Excavator metal shear is a heavy-duty hydraulic attachment engineered to slice through scrap metal, structural steel beams, iron pipes, and rebar with industrial precision. Mounted on standard carrier excavators ranging from 4 to 50 tons, this powerful attachment transforms standard excavators into mobile demolition powerhouses, allowing operators to process heavy metal structures directly on-site. Designed with high-strength alloy jaws, indexable cutting blades, and high-pressure hydraulic cylinders, a professional metal shear attachment for excavator systems replaces manual torching or oxy-fuel cutting. This significantly improves job site safety, lowers labor expenses, and speeds up throughput in scrap recycling yards, dismantling facilities, and urban demolition zones.

How Does the Excavator Scrap Metal Shear Work?
The operational mechanism relies on the carrier excavator’s hydraulic power system. Hydraulic oil flows under high pressure—operating at working pressures from 35 MPa up to 320 MPa depending on cylinder configuration—into the attachment’s double-acting cylinder.
Hydraulic Force Conversion: High-volume oil flow (reaching up to 350 L/min on larger models like the YG-390) drives the main jaw closed with immense crushing pressure.
Dual-Jaw Shearing Mechanism: The fixed lower jaw stabilizes the target material, while the moving upper jaw engages heavy-duty shear blades against structural steel.
Rotational Positioning: Optional 360-degree hydraulic rotation modules allow precise jaw positioning without moving the parent excavator, maximizing speed during complex overhead demolition work.
Compatible Materials: What Can It Cut?
An excavator metal shear effortlessly processes ferrous and non-ferrous scrap across demolition and industrial recycling operations:
Structural Steel: H-beams, I-beams, channel steel, angle iron, and steel plates.
Pipelines & Tubing: Large-diameter steel pipes, gas mains, and industrial boiler tubing.
Vehicles & Machinery: Automotive bodies, truck frames, heavy equipment chassis, and railway train carriages.
Reinforced Metal Scrap: Concrete rebar grids, wire mesh, and cable bundles.
Maritime & Aerospace Metal: Ship hulls, barge frames, and structural aircraft aluminum scrap.
10 Features of Hydraulic Metal Shear Attachment for Excavator
Massive Shearing Force: Delivers front-end crushing forces up to 172 Tons and central crushing force ratings up to 464 KN (YG410R model) for dense structural steel.
High-Pressure Hydraulic Cylinders: Built for 35 MPa to 320 MPa driving pressure, yielding ultimate penetration force.
Versatile Boom & Arm Mounting: Options for forearm mounting (e.g., YG180R on 18–27T excavators) or main boom/large arm installation (14–18T excavators) maximize reach and stability.
Wide Jaw Openings: Jaw throat openings up to 800 mm (YG-390 model) enable effortless feeding of bulky profile steel.
Deep Throat Depth: Generous throat depth reaching up to 720 mm (YG410R) allows deep material insertion for clean, single-pass cuts.
Optimized Hydraulic Oil Flow Requirements: Designed for efficient hydraulic flow rates between 250 L/min and 350 L/min, ensuring rapid jaw cycling times.
Heavy-Duty Wear-Resistant Alloy Construction: The excavator metal shear is built with high-tensile steel plates to resist jaw deflection and frame deformation under extreme torsional loads.
Indexable Four-Way Cutting Blades: Reversible and replaceable blade inserts offer four fresh cutting edges per set, drastically cutting maintenance costs.
Compact & Balanced Overall Length: Lengths ranging from 1,900 mm to 3,900 mm maintain proper center-of-gravity balance on carrier machines.
Flexible Operating Weight Range: Attachments span from light 650 kg units to heavy-duty 4,700 kg tools, matching diverse fleet profiles.
Application Scenarios of the Hydraulic Shear Attachment
Scrap Metal Recycling Yards: Slicing raw scrap into localized size classes for efficient furnace batch loading.
Structural Building Demolition: The excavator metal shear is applied in cutting steel skeletons, reinforced girders, and internal metal support structures safely.
Shipyard & Train Dismantling: Stripping down decommissioned steel vessels, barges, railcars, and heavy industrial plant machinery.
Disaster Relief & Site Clearance: Clearing twisted steel debris quickly from disaster sites or municipal clearance projects.
Choosing the Right Model Metal Shear Attachment for Excavator
Selecting the appropriate excavator metal shear depends on your excavator’s size and the type of work you’ll be performing. Here’s a quick guide:
