In industries like scrap steel recycling, automobile dismantling, and steel structure demolition, there’s a device that allows excavators to cut through thick steel bars, I-beams, and car frames as easily as cutting paper with scissors. This is the metal shear for excavators, also called an excavator hydraulic shear. Once mounted on an excavator, it eliminates the need for a bucket, directly shearing metal at ten times the speed of oxygen cutting, while also saving money. The YG excavator metal shear is mounted on the front of the excavator and used to cut scrap steel plates, steel bars, I-beams, scrapped car frames, and other metal materials. It is widely used in scrap dismantling and factory demolition projects.
The machine consists of five core components: a high-strength cutter body assembly, a high-torque hydraulic cylinder, a rotary hydraulic motor, a quick-connect pin, and wear-resistant cutter blocks. The cutter body is forged from high-hardness, wear-resistant alloy steel and undergoes quenching and tempering treatment for impact and wear resistance. The rotary motor supports 360-degree free rotation, facilitating multi-angle material clamping. YG can customize specifications according to the tonnage of the customer’s excavator. Mini excavators are equipped with mini excavator shears, while medium and large excavators are matched with heavy-duty shears. Please contact us now for more product information.

What Is the Working Principle of an Excavator Metal Shear?
Understanding the working principle of an excavator metal shear is actually quite simple, mainly consisting of three parts: power transmission, hydraulic cylinder drive, and jaw shearing.
First, the excavator’s hydraulic system provides high-pressure hydraulic oil, which is delivered to the hydraulic cylinder of the shear through hydraulic oil pipes.
Under the push of the high-pressure oil, the piston rod of the hydraulic cylinder extends, pushing the movable jaw towards the fixed jaw.
Both the movable and fixed jaws are equipped with high-hardness alloy blades. When the two blades close, the metal material in between is cut by a huge shearing force.
After shearing, the hydraulic cylinder reverses its oil supply, the piston rod retracts, and the movable jaw opens, ready for the next shear.
With the 360-degree rotation function, shearing can be performed from any angle, which is very convenient.
The entire process is continuous and efficient, with a shearing cycle taking only a few seconds.
In short: hydraulic power → cylinder drive → jaw shearing closure, completing the shearing process in three steps. Fast, powerful, safe, and efficient.

What Are the Suitable Applications of Excavator Metal Shears?
- Dismantling of end-of-life vehicles. This is the most common application of excavator metal shears. A single end-of-life vehicle can be dismantled in minutes using hydraulic shears, easily cutting through the engine, transmission, chassis, and body. Dismantling efficiency is 8-10 times that of manual labor.
- Scrap steel recycling and processing. In scrap steel recycling yards, various shapes of scrap steel, I-beams, channel steel, steel plates, and steel pipes can be cut into suitable sizes using hydraulic shears for easy loading, transportation, and remelting.
- Steel structure demolition. Demolition of old factories, old bridges, and old steel structures. Hydraulic shears can easily cut various steel structures, are safer than blasting, and faster than manual gas cutting.
- Dismantling of end-of-life ships. Dismantling end-of-life ships is a large-scale project, with hulls made of thick steel plates. Hydraulic shears can easily cut through the hull plates, significantly improving dismantling efficiency.
- Dismantling of scrapped construction machinery. Excavators, loaders, cranes, and other construction machinery are often scrapped; their bodies are made of thick steel plates and castings. Hydraulic shears can easily dismantle them, allowing for the recycling of steel and usable parts.
- Dismantling of abandoned oil tanks and pipelines. For abandoned oil tanks, oil pipelines, chemical pipelines, and other hazardous locations where open flames are prohibited, cold cutting with hydraulic shears is the safest method, producing no sparks and preventing explosions.
- Accident rescue. In traffic accidents where vehicles are deformed and people are trapped, hydraulic shears can quickly cut through the deformed vehicle body to rescue the trapped individuals. Many fire and rescue teams are equipped with mini excavator shears for rescue operations.
- Building demolition coordination. In building demolition projects, hydraulic shears are used in conjunction with hydraulic breakers: the breaker removes concrete, while the hydraulic shears cut rebar, working together efficiently.

Frequently Asked Questions about Excavator Attachment Hydraulic Shears
A1: For dismantling irregularly shaped thick steel and large vehicles, choose an excavator eagle shear; for shearing regular thin steel plates and rebar, choose a regular excavator hydraulic shear.
A2: Yes, the mini excavator shear has optimized hydraulic parameters and can be directly mounted on 3-6 ton excavators without modifying the excavator’s hydraulic system.
A3: No, the hydraulic shear’s force-bearing structure is not adapted for metal shearing and cannot compress and split rock. Use rock splitting attachments for rock breaking.
A4: No, the equipment uses modular blades; only worn blades need to be replaced, effectively reducing spare parts procurement costs.
A5: Installation is completed simply by connecting the excavator’s pins and hydraulic lines. A skilled worker can complete the entire machine’s mounting and commissioning within one hour.
A6: The entire machine’s hydraulic system undergoes multi-layer sealing and rust prevention treatment, allowing for continuous and stable operation in rainy, snowy, and open-air conditions.
A7: YG provides a 12-month warranty, excluding consumable parts such as blades. Blades are consumables and not covered under warranty, but YG offers discounted replacement prices.
