380mm Alligator Metal Shear 22kw Hydraulic Sheet Metal Shear For Hardware Products

The Q43-2000 Alligator Shear is an efficient and durable stationary cold-cutting machine designed for processing metal scrap. Named for its jaw-like cutting action resembling an alligator's mouth, this model delivers a powerful shearing force of 200 tons. It features robust blades with a length of 1000 mm and a maximum opening of 380 mm, enabling it to easily cut materials such as round steel up to Ø75 mm or square steel up to 65x65 mm at ambient temperature. Driven by a 22 kW motor, the Q43-2000 is known for its compact structure, simple operation, and low maintenance costs. It is an ideal solution for scrap yards, foundries, forging shops, and steel structure fabricators requiring efficient metal sizing and shearing.

• Powerful Cutting Performance: A high shearing force of 200 tons, combined with long blades, ensures clean and efficient cutting of high-strength metals.
• Long Blade Design: The 1000 mm blade length allows for simultaneous cutting of multiple smaller-diameter bars or wider flat steel, enhancing operational flexibility.
• Safe and Reliable Operation: Utilizes an electro-hydraulic control system, typically equipped with two-hand operation buttons or foot pedals, ensuring operator safety by keeping hands away from the danger zone.
• Heavy-Duty Construction: The welded body is made from high-quality steel plates, stress-relieved for enhanced rigidity and impact resistance, guaranteeing long-term stability in tough working conditions.
• Easy Maintenance: The hydraulic system and easily wearable parts like blades are designed for straightforward inspection, replacement, and maintenance, minimizing downtime and costs.
• High Return on Investment: As a fundamental yet powerful shearing solution, it offers a relatively low initial investment while significantly improving scrap processing efficiency.

• Metal Recycling Industry: For shearing scrap steel, iron, rebar, and steel sections to facilitate sorting, transportation, and melting.
• Foundry Industry: For cutting raw materials like pig iron and scrap steel into suitable charge sizes.
• Forging Industry: For bar stock cropping and preparation.
• Steel Structure Fabrication & Installation: For cutting angles, channels, round bars, and other profiles.
• Construction & Demolition: For processing waste rebar and steel remnants on-site.

Q1: What is the difference between an Alligator Shear and a Guillotine Shear?

A1: An Alligator Shear has a side-opening jaw that moves up and down, ideal for cutting long bars, profiles, and medium-sized scrap. A Guillotine (or Box) Shear features a vertically moving blade inside a fixed chamber, better suited for compressing and slicing large, tangled scrap like car bodies into smaller pieces. They serve different primary applications.

Q2: Can this shear cut rebar (deformed steel bar)?

A2: Absolutely. The Q43-2000 is perfectly suited for cutting scrap rebar. Its powerful force can easily shear common grades like HRB400, making it ideal for construction sites and recycling centers.

Q3: What happens when the blades become dull? Do we need to replace the whole machine?

A3: No, the entire machine does not need replacement. The blades are replaceable components made from high-strength alloy tool steel. When the cutting edge wears down or chips, they can be disassembled, re-sharpened, or replaced by a technician—a simple and cost-effective process.

Q4: What are the installation requirements?

A4: It must be installed on a solid, level concrete foundation and securely anchored with bolts. A stable power supply meeting the requirements of the 22 kW motor is essential. The hydraulic system must be filled with the correct type and amount of hydraulic oil as specified.
