The XG-type electric suspension track-crossing crane is a specialized lifting device designed to support the coal pulverizing systems of power plants, typically serving generator units. Its primary purpose is to facilitate maintenance of coal mills. The crane operates at a working duty class of A1 to A3 and is suitable for ambient temperatures ranging from -20°C to +40°C.
It is not suitable for lifting molten metals or handling toxic, flammable, or explosive materials. This product is a modular system, consisting of an electric hoist trolley, an electric double-girder suspension crane (main trolley), a (manual or electric) single/double-girder suspension crane (auxiliary trolley), and a track-crossing mechanism. The electrical system is operated and controlled via push-button switches.
The XG-type electric suspension track-crossing crane is a specialized lifting device designed specifically for coal pulverizing systems in power plants. It is mainly used for maintenance and servicing of coal mills and associated equipment. Typically installed in boiler rooms or coal mill workshops, it is ideal for light-load applications where operational stability and safety are critical, despite lower usage frequency.
The crane system is modularly composed of an electric hoist trolley, an electric double-girder suspension crane (main trolley), an auxiliary crane, and a track-crossing unit, allowing for adaptable installation.
The well-designed trolley system enables smooth transitions across different tracks, improving maintenance efficiency.
Operated via push-button controls and equipped with limit switches and overload protection to ensure safe operation.
Key components are standardized, enabling quick servicing and reduced maintenance costs.
