Specializing in robust, reliable, and technologically advanced demolition and recycling attachments, Guchuan is committed to empowering construction, demolition, and scrap processing industries with efficient solutions. Among our flagship products is the GCE-28 Hydraulic Eagle Shear, a state-of-the-art cutting attachment designed to redefine productivity for 20-28 ton excavators.

The GCE-28 is not just a tool; it is a precision-engineered system built for demanding applications. In an industry where time, safety, and material integrity are paramount, this hydraulic shear delivers unparalleled performance in cutting structural steel, beams, and heavy vehicle frames. This comprehensive guide delves into the engineering, applications, and superior advantages of the GCE-28, providing contractors and equipment managers with the insights needed to make an informed investment.

Technical Specifications & Design Overview

The GCE-28 is built with a focus on durability, power, and operational efficiency. Below are its detailed specifications, which form the foundation of its high performance:

Key Design Interpretations:

• Optimized Weight (2250 kg): Balances robust construction with excavator stability, preventing undue stress on the carrier while ensuring effective cutting momentum.

• Strategic Dimensions (Opening 460mm, Depth 530mm): Allows for handling and cutting of substantial structural profiles like H-beams and wide flange beams in a single bite.

• High Cutting Forces (up to 130 tons): Generates immense power to cleanly shear through high-tensile steel, reducing deformation and producing recyclable scrap.

• Adaptive Hydraulic Pressure (280-320 kg/cm²): Ensures compatibility with a range of 20-28 ton excavator hydraulic systems, optimizing performance without risking damage to the carrier.

Core Engineering & Technological Principles

The superiority of the GCE-28 stems from its advanced engineering principles and meticulous component selection.

1. Advanced Hydraulic Actuation & Control

At its heart, the GCE-28 operates on a high-efficiency hydraulic system. The dedicated rotary support and motor are custom-engineered for demolition shears. This system provides:

• High Torque & Smooth Rotation: Enables 360-degree continuous rotation for precise blade positioning without sacrificing power, allowing operators to tackle cuts from any angle.

• Stable Performance Under Load: Maintains consistent pressure and flow during the cutting cycle, preventing stalling or jerky movements that can damage material or the machine.

• Variable Cycle Control (7-155 seconds): Operators can adjust the opening and closing speed based on material thickness and type, enhancing efficiency and reducing unnecessary hydraulic strain.

2. Structural Integrity: The TDNM450 Plate Advantage

The shear's main body is constructed from TDNM450-grade steel plate. This material is renowned in heavy machinery for its exceptional properties:

• High Toughness: Absorbs immense shock and impact forces during cutting without cracking or developing fatigue fractures.

• Ultra-High Strength: Provides the structural rigidity needed to transfer the full 130-ton cutting force directly to the blades without body flex or distortion.

• Superior Wear Resistance: Withstands constant abrasion from metal-on-metal contact, drastically extending the service life of the entire shear body and minimizing long-term maintenance costs.

3. Cutting Edge Technology: Imported Blade Material

The most critical contact point—the blades—utilizes specially imported alloy steel. This choice is pivotal for performance:

• Exceptional Hardness & Edge Retention: The blades maintain a sharp cutting edge longer than conventional materials, ensuring clean cuts and consistent performance over hundreds of operating hours.

• Resistance to Chipping and Deformation: When encountering hardened steel or impurities, these blades are less likely to chip or roll, reducing downtime for blade repair or replacement.

• Optimized Geometry: The blade design works in tandem with the jaw opening and force profile to initiate cracks and shear material efficiently, reducing required energy input.

4. Robust Linkage & Mounting System

Engineered for 20-28 ton carriers, the mounting bracket and linkage pins are oversized and heat-treated. This ensures a secure, slop-free connection to the excavator, translating the machine's hydraulic power directly into cutting action without energy loss through mechanical play.

Primary Applications & Industry Use Cases

The GCE-28 Hydraulic Eagle Shear is a versatile tool designed for heavy-duty demolition, decommissioning, and scrap processing.

1. Structural Steel Demolition

• Building & Bridge Dismantling: Efficiently cuts through primary support elements like H-beams, I-beams, and wide-flange beams used in commercial structures and bridges. Its deep jaw and high force allow for quick segmentation of large frameworks.

• Industrial Plant Decommissioning: Ideal for dismantling factory support beams, conveyor structures, and processing plant frameworks, where speed and controlled cutting are essential for safety.

2. Scrap Metal Processing & Recycling Yards

• Vehicle Processing: Excellently suited for dismantling heavy-duty vehicles such as trucks, buses, rail cars, and agricultural equipment. It cleanly cuts through automotive beams, chassis frames, and axles, preparing material for the shredder or as dense, high-value scrap.

• Appliance & White Goods Processing: Can handle compressed piles of mixed scrap, cutting through tangled metal to reduce volume and sort materials.

3. Emergency & Disaster Response

• In scenarios like industrial accidents or structural collapses, the GCE-28's power and precision allow rescue and recovery teams to quickly and safely cut through wrecked steel structures to clear debris or create access points.

Unmatched Product Features & Competitive Advantages

1. Unrivaled Cutting Power and Efficiency:
The triple-stage cutting force (80/100/130 tons) allows operators to match power to the material. This "smart power" application results in faster cycle times, lower fuel consumption for the carrier, and less wear on the attachment.

2. Exceptional Durability and Lower Total Cost of Ownership (TCO):
The combination of the TDNM450 body and imported blades creates a synergistic effect on longevity. Users benefit from:

• Reduced frequency of blade changes.

• Minimal structural repairs over the attachment's lifespan.

• Higher uptime and availability.

3. Enhanced Operator Safety and Control:

• The stable, high-torque rotation allows for precise placement, keeping the operator at a safe distance from the cutting point.

• The controlled cutting action minimizes sudden material shattering or unpredictable fly-offs.

• Remote operation from the excavator cab ensures the operator is protected within the ROPS/FOPS structure.

4. Flexibility and Adaptability:

• Suitable for a broad range of 20-28 ton excavator 

• Effective on a wide array of materials beyond steel, including mixed metals in demolition sites.

5. Optimized for Material Handling and Logistics:

• The 460mm opening and 530mm depth allow it to act as a grapple and shear simultaneously. Operators can pick up, position, and cut material without changing attachments, significantly streamlining workflow.
