Innovative Design: The Banana-Type Advantage

Ergonomic Engineering for Modern Applications

The R75's distinctive "banana" curved housing isn't merely aesthetic – it represents a fundamental rethinking of breaker ergonomics and performance. Unlike traditional straight-body breakers that create a straight force vector, the curved design offers several critical advantages:

1. Enhanced Visibility: Operators enjoy significantly improved sightlines to the working tool and impact area, crucial for precision tasks like slab edge work or wall demolition.

2. Optimized Weight Distribution: The curved housing shifts the center of gravity closer to the excavator arm, reducing stress on mounting components and improving overall machine stability.

3. Reduced Rebound Effect: The angled impact mechanism directs more energy into the material being broken rather than back through the excavator, decreasing operator fatigue and equipment wear.

4. Space Optimization: The compact front profile allows operation in exceptionally tight quarters where traditional breakers would be impossible to position correctly.

Core Technology: Pure Hydraulic System with Auto-Frequency Modulation

Revolutionary Impact Control System

As a pioneer in auto-frequency modulation technology, Guchuan has equipped the R75 with our proprietary intelligent impact system that represents a generational leap in breaker performance:

Adaptive Frequency Technology: Unlike conventional fixed-frequency breakers, the R75 continuously monitors working conditions through multiple pressure and temperature sensors. The system automatically adjusts impact frequency (520-1000 BPM) based on material hardness, from fragile concrete to medium-hard rock. This intelligent adaptation delivers maximum efficiency regardless of application, preventing energy waste on soft materials while ensuring sufficient power for hard substrates.

Energy Recovery System: Our patented hydraulic circuit captures and reuses energy from the return stroke, significantly reducing overall hydraulic demand by up to 18% compared to conventional designs. This not only lowers fuel consumption but also reduces heat generation – a primary cause of component failure in hydraulic systems.

Precision Accumulator Design: The 40-bar accumulator system serves as an energy buffer and shock absorber, smoothing power delivery and protecting both the breaker and carrier from damaging shock loads. Our nitrogen-charged diaphragm accumulator maintains consistent performance across extreme temperature variations from -20°C to 60°C.
