thick steel bars and profiles within rated dimensions

• Prepared heavy scrap metal

• Carbon steel and low-alloy steel

Not Recommended For

• Large loose scrap piles without preparation

• Continuous bulk scrap feeding

• Extremely large or mixed scrap better handled by container or gantry shears

• Q43-2500 → Heavy daily cutting

• Q43-3150 → Extra-heavy thick-section cutting

• Q43-4000 → High-force, wide-opening heavy steel cutting (this model)

• Q43W / Q43L series → Container or gantry shears for continuous large-scale operations
