3150kN Hydraulic Alligator Shear For Heavy Scrap Metal Cutting With Air Cooling Or Water Cooling
Product Overview
The Q43-3150 Alligator Shear is a heavy-duty hydraulic scrap metal cutting machine with a nominal shearing force of 3,150 kN (315 tons). It is designed to cut long, oversized, and irregular ferrous metal into shorter, manageable pieces for easier storage, transportation, sorting, and furnace feeding.
Compared with manual flame cutting, this hydraulic alligator shear provides a cleaner and more consistent processing method. Its open feeding structure makes it convenient to load long materials such as round bars, steel plates, pipes, angle steel, channels, and industrial offcuts. The hydraulic hold-down device stabilizes the material before cutting, helping reduce movement and improve operating safety.
The Q43-3150 is suitable for scrap yards, steel mills, foundries, dismantling facilities, and metal-processing factories that require reliable cutting performance without the larger footprint of a gantry shear.
Cause
Long and irregular scrap metal can create several problems for recycling businesses:
- Oversized material occupies excessive storage space
- Long scrap is difficult to stack and transport safely
- Manual flame cutting increases labor and fuel costs
- Irregular feed sizes reduce furnace-loading efficiency
- Thick scrap cannot be processed by small alligator shears
- Unstable material may move during cutting
When heavy scrap is delivered in mixed shapes and sizes, an ordinary light-duty shear may not provide enough cutting force. Buyers therefore need a stronger machine that can process thicker materials while remaining simple to operate and maintain.
Solution
The Q43-3150 hydraulic alligator shear uses a high-pressure hydraulic system to generate powerful and stable cutting force. Scrap is placed between the blades, secured by the hold-down system, and cut into shorter sections by the moving upper blade.
Its main advantages include:
- 315-ton cutting force for medium and heavy ferrous scrap
- Open feeding design for convenient loading of long materials
- Hydraulic hold-down system to stabilize scrap before shearing
- Replaceable cutting blades for easier long-term maintenance
- Adjustable cutting operation for different material dimensions
- Compact structure requiring less space than a gantry shear
- Automatic and manual control options for flexible operation
- Customizable power supply according to the destination country

The specifications are for reference. Actual cutting capacity depends on the material grade, shape, hardness, feeding position, and cutting conditions. Final parameters should be confirmed before production.
Application
The Q43-3150 scrap metal alligator shear is widely used in:
- Scrap metal recycling yards
- Steel mills and foundries
- Vehicle dismantling facilities
- Machinery manufacturing factories
- Building demolition projects
- Metal fabrication workshops
- Industrial waste-processing centers
It can process round steel, square bars, steel plates, pipes, rebar, angle steel, channels, light beams, and machinery offcuts. High-strength alloy steel, hardened shafts, railway rails, and unusually thick materials should be evaluated separately before cutting.
How It Works
The operator places the scrap on the feeding table and moves it into the cutting position. The hydraulic hold-down device presses the material firmly to reduce movement. The upper blade then moves downward under hydraulic pressure and cuts the scrap against the fixed lower blade.
After the blade returns, the material is advanced to the next cutting position. The cycle can be controlled manually or operated continuously according to the machine configuration. The finished scrap can be transferred directly to a storage area, conveyor, container, or furnace-feeding system.
How To Choose
Buyers should select an alligator shear according to the maximum material size rather than only the average scrap dimensions. Important factors include:
- Material type and steel grade
- Maximum diameter or thickness
- Required cutting length
- Daily processing capacity
- Feeding method
- Available installation area
- Local voltage and frequency
- Required operating hours per day
If most materials are light and small, a lower-force model may provide better investment efficiency. If the scrap includes thick plates, large beams, or dense structural steel, a larger alligator shear or gantry shear may be more suitable.
FAQ
What materials can the Q43-3150 Alligator Shear cut?
It is mainly designed for ordinary carbon-steel scrap, including round bars, square bars, plates, pipes, rebar, channels, and industrial offcuts. Material photos and dimensions should be checked before confirming suitability.
Can it cut alloy steel or hardened metal?
The machine may cut some alloy materials, but actual capacity will be lower than for ordinary carbon steel. Hardened shafts, rails, and high-strength alloy steel require separate technical evaluation.
How often do the blades need to be replaced?
Blade life depends on material hardness, cutting position, working hours, and maintenance. The blades are replaceable and can normally be rotated or reground when the cutting edge becomes worn.
Is manual feeding required?
Long materials can be loaded manually when site safety conditions permit. For heavy or irregular scrap, a grab machine or other mechanical loading equipment is recommended.
Can the voltage and control system be customized?
Yes. The motor voltage, frequency, control method, cooling system, safety protection, and other configurations can be customized according to the buyer’s local conditions.
