Metal shear for an excavator, also known as a hydraulic cutting shear, is a heavy-duty excavator attachment designed for cutting steel frames, waste metal, and reinforced construction materials. Driven by high-performance hydraulic circuits, it delivers steady and powerful cutting force to process steel beams, metal pipes, steel plates, and various metal components in demolition and metal recycling projects.
Manufactured with ultra-solid frames and reliable internal parts, this attachment can be mounted on most mainstream excavator models without complicated refitting. It greatly boosts on-site working efficiency and cuts labor and time costs, perfectly matching construction demolition, scrap metal processing, and industrial dismantling scenarios. Hydraulic demolition shears replace inefficient gas cutting and noisy hydraulic hammer breaking, bringing cleaner and safer cutting effects for scrap recycling yards. If you are looking for multi-functional cutting attachments for scrap dismantling workshops, our metal shear offers complete model-matching schemes for small dismantling plants and large demolition contractors.

Core Structural Composition Of Durable Hydraulic Metal Shear For Sale
Four core assemblies constitute the complete hydraulic shear structure, and every part is manufactured to withstand extreme cutting torsion and impact force:
- Main body and housing: Made of high-strength, wear-resistant steel to bear huge torsion and pulling force during continuous cutting work.
- Hydraulic cylinder: The core power component of the whole equipment, with a reinforced structure to resist frequent drastic pressure fluctuations.
- 360-degree rotary unit: All modern metal shears for an excavator are equipped with full continuous rotation structures. Operators can adjust the jaw cutting angle freely without moving the excavator chassis, reducing track wear and improving overall working efficiency.
- Cutting jaws and blades: The jaw structure determines the applicable processing materials, and replaceable blades are standard wearing parts for long-term construction.
6 Core Competitive Advantages Of High-Efficiency Metal Shear For Excavator
- Outstanding shear performance: It delivers a maximum working pressure of 800MPa, easily cutting Φ30 mm rebar and 10 mm thick steel plates to meet all common industrial metal cutting demands.
- Ultra-fast operation speed: It completes a full shear cycle within 2–3 seconds. Working speed is 50% faster than traditional cutting tools and effectively shortens construction schedules.
- Long service life design: Core components use imported seals and wear-resistant alloy materials. The unit supports over 8,000 working hours and lowers long-term maintenance expenses.
- Built-in safety protection system: It features overload protection and anti-drop devices. The system automatically avoids potential operational risks and fully safeguards operator safety.
- Strong universal compatibility: It fits most mainstream excavator brands. Operators can mount it rapidly via excavator quick couplers to boost equipment utilization.
- Energy-saving hydraulic design: Its hydraulic system uses variable pump control. It automatically lowers power frequency under no-load conditions and saves over 15% energy versus comparable hydraulic shears.
Frequently Asked Questions About Hydraulic Shear Cutting Machine
We provide models from 3 tons to 40 tons. Mini excavators of 3–9 tons are suitable for Model 40 and Model 80, while 12–40 tons heavy excavators can choose Model 180, 290, and 390 according to cutting demands.
The wear-resistant alloy blades can work for 200–400 hours under normal scrap cutting conditions. Replace the blades in time if obvious deformation or cracks appear.
Daily cleaning of blade residues, regular inspection of hydraulic oil leakage, and fastening of connecting bolts can effectively extend the service life of the whole set of equipment.
Key Selection Guidelines For Cost-Effective Hydraulic Demolition Shears
Four key factors can help buyers select the most suitable hydraulic shear attachment to avoid performance mismatch or premature equipment damage:
- Excavator hydraulic matching: Prior to purchase, you need to check whether the excavator metal shear fits your excavator’s hydraulic pressure, flow rate, and mounting interface standards.
- Processing material demand: Clarify the main materials to be cut, and select the jaw type with the corresponding shear capacity.
- Project operation scale: Choose heavy-duty models with strong shear force for large-scale continuous dismantling projects; lightweight small models are enough for short-term small cutting tasks.
- Comprehensive budget balance: Balance the initial purchase cost and long-term use value, and comprehensively evaluate the product’s durability, working efficiency, and daily operation saving effect.
