The excavator shear attaches to the front of the machine and runs on the excavator’s hydraulic system. The operator controls it from the cab. Changyu designed the DSX series for efficient shearing of steel structures, frames and automobile beams. The shear head rotates to the required cutting angle, so each cut lands exactly where the operator needs it.
The shear suits four main jobs:
• Dismantling scrap cars
• Demolishing factory steel structures
• Breaking up ships
• Shearing scrap steel such as steel bars, steel sections, tanks and pipes
Because the attachment cuts with hydraulic force, crews can process steel on site and load it straight into trucks or bins. This saves handling time and reduces the need for flame cutting on many jobs.
It is different from a hydraulic breaker. A breaker hits and breaks hard material such as rock and concrete. A shear cuts metal. Contractors who handle both materials often use both attachments on the same excavator.
• DSX180: Applicable Type 120-180, max opening 680 mm, cutting depth 500 mm, weight 1,600 kg.
• DSX280: Applicable Type 200-300, max opening 740 mm, cutting depth 550 mm, weight 3,100 kg.
• DSX380: Applicable Type 330-400, max opening 800 mm, cutting depth 650 mm, weight 4,300 kg.
• DSX480: Applicable Type 400+, max opening 920 mm, cutting depth 750 mm, weight 6,200 kg.
Smaller models fit lighter work such as car bodies, light sections and pipes. Larger models handle thicker steel and bigger structures. The full table is in the technical parameters section below.
This design gives three practical benefits:
• Flexible operation, because the operator adjusts the cutting angle on the spot
• Stable performance during repeated cutting cycles
• High torque for turning the shear while it holds heavy material
Angle control matters most on twisted steel, car frames and tank walls. A rotating hydraulic shear reaches these cuts with fewer machine moves, which shortens cycle time.
The structure is also optimized to resist deformation. A body that keeps its shape under load holds the blade gap steady, and a steady blade gap supports clean cuts over a longer service life.
• Ask for photos or a video of the shear body before shipment
• Ask how the supplier checks weld quality and dimensions
Blade wear depends on what you cut. Thick steel sections, rebar bundles and hardened parts wear blades faster than thin car sheet metal. Plan for this before you buy.
• Delivery time for spare blades
• Blade replacement instructions for your maintenance team
Stocking one spare blade set can reduce downtime for distributors and contractors who run the hydraulic shear every day.
A lighter shear with strong cutting force lets a given excavator work with more confidence. It also leaves more of the machine’s lifting capacity for the steel you handle. Always compare the shear weight with your excavator’s rated capacity before ordering.
Car recyclers often cut vehicles into transport-ready pieces. This improves loading density and speeds up delivery to the steel mill. For heavy vehicles, you can also compare our Eagle Beak Scissors, an excavator front-end tool for shearing scrap steel and dismantling scrapped cars.
Many demolition projects also include reinforced concrete. In that case, our Hydraulic Crushing Pliers can crush concrete and cut exposed rebar, while the shear handles the structural steel. Using both tools lets one carrier cover most of the demolition sequence.
Ship recycling yards, scrap processors and industrial clean-up teams all deal with mixed steel. The DSX excavator shear cuts steel bars, steel sections, tanks and pipes into manageable pieces.
• Ship breaking: cut plates, frames and pipe runs into pieces
• Steel bars: shear long bars to sizes that are easy to transport
• Tanks: cut tank shells into sections for removal
• Pipes: shear pipework and tubes on site
Always follow local safety rules before cutting tanks. Clean and check them first. After cutting, many yards load the pieces with a grapple. See our Hydraulic Peel Grapple for material handling.
Notes for buyers:
• Max opening is the widest jaw gap. It limits the size of material you can take in.
• Cutting depth shows how far the jaws reach into the material.
• Weight affects carrier matching and shipping cost.
• Applicable Type follows the format on the Changyu product page. Confirm exact excavator compatibility with our team before ordering.
• Ask our team for the hydraulic flow and pressure requirements of your model.
• Clear model data: opening, cutting depth and weight
• Spare blade availability
• A test or working video of the exact model
• Packing method and shipping documents
• Technical support after delivery
A supplier who answers these questions in detail is usually easier to work with after the sale.
If you cut heavy or mixed steel every day, a double cylinder design is a practical choice. If your work is light and occasional, a simpler shear may be enough. Our team can advise you based on your application.
