Excavator shear for sale is an attachment for an excavator, usually used to cut and crush hard materials such as concrete, bricks, rocks, metals, etc. Driven by the hydraulic system, the hydraulic shear has a strong cutting force and accurate control ability, which can quickly and efficiently complete various tasks. The blade of the hydraulic shear is made of high-hardness alloy materials and has strong wear resistance and durability after special treatment. Hydraulic shears can be widely used in building demolition, municipal engineering, mining, bridge maintenance, and other fields, and are particularly effective for work that requires fast and precise cutting. There are single-cylinder excavator shears and double-cylinder hydraulic shears available. Double-cylinder hydraulic shears have greater compression force and are suitable for metal materials with higher hardness. While single-cylinder excavator shears have a simpler structure and are suitable for cutting small and light metal materials.
Doule-cylinder type excavator shear attachment is suitable for cutting and crushing steel frame structures and automobile beams, and dismantling of scrap cars and scrap metal products. The whole machine is made of high-strength wear-resistant plate with high strength and light weight. The high-pressure large-diameter oil cylinder is equipped with a piston cylinder sleeve to provide great power while preventing damage to the piston rod. Its two scissor plates are equipped with a synchronization device to achieve synchronous opening and closing. The blade is made of high-toughness and high-strength steel to cut iron like mud. The blade is interchangeable and reusable on all four sides to greatly reduce loss. The double-sided guide friction block can be adjusted at any time to ensure perfect cutting. The reasonable lubrication oil channel effectively reduces daily wear and reduces friction, making the shearing smooth and powerful.
Single-cylinder type excavator shear for sale is suitable for dismantling vehicles such as motorcycles, vans, and agricultural machinery, separation of tire hubs, compression and reduction of scrap steel, demolition of other buildings, shearing steel, and other crushing and shearing operations. It is made of high-quality steel, lightweight and wear-resistant. Its pin is made of alloy steel with a built-in oil channel, high strength, and good toughness. It uses a rotary motor, full-angle rotation, high torque, and fast speed. The oil cylinder uses a honing tube, a short working cycle, and a long life. The knife block is made of wear-resistant alloy steel, with high-temperature resistance, and deformation resistance. The single oil cylinder design increases the opening and closing speed under the condition of unchanged bite force, saving time and improving efficiency. The two front knife plates are equipped with a synchronization device to achieve synchronous opening and closing. The blade is made of high-toughness and high-strength steel, which can easily cut the steel bars in cement.

Features and Benefits of Metal Shear for Excavator
High efficiency and energy saving: Hydraulic shear can utilize the high pressure and high speed provided by the hydraulic system during the working process, making the work efficiency high and saving time and labor costs.
Precision control: The hydraulic system has precise control capabilities and can adjust the working pressure and speed according to actual needs to accurately complete the work tasks.
Reliable: Excavator shear for sale is controlled by the hydraulic system, which is stable and reliable during the working process and easy to operate.
Stable and durable: Metak shear for excavator is made of high-quality alloy steel, with high strength and wear resistance, and long service life.
The versatility of the excavator shear makes it an indispensable tool across several demanding industries.
Building Demolition and Structural Dismantling: This is perhaps the most common application. Shears are used to systematically cut through the steel framework, I-beams, and reinforced concrete of bridges, factories, and commercial buildings. This reduces large structures into segments suitable for safe removal.
Scrap Metal Recycling: In scrap yards, the shear is a workhorse, processing incoming oversized scrap metal—such as engine blocks, railway components, and heavy pipes—into smaller pieces that meet specific mill-ready specifications for smelting and reuse.
Automotive Recycling and Vehicle Dismantling: Specialized shears are used to cleanly and quickly cut through vehicle chassis and frames, separating high-value metals from non-metallic components.
Railway and Pipeline Infrastructure: They are highly effective for cutting old rail lines, thick steel pipes, and utility infrastructure during maintenance or removal projects.

Working Principle of the Excavator Shear for Sale
The operation of an excavator shear is a perfect illustration of applied hydraulic and mechanical engineering principles.
Hydraulic Power Input: The operator engages the auxiliary hydraulic circuit of the excavator. This sends high-pressure oil from the excavator’s pump through the hydraulic lines to the shear’s main cylinder.
Conversion to Mechanical Force: The high-pressure fluid acts on the large piston inside the shear cylinder. This action converts the hydraulic energy into a massive linear force.
Leverage and Shearing Action: The cylinder’s rod is connected to the moving jaw via a kinematic linkage system. This system is engineered to maximize the mechanical advantage, multiplying the cylinder’s linear force into a concentrated shearing force at the blade apex.
The Cut: As the moving jaw closes against the fixed lower jaw, the opposing cutting blades, operating with precision alignment, shear the material like scissors. The initial contact is made by the piercing tip, followed
