Metal shears are key pieces of equipment in the metal recycling industry, used to shear, cut, and process scrap metal for recycling and reuse. Metal shearing machines typically have powerful cutting capabilities and are capable of handling metal materials of all shapes and sizes, including steel, aluminum, and copper.
Among the three main types of metal shears are alligator cutting machines, tiger head shearing machines, and large gantry shearing machines. What they all have in common is that they are specialized in metal shearing and have the ability to cut efficiently and accurately.
Differences between the three types of metal shears
Alligator Shear: It is known for their powerful cutting force and compact design for handling small to medium-sized metal materials. It typically features a single rotating scissor that is capable of shearing materials such as rebar, pipe, and sheet metal.
Tiger Head Shearing Machine: It is designed to be more suitable for handling large and heavy metal materials such as steel beams and scrap machinery. It gets its name from the shape of its scissors, which resemble a tiger’s head. Tiger shears usually have double scissors to provide greater shearing power and stability.
Gantry Cutting Machine: It is a heavy-duty metal shearing machine designed to handle extremely large sizes and thicknesses of metal materials, such as scrap ships and large metal components. It utilizes a large robotic arm and multiple scissor blades for powerful shearing capabilities.
working principle of metal cutting machines
All three types of shears work by applying a shearing force to place the metal material between the shear blades and then applying pressure to cut the metal material. Alligator shears and tiger shears typically utilize a hydraulic system to provide the shearing force, while gantry shears are usually driven by a large electric motor and mechanical drive system.
The design and configuration of the shear blades vary depending on the model of the shear to meet the needs of handling different sizes and types of metals. These machines play an important role in the metal recycling industry by helping to convert scrap metal into valuable raw materials.
alligator metal shearing machine
General shear in 800mm, 1000mm, and 1200mm, suitable for small, medium-sized scrap steel processing and recycling points, need to be manually discharged. The advantage is cheap, the general shear can meet individual households, small scrap metal recycling station for scrap steel processing treatment.
machine using scope
Hydraulic metal shear machines are powerful metal shears that are widely used in the metal recycling and processing industry. The scope of its use includes but is not limited to the following:
- Scrap Car Dismantling: it can be used to dismantle scrap cars by cutting and separating the metal parts of the car, such as the body, engine, and chassis.
- Construction and Demolition Waste Disposal: it can handle metal wastes generated from construction sites and demolition projects, such as reinforcing bars, beams, and steel pipes.
- Metal Processing Plant: for cutting and processing metal materials for different engineering and fabrication needs.
- Pipes and Pipes Fabrication: for cutting and machining various types of metal pipes to ensure accurate dimensions and quality.
shear main structure
Its main structure includes the following key components: Frame, Hydraulic Cylinder, Blade Assembly, Hydraulic System, Electrical Control System, and Shear Compartment. Shear Compartment, Guards and Safety Devices, Lubrication System.

tiger head metal cutter machine
It has a large pressure (generally 350 tons up), small size, a wide range of processing, low noise, large shear section, easy to adjust the mouth of the scissors, and so on.
Machine application range
- Scrap Iron and Aluminum Recycling: commonly used in the recycling process of scrap iron and aluminum for cutting and processing small metal parts, chips, and scrap.
- Metalcraft Product Manufacturing: for cutting and processing light metal materials, such as furniture, decorative items, metal parts, etc.
- Repair and Maintenance: Also commonly used in the maintenance of mechanical equipment for cutting and trimming metal parts to maintain the performance and functionality of the equipment.
- Scrap Appliance Dismantling: Used to dismantle and dispose of metal parts, such as steel plates, aluminum housings, etc., in scrap appliances and electronic equipment.
metal cutter structure
Similar to the structural components of an alligator shear, these main structural components work together to enable it to cut metal materials efficiently and adapt to a wide range of cutting needs.

| Force | 260T | 315T | 400T |
| Power | 22kw | 30kw | 37kw |
| Length of blade | 1200mm | 1200mm | 1200mm |
large gantry metal shear
Huge size, suitable for large-scale scrap steel recycling station, high efficiency, shear scrap steel volume, daily output of 30-90 tons ranging (different models of output and efficiency are different). The price is a little higher, the shear effect is good, saves labor, fully automatic operation.
Scope of Application
- Scrap Metal Recycling: it is widely used to process large-scale metal scraps, such as scrap cars, scrap ships, and scrap steel components.
- Ship Dismantling: it can cut and dismantle metal parts of scrap ships, such as hulls, plates, and cabin structures.
- Bridge and Tunnel Construction: in bridge and tunnel construction, it can be used to process and cut bridge components, steel piles, tunnel walls, etc.
- Metallurgical Industry: In the metallurgical industry, it can be used to cut and process metal blocks and materials generated in the steelmaking and casting process.
- Engineering Machinery Manufacturing: Used for metal processing in the manufacture of large engineering machinery and equipment, such as excavators, loaders, bulldozers, etc.
All three types of metal shears have the same main components and are capable of cutting metal materials efficiently and adapting to a variety of cutting needs. Regular maintenance and servicing are key to ensuring their performance and safety.
