The Alligator Shear, also known as the Crocodile Shear, is a hydraulic-powered metal cutting machine designed for cold-shearing various metal profiles, including steel plates, rods, angle iron, and scrap vehicles. Its name derives from its jaw-like structure, mimicking the powerful bite of a crocodile. Widely used in metal recycling yards, automotive dismantling sites, and steel mills, this machine combines rugged construction with precision engineering to deliver efficient, cost-effective material processing.
Motor version of the metal shear operation use
This crocodile shearing machine can be operated continuously automatically or manually in a single operation, making it a good processing equipment for cutting heavy waste, light and thin furnace materials, and steel bars.

The crocodile type shearing machine is an efficient and powerful metal shearing equipment, mainly used in the recycling industry of waste materials, steel, non-ferrous metals, and other metal processing industries. Its design inspiration comes from the mouth of crocodiles, which simulate the biting action of crocodiles to achieve cutting of metal materials.
Key Features
Hydraulic Drive System
- Powered by a hydraulic pump, the machine generates forces ranging from 63 to 400 tons, enabling it to shear through thick metal sections with minimal noise and vibration.
- Compared to mechanical systems, hydraulic drives offer smoother operation, easier maintenance, and built-in overload protection.
Adjustable Blade Length and Force
- Blade lengths span 400mm to 1,500mm, accommodating materials from rebar to large I-beams.
- Models like the Q43-1000 deliver 1,000 kN of force, cutting 600mm-wide steel plates at 6–12 strokes per minute.
Portable and Versatile Design
- Compact units (e.g., 6,500kg weight) require no fixed foundation, making them ideal for mobile recycling operations.
- Diesel-engine options allow operation in remote areas without electricity.
Safety and Durability
- Equipped with emergency stop buttons, guard fences, and automatic overload shutdown.
- Hardened steel blades resist wear, while lubrication systems ensure longevity.

What is the working principle of the crocodile type shearing machine
The alligator-style shear machine achieves efficient cutting through a hydraulic drive system: the motor drives the hydraulic pump to generate high-pressure oil, which pushes the cylinder piston to move back and forth, causing the moving blade frame to close toward the fixed blade frame in an “alligator jaw opening and closing” manner. When metal materials are fed into the blade gap, the hydraulic system continuously applies pressure, and the sharp edges of the moving and fixed blades generate immense shearing force, instantly severing the material. Its core advantages include adjustable pressure, overload protection, and low-noise stable operation, making it an ideal cold-cutting tool for applications such as metal recycling and scrap vehicle dismantling.

Industry Status and Development Trends
In the scrap metal recycling industry, alligator-style shearing machines have become the industry standard. According to statistics, China processes over 200 million tons of scrap metal annually, with 70% of the processing workflow relying on shearing machines. As the “dual carbon” goals are advanced, equipment is upgrading toward intelligent and energy-efficient directions:
Fully automatic control: Integrated with a visual recognition system, it automatically identifies material types and adjusts shearing parameters.
Modular design: Core components such as blade holders and cylinders support quick replacement, reducing maintenance time by 60%.
Green manufacturing: Utilizing low-noise hydraulic valves and energy-efficient motors, energy consumption per unit of output is reduced by 15%.

Application scope of crocodile type shearing machine
The Metal Cutting Shears is mainly suitable for various metal waste materials, including but not limited to scrap iron, scrap steel, steel bars, steel pipes, steel plates, angle iron, channel steel, square steel, round steel, and other materials. This equipment can perform cold shear processing on these materials, making them qualified furnace materials or other reused materials. It is also suitable for fixed length cutting of steel profiles in steel mills. It has a wide range of applications, not only suitable for waste recycling stations, metal processing plants, metal dismantling plants, smelting and casting plants, but also suitable for places such as scrap iron recycling stations, steel mills, crushing plants, and automobile dismantling plants.
Metal Recycling
- Process scrap cars, appliances, and structural steel into furnace-ready billets.
- Example: A Q43-200 shear cuts 800mm-wide steel plates into 200mm chunks for smelting.
Automotive Dismantling
- Disassemble vehicle frames by shearing through chassis components and axles.
Steel Mill Operations
- Cut hot-rolled billets or defective products into manageable lengths for reprocessing.

Precautions for Hydraulic Metal Shears
1.Operators: Ensure that they have received professional training and understand the equipment operation and safety regulations.
2.Lubrication and maintenance: Regularly add lubricating oil and butter to maintain the equipment in good condition.
3.Material handling: Avoid cutting prohibited materials and do not use hands to directly contact materials or moving parts of the machine.
4.Safety protection: Wear personal protective equipment and keep away from the transmission and cutting edge.
5.Start and stop: Before starting, ensure that there are no obstacles above the machine. After stopping, wait for it to come to a complete stop before operating.
6.Rainy protection: Avoid working outdoors to ensure safe and dry operation of the machine.
7.Maintenance and repair: Do not repair during work, inspect and maintain after shutdown.
