Unpacking the Core Technology: The Silent Box Advantage

What sets the GCB75 apart is its advanced Silent Box Design. Unlike traditional open-side breakers, this model features an enclosed, reinforced housing that contains and dampens the sound generated during operation. This innovative engineering achieves a significantly lower noise level of just 115 dB, enhancing operator comfort and compliance with environmental standards without compromising an ounce of power.

Key Features & Technical Superiority

The GCB75 is engineered for peak performance and longevity. Here’s a closer look at its defining features:

· •High Impact Energy (1017 Joules):​ Delivers a powerful blow to tackle the toughest materials, ensuring faster breaking cycles and improved productivity.

· •Optimized Frequency (400-800 BPM):​ The automatic variable frequency technology allows the breaker to adjust its impact rate based on material hardness, maximizing efficiency and protecting the carrier from harmful vibrations.

· •Robust Construction & Auto-Greasing:​ Built with high-strength, wear-resistant steel, the GCB75 is designed for a long service life. The integrated automatic greasing system ensures continuous lubrication of the tool bushing, reducing wear and maintenance needs.

· •Precision Hydraulic Control:​ With an operating pressure of 120-150 Bar​ and a required oil flow of 50-90 l/min, it ensures optimal compatibility with your 6-9 ton excavator, delivering maximum power transfer and fuel efficiency.

· •Standard 75mm Tool Diameter:​ The perfect balance between focused impact force and tool durability for a wide range of medium-duty applications.