Buyers work with different carriers, materials and site conditions. If your project needs a specific configuration, send your requirements and the team will review what is possible. Distributors, contractors and procurement teams are welcome to ask about quantities, packing and delivery terms.
• Excavator brand, model and tonnage
• Material you cut and the thickest piece
• Required model: DSX180, DSX280, DSX380 or DSX480
• Quantity and destination port
• Any special requirement for packing or documents
Most questions are easier to settle when this information is in your first message.

Hydraulic Double Cylinder Shear DSX180-DSX480 | Manufacturer
Cutting heavy steel on site is slow, risky and expensive when crews rely on torches and manual dismantling. A Hydraulic Double Cylinder Shear mounted on an excavator changes that. It cuts beams, tanks, pipes, rebar and car frames with hydraulic force, right where the material sits.
Jiangyin Changyu Machinery Co., Ltd. manufactures the Hydraulic Double Cylinder Shear in four models: DSX180, DSX280, DSX380 and DSX480. This guide explains how the shear works, where it performs best and what to check before you place an order. It is written for importers, distributors, contractors and procurement teams who compare suppliers before sending an inquiry.
Hydraulic Double Cylinder Shear for Excavators: Overview
The excavator shear attaches to the front of the machine and runs on the excavator’s hydraulic system. The operator controls it from the cab. Changyu designed the DSX series for efficient shearing of steel structures, frames and automobile beams. The shear head rotates to the required cutting angle, so each cut lands exactly where the operator needs it.
The shear suits four main jobs:
• Dismantling scrap cars
• Demolishing factory steel structures
• Breaking up ships
• Shearing scrap steel such as steel bars, steel sections, tanks and pipes
Because the attachment cuts with hydraulic force, crews can process steel on site and load it straight into trucks or bins. This saves handling time and reduces the need for flame cutting on many jobs.
What Is a Hydraulic Double Cylinder Shear?
A hydraulic double cylinder shear is an excavator attachment that uses two hydraulic cylinders to open and close its jaws. Oil from the excavator drives the cylinders, and the jaws close on the steel and cut through it. Buyers also search for it as an excavator shear, scrap shear or demolition shear. These names usually describe the same type of attachment.It is different from a hydraulic breaker. A breaker hits and breaks hard material such as rock and concrete. A shear cuts metal. Contractors who handle both materials often use both attachments on the same excavator.
Hydraulic Double Cylinder Shear DSX180, DSX280, DSX380 and DSX480 Models
The DSX range covers small to large excavator classes. The number in the model name rises with size, and so do the opening, the cutting depth and the weight.• DSX180: Applicable Type 120-180, max opening 680 mm, cutting depth 500 mm, weight 1,600 kg.
• DSX280: Applicable Type 200-300, max opening 740 mm, cutting depth 550 mm, weight 3,100 kg.
• DSX380: Applicable Type 330-400, max opening 800 mm, cutting depth 650 mm, weight 4,300 kg.
• DSX480: Applicable Type 400+, max opening 920 mm, cutting depth 750 mm, weight 6,200 kg.
Smaller models fit lighter work such as car bodies, light sections and pipes. Larger models handle thicker steel and bigger structures. The full table is in the technical parameters section below.
360° Rotating Hydraulic Shear with Dedicated Slewing Support and Motor
Rotation is what makes a shear efficient on real job sites. Each DSX model has a dedicated slewing support and motor. This lets the operator turn the shear head to the right angle without repositioning the whole excavator.This design gives three practical benefits:
• Flexible operation, because the operator adjusts the cutting angle on the spot
• Stable performance during repeated cutting cycles
• High torque for turning the shear while it holds heavy material
Angle control matters most on twisted steel, car frames and tank walls. A rotating hydraulic shear reaches these cuts with fewer machine moves, which shortens cycle time.
Hardox 400 Shear Body for High Toughness and Wear Resistance
The shear body takes the heaviest load on every cut. Changyu builds it from imported Hardox 400 sheet material. This wear-resistant steel gives the body high toughness and strong resistance to high-intensity wear.The structure is also optimized to resist deformation. A body that keeps its shape under load holds the blade gap steady, and a steady blade gap supports clean cuts over a longer service life.
What buyers should confirm
• Ask for the body material to be written in your quotation or proforma invoice• Ask for photos or a video of the shear body before shipment
• Ask how the supplier checks weld quality and dimensions
Long-Life Imported Blades for Scrap Steel Cutting
Blades decide cut quality and running cost. The DSX series uses blades made of imported materials, selected for a long service life in scrap steel work.Blade wear depends on what you cut. Thick steel sections, rebar bundles and hardened parts wear blades faster than thin car sheet metal. Plan for this before you buy.
