Hydraulic demolition shear is a powerful attachment designed to turn bulky scrap metal, concrete structures, and steel beams into manageable pieces with incredible speed and precision. Mounted directly onto an excavator, this tool transforms your machine into a high-performance recycling and demolition asset. For example, our YG-180 model suits 12‑18 ton excavators, weighing 1,600 kg and delivering a shearing force of 108 tons, while the YG-290 and YG-390 handle larger carriers with forces up to 250 tons. Whether you are breaking down car bodies, cutting rebar, or dismantling industrial frames, the hydraulic demolition shear offers unmatched cutting efficiency. Its robust construction ensures long service life even in the toughest job sites, and its simple hydraulic connection makes installation quick and hassle‑free.

Hydraulic Demolition Shear Attachment Combines Power, Precision, and Durability
Every hydraulic demolition shear we manufacture goes through strict quality control to guarantee consistent performance under extreme conditions.
- The YG series features a reinforced jaw design with wear‑resistant steel plates, ensuring the cutting edges stay sharp after thousands of cycles.
- With driving pressure up to 320 MPa and oil flow rates from 250 to 350 L/min, these shears deliver rapid opening and closing actions – the YG‑180 opens 600 mm, the YG‑290 opens 740 mm, and the YG‑390 opens 800 mm, allowing you to grip large objects firmly.
- Shearing depth ranges from 460 mm to 650 mm, so you can process thick materials in a single bite. The overall length varies from 1,900 mm to 2,700 mm, giving you excellent reach without sacrificing maneuverability.
- Noise and vibration are minimized thanks to advanced damping technology, protecting both the operator and the carrier.


How Does a Hydraulic Demolition Shear Actually Work?
- When the excavator’s hydraulic system sends pressurized oil into the shear’s cylinders, it pushes the moving jaw toward the fixed jaw. This creates an immense clamping force that grips the material between the sharp, replaceable blades.
- As the jaws continue to close, the leverage principle multiplies the hydraulic pressure, turning it into a concentrated cutting action that slices through steel, concrete, or mixed debris like a giant pair of scissors.
- The operator controls the entire process from the cab using standard foot pedals or joysticks, making it intuitive even for less experienced drivers.
- A built‑in rotation device (optional on some models) allows the shear to tilt and turn, so you can approach the workpiece from the best angle without repositioning the excavator.
- After each cut, the jaws open automatically, releasing the fragments onto the ground or into a waiting container. This cycle repeats rapidly, enabling continuous workflow.


Where Can You Put This Powerful Tool to Work?
Scrapyards rely on it to flatten old cars, separate copper wiring from aluminum frames, and prepare ferrous scrap for shipping to steel mills.
Demolition contractors use it on building sites to chop reinforced concrete pillars, cut through elevator shafts, and dismantle bridge sections piece by piece.
Recycling centers employ it to process bulky waste like refrigerators, washing machines, and storage tanks, reducing their volume for easier sorting and shredding.
Even in disaster recovery operations, emergency crews have found this tool invaluable for clearing collapsed structures and creating safe access paths.

While the YG‑180, YG‑290, and YG‑390 are our best‑selling hydraulic demolition shears, we also offer heavier models for 40‑70 ton excavators and compact versions for 5‑10 ton machines. If your excavator is not in this range, we also support customization service. In addition, we produce complementary attachments such as hydraulic grapples, pulverizers, and crusher buckets that pair perfectly with your shear for multi‑purpose operations. If you are handling rebar, we recommend our metal shear. We understand that every job site has unique demands, so we welcome custom orders based on your needs.
