Description
Rail Grinder Overview
The CM-4.7II is a new generation of eco-friendly intelligent grinding equipment, innovatively upgraded from the proven NCM-5 II multifunctional vertical axis turnout grinder platform.
The machine fully retains the core advantage of versatility from its predecessor. It is capable of efficiently performing precision maintenance in turnout areas, as well as grinding operations on the rail head surface, repair welds, and joint welds of ordinary tracks. It features high operation efficiency, simple operation, fast on/off-track transition, and strong adaptability.
The core of this upgrade is the innovative power system combining a DC brushless motor with a high-capacity lithium battery. This completely eliminates issues associated with traditional motors or internal combustion engines, such as vibration, noise, and exhaust emissions. It creates a quieter, cleaner, and healthier working environment, significantly improving operator comfort and job site efficiency. It is an ideal solution for urban rail transit, enclosed depots, and areas with stringent environmental requirements.
Key Features
⚪ Powered by lithium battery and driven by a DC brushless motor, enabling zero emissions, low vibration, and low noise operation, improving the work environment.
⚪ Designed specifically for turnouts, while also perfectly suitable for various tasks on ordinary rails, such as rail head profiling and weld grinding.
⚪ Vertical axis design with grinding wheel offering extensive vertical, lateral travel, and angular deflection, adapting to complex profiles; fast on/off-track transition.
⚪ Integrated intelligent control unit enables precise feed control, enhancing consistency and quality of grinding operations.