Spare parts to ask about
• Replacement blade sets for your model• Delivery time for spare blades
• Blade replacement instructions for your maintenance team
Stocking one spare blade set can reduce downtime for distributors and contractors who run the hydraulic shear every day.
Lightweight Design with High Shear Force
The DSX shear is lightweight yet delivers high shear force. Weight matters because the attachment hangs at the end of the excavator arm. Extra weight reduces stability and adds stress to the boom and stick.A lighter shear with strong cutting force lets a given excavator work with more confidence. It also leaves more of the machine’s lifting capacity for the steel you handle. Always compare the shear weight with your excavator’s rated capacity before ordering.
Hydraulic Shear for Scrap Car Dismantling
Scrap car dismantling is one of the main uses for the Hydraulic Double Cylinder Shear. The shear cuts frames, automobile beams, pillars and body panels. Operators can separate steel from other parts faster than with manual tools.Car recyclers often cut vehicles into transport-ready pieces. This improves loading density and speeds up delivery to the steel mill. For heavy vehicles, you can also compare our Eagle Beak Scissors, an excavator front-end tool for shearing scrap steel and dismantling scrapped cars.
Hydraulic Shear for Steel Structure and Factory Demolition
Factory demolition involves beams, columns, frames and roof trusses. The demolition shear cuts these members at height or on the ground, depending on the excavator setup. The result is smaller steel pieces that are easier to sort and haul away.Many demolition projects also include reinforced concrete. In that case, our Hydraulic Crushing Pliers can crush concrete and cut exposed rebar, while the shear handles the structural steel. Using both tools lets one carrier cover most of the demolition sequence.
Excavator Shear for Ship Breaking, Steel Bars, Tanks and Pipes
Ship recycling yards, scrap processors and industrial clean-up teams all deal with mixed steel. The DSX excavator shear cuts steel bars, steel sections, tanks and pipes into manageable pieces.
• Ship breaking: cut plates, frames and pipe runs into pieces
• Steel bars: shear long bars to sizes that are easy to transport
• Tanks: cut tank shells into sections for removal
• Pipes: shear pipework and tubes on site
Always follow local safety rules before cutting tanks. Clean and check them first. After cutting, many yards load the pieces with a grapple. See our Hydraulic Peel Grapple for material handling.
Technical Parameters: Max Opening, Cutting Depth and Weight
The table below shows the technical data for each DSX model.| Model | Applicable Type | Max Opening (mm) | Cutting Depth (mm) | Overall Dimension (mm) | Weight (kg) |

How to Choose the Right Double Cylinder Shear for Your Excavator
A wrong match wastes money and time. Use these steps to select the right double cylinder shear.1. Match the shear to your excavator
Start with your excavator brand, model and operating weight. Compare them with the Applicable Type column and the shear weight. Send your excavator model to the supplier so they can confirm the fit.2. Define the material you cut
List the steel you cut most often: thin car body, structural beams, thick plate, rebar or pipes. Choose a model with enough opening and cutting depth for your largest regular piece, not only the average one.3. Check hydraulic and mounting needs
Ask for oil flow and pressure requirements, hose connection details and the mounting interface. Check that your excavator’s auxiliary circuit can supply them. A mismatch can cause slow cutting or overheating.4. Compare supplier details
• Written specifications for body material and blade material• Clear model data: opening, cutting depth and weight
• Spare blade availability
• A test or working video of the exact model
• Packing method and shipping documents
• Technical support after delivery
A supplier who answers these questions in detail is usually easier to work with after the sale.
Double Cylinder Shear vs Single Cylinder Shear: What Is the Difference?
Both types cut steel, but they suit different jobs. The table gives a general comparison. Exact performance depends on the model and design.| Feature | Double cylinder shear | Single cylinder shear |
| Cylinders | Two cylinders drive the jaws | One cylinder drives the jaws |
| Typical use | Scrap cars, steel structures, ship breaking | Light scrap, pipes, general cutting |
| Force balance | Force comes from two points for steadier jaw closing | Force comes from one point |
| Structure | More components | Simpler structure |
| Purchase price | Usually higher | Usually lower |
If you cut heavy or mixed steel every day, a double cylinder design is a practical choice. If your work is light and occasional, a simpler shear may be enough. Our team can advise you based on your application.
