In today’s fast-growing recycling industry, every piece of equipment matters. Metal recycling businesses must balance efficiency, performance, and cost to stay competitive. Among all the tools used for cutting and processing scrap metal, the alligator shear machine stands out for its power and simplicity.
However, while new alligator shears can be expensive, there is a smart and cost-effective alternative — the used alligator shear machine. Many metal recyclers around the world are now realizing that buying a well-maintained second-hand machine can deliver the same performance at a fraction of the price.
This article explores why investing in a used alligator shear makes sense, what benefits it offers, how to use it properly, and how to choose the best model for your needs.
What Is An Alligator Shear Machine?
An alligator shear machine — sometimes called a crocodile shear — is a type of hydraulic cutting equipment widely used in the metal recycling industry. The name comes from its design: the upper blade opens and closes like the jaw of an alligator, delivering strong shearing force to cut through various metal materials.
These machines are capable of cutting:
-
Steel bars and rods
-
Scrap iron and light metal
-
Pipes, rebar, and angle steel
-
Non-ferrous metals like aluminum and copper
Alligator shears are known for their durability, compact structure, and ease of operation, making them essential in scrap yards, foundries, and steel processing plants.
Why Choose A Used Alligator Shear Machine?
1. Save Substantial Costs
The biggest advantage of buying a used alligator shear is the lower investment cost. A new shear can be quite expensive, but a used one—especially from a reliable supplier—can save you 40% to 70% of the original price. This makes it an ideal choice for startups or recycling plants looking to expand without overextending their budget.
2. Proven Performance And Stability
Unlike new machines that need break-in time, a well-maintained used shear has already proven its performance and reliability in actual production. With regular maintenance and proper testing, a used machine can work efficiently for many more years.
3. Shorter Delivery And Setup Time
New machines often require long lead times for production and delivery. Used equipment, on the other hand, is usually ready for immediate shipment. This means you can put the machine into operation quickly, ensuring minimal downtime and faster returns.
4. Eco-Friendly And Sustainable
Buying second-hand machinery contributes to environmental sustainability. Instead of manufacturing new equipment, which consumes energy and resources, you’re extending the life of an existing machine — reducing industrial waste and your carbon footprint.
5. High Return On Investment
With lower initial costs and high working efficiency, a used alligator shear provides an excellent return on investment (ROI). For most recycling companies, it can pay for itself within a short period through daily metal cutting operations.
Main Benefits Of Using An Alligator Shear Machine
No matter if it’s new or used, an alligator shear delivers impressive results. Here are the main advantages:
-
Strong Shearing Force: Efficiently cuts steel, iron, and copper materials.
-
Compact Design: Takes up less space, suitable for small workshops.
-
Simple Operation: Easy for workers to learn and operate.
-
Low Maintenance Needs: Durable hydraulic system ensures long-term reliability.
-
Versatile Applications: Widely used in scrap recycling, demolition, and metal recovery.
How To Use A Used Alligator Shear Machine
Operating a used alligator shear machine correctly is essential for safety, performance, and longevity. Below is a simplified guide:
Step 1: Check Before Operation
-
Ensure the hydraulic oil is at the correct level.
-
Inspect the cutting blades for sharpness and cracks.
-
Confirm the electrical system is functioning safely.
Step 2: Setup The Machine
-
Place the machine on a stable surface and secure it properly.
-
Connect to the proper power source (typically 380V).
-
Make sure safety covers and guards are installed.
Step 3: Start Cutting
-
Position the scrap metal between the blades.
-
Use the hydraulic control lever to close the jaw.
-
Wait for a complete cut before releasing pressure.
-
Repeat as necessary for continuous operation.
Step 4: Maintenance After Work
-
Clean away any metal debris.
-
Lubricate the joints and moving parts.
-
Replace hydraulic oil and blades periodically.
Safety Tip: Always wear gloves, goggles, and ear protection when operating or maintaining the shear.
How To Choose The Right Used Alligator Shear Machine
Before buying, it’s important to know what specifications match your needs. Here are key factors to consider:
1. Shearing Force (Ton Capacity)
This determines what type of materials the machine can handle.
-
63–125 tons: For light scrap, small metal rods, and aluminum.
-
160–250 tons: Suitable for medium-sized steel bars and pipes.
-
320–500 tons: For heavy-duty industrial cutting and thick scrap.
2. Blade Length
Blade size affects cutting efficiency and capacity. Common sizes are 400mm, 600mm, 800mm, and 1000mm. Longer blades allow cutting larger materials but require higher power.
3. Motor Power
A strong motor ensures fast cutting and smooth operation. Look for machines with 15–30 kW motors depending on your workload.
4. Machine Condition
Inspect the following carefully:
-
Hydraulic cylinders (check for oil leaks)
-
Blade sharpness and alignment
-
Frame condition (no cracks or rust)
-
Control panel and electrical components
5. Brand And Supplier
Choose a reputable manufacturer or supplier that provides after-sales support, spare parts, and maintenance services.
Trusted suppliers like Shanghai Aultral Machinery Co., Ltd offer used and refurbished hydraulic shears that meet CE and ISO9001 standards.
Tips For Maintaining A Used Alligator Shear Machine
Proper care can extend the machine’s service life significantly. Here’s what to do:
-
Change Hydraulic Oil Regularly: Replace every 3–6 months.
-
Keep Blades Sharp: Dull blades reduce efficiency and strain the motor.
-
Clean After Use: Remove debris and prevent rust buildup.
-
Check Bolts And Connections: Tighten loose parts to avoid vibration damage.
-
Store In A Dry Environment: Keep the machine away from moisture.
With these simple habits, even a used machine can maintain high cutting performance for many years.
Common Applications Of Used Alligator Shears
Used alligator shears are versatile and used in many industries, including:
-
Scrap metal recycling centers
-
Automobile dismantling plants
-
Steel mills and foundries
-
Construction and demolition sites
-
Machinery repair workshops
These machines efficiently cut metal scrap into smaller, uniform pieces, making transport and smelting more convenient.
Practical Buying Advice For First-Time Buyers
If it’s your first time buying a used alligator shear, here are a few extra tips:
-
Ask for videos or live demonstrations to confirm machine performance.
-
Request a maintenance log to understand previous repairs.
-
Choose a supplier that offers testing and inspection services.
-
Confirm that spare parts (like blades and seals) are available.
-
Ensure the machine complies with safety and electrical standards in your country.
