An excavator demolition shear is a heavy-duty hydraulic attachment designed to mount on excavators, delivering powerful cutting force for demolition work, scrap metal processing, and rebar cutting. It is an essential tool for construction, recycling, and industrial dismantling projects, enabling efficient cutting of steel structures, scrap metal, concrete reinforcement, and other hard ferrous materials.
YG series excavator hydraulic shear is engineered for reliable, high-efficiency performance across a wide range of harsh working conditions. With 5 optimized models from YG-620 to YG-4052, our lineup is tailored to fit excavators of different weights, from 5-ton mini excavators to 50-ton heavy-duty machines, delivering consistent, industry-leading cutting power for every application.

Excavator Metal Shear Working Principle:
The excavator demolition shear operates through a high-pressure hydraulic system powered by the host excavator. The hydraulic system drives the movable jaw of the shear to open and close with extreme force, leveraging a reinforced pivot design to amplify cutting pressure across the jaw’s tip, middle, and bottom positions. The integrated rotation function allows operators to position the shear at any angle for precise cutting, while the hardened steel blades deliver clean, efficient cuts through metal and rebar with minimal wear.
Excavator Demolition Shear Application
We design this series of hydraulic shear attachments primarily for two core application areas: building demolition and scrap metal recycling. In demolition projects, you can use them to cut through steel beams, rebar, metal frames and structural steel components during the dismantling of buildings, bridges and industrial facilities. In scrap recycling yards, it serves as a high-efficiency excavator metal shear, processing waste scrap, rebar, and discarded metal structures into manageable pieces for recycling and transport. It is also widely used in industrial dismantling, disaster relief demolition, and steel structure modification projects. This versatile excavator demolition shear adapts seamlessly to both indoor and outdoor working environments, from tight urban demolition sites to large-scale scrap recycling facilities.
Features of Excavator Demolition Shear:
- Graded Three-Stage Shear Force Layout： Exclusive to our YG series, each excavator hydraulic shear features a three-stage shear force design at the tip, medium and bottom positions, with graded cutting force ranging from 32.2T to 387.2T. It delivers peak power for thick heavy steel at the jaw bottom and precise cutting for thin scrap at the tip, eliminating invalid power loss.
- Tonnage-Matched 360° Rotation System： Our lineup adopts a differentiated rotation scheme. The compact YG-620 uses 360° collision rotation for flexible mini excavator operations, while YG-1413 and larger models are equipped with 360°full hydraulic rotation for precise positioning without repositioning the host machine.
- Full Tonnage Universal Fit With Direct-Mount Interface： YG 5 models precisely cover 5-50 ton excavators on the market, with working pressure and mounting dimensions fully matched to mainstream excavator specifications. The universal quick-change interface enables plug-and-play installation, with no need to modify the excavator’s hydraulic circuit or structure, avoiding damage to the host equipment.
- Optional Porcelain-Plating Anti-Corrosion Upgrade For Underwater Operations： For special working demands, we provide an optional customized porcelain-plating treatment for core components of our excavator metal shear, paired with an optimized sealed hydraulic system. This optional upgrade enables stable operation in underwater dismantling, river metal salvage and other wet conditions, greatly improving corrosion and abrasion resistance in harsh environments.
- High-Hardness Wear-Resistant Jaw With Reversible Blades： The jaw and cutting blades of our excavator demolition shear are crafted from premium hardened alloy steel. The reversible blade design is an optional feature that effectively doubles the service life of the attachment. It maintains stable cutting performance even under long-term continuous heavy-load operations, reducing the frequency of wear part replacements and overall operational costs.
How To Maintain Your Excavator Hydraulic Shear?
- Daily Pre-Operation Inspection: Before each use, inspect the shear for any signs of structural cracks, loose bolts, or worn pins and bushings. Check the hydraulic hoses for leaks, damage, or loose connections, and confirm that the jaw opens and closes smoothly without abnormal noise.
- Regular Blade Maintenance: The cutting blades are the core wear component of the shear. Inspect blade sharpness and wear regularly, and rotate or replace the blades when they become dull or excessively worn to maintain optimal cutting efficiency.
- Hydraulic System Care: Monitor the hydraulic oil level and quality of the host excavator, and replace the hydraulic oil and filter according to the equipment’s maintenance schedule. Ensure the hydraulic system is free of air and contaminants to prevent damage to the shear’s hydraulic cylinders.
- Regular Lubrication: Apply high-quality heavy-duty grease to all pivot points, rotation bearings, and moving parts on a fixed schedule, especially after continuous use or exposure to dusty, harsh working environments, to reduce friction and prevent premature wear.
- Post-Operation Care: After each use, clean the shear thoroughly to remove scrap metal, dust, and debris from the jaw and moving parts. Store the attachment in a dry, covered area when not in use for an extended period to prevent rust and corrosion.
