Core Technology and Engineering Principles

Advanced Hydraulic System Integration

The GCH-38 operates at an industry-leading 380 Bar rated pressure, ensuring maximum force transmission with minimal energy loss. Our proprietary hydraulic flow optimization technology synchronizes with your excavator’s system, reducing cycle times by approximately 15-20% compared to conventional models. The precisely calibrated hydraulic cylinders convert hydraulic power into 225 tons of crushing force with exceptional efficiency.

Reinforced Structural Design

Constructed from high-grade Swedish steel with specialized heat treatment, the GCH-38 features a reinforced box-style body that distributes stress evenly across the structure. The strategic placement of wear-resistant plates at critical contact points extends service life by 40% over standard designs, while the optimized geometry ensures consistent force application throughout the jaw movement range.

Intelligent Jaw Geometry

The 950mm opening width represents the optimal balance between material capture capacity and force concentration. Our parabolic jaw design creates a progressive crushing action that initially grips material securely before applying maximum force at the optimal angle, reducing rebound and improving material fragmentation consistency.

Primary Applications and Use Cases

Reinforced Concrete Separation

The GCH-38 excels in separating rebar from concrete—a critical process in construction demolition and recycling operations. The combination of high tip force and precise jaw control allows operators to cleanly shear reinforced concrete while minimizing damage to valuable rebar for recycling. This capability significantly increases scrap value recovery while reducing downstream processing costs.

Building Demolition and Deconstruction

For controlled demolition projects requiring precision, the GCH-38 provides the accuracy needed for selective dismantling. The tool's balanced design allows for excellent visibility and control when working on structural elements, while its power handles thick concrete sections efficiently.

Material Processing and Size Reduction

Beyond demolition, the GCH-38 serves as an efficient primary crusher for processing concrete rubble on-site. The consistent output size reduces the need for secondary processing in many applications, allowing direct feeding of screening plants or preparation for recycling facilities.

Bridge and Infrastructure Demolition

The tool's high reach capability combined with its substantial crushing force makes it ideal for infrastructure projects where access may be challenging and materials are particularly robust.

Competitive Advantages and Differentiating Features

Unmatched Power-to-Weight Ratio

At 1800kg, the GCH-38 delivers one of the industry's best power-to-weight ratios for its class. This optimized weight distribution ensures minimal impact on excavator stability while maximizing available force at the jaws, translating to lower fuel consumption per ton of material processed.

Enhanced Durability and Reduced Maintenance

Our quadrant-style rotation system with oversized pins and bushings increases wear surface area by 30% compared to conventional designs. The sealed lubrication points and protected hydraulic lines significantly reduce maintenance requirements while extending service intervals.

Operator-Focused Design

The GCH-38 features an optimized center of gravity that minimizes excavator counterweight requirements while maintaining excellent visibility to the working area. Reduced vibration transmission to the carrier machine decreases operator fatigue during extended operation.

Versatility Across Applications

With quick-change compatibility with most 30-38 ton excavators and multiple jaw configurations available, the GCH-38 adapts to various material types and job requirements without sacrificing performance in its primary applications.

Performance Analysis and Operational Economics

Efficiency Metrics

Field tests demonstrate that the GCH-38 processes reinforced concrete approximately 25-30% faster than comparable models in its class. The reduced cycle time combined with lower maintenance requirements typically delivers a return on investment within 6-8 months for active demolition contractors.

Cost Reduction Factors

• Fuel Efficiency: Optimized hydraulic flow reduces carrier machine fuel consumption by an estimated 12-15%

• Downtime Reduction: Enhanced durability components increase mean time between failures by approximately 40%

• Recycling Revenue: Cleaner separation of materials increases scrap value recovery by up to 20%

• Transportation Savings: On-site material reduction decreases hauling requirements by 30-50%
