It can move and operate on rails, and can switch between road and rail travel modes.

Railway excavators usually refer to dual-purpose excavators for both road and rail use. Their core feature is that they are equipped with both tracks/tires and rail wheels, allowing them to switch between road and rail travel.

The dual-purpose road-rail excavator is a special type of engineering machinery specifically designed for railway construction and maintenance. It is not simply an ordinary excavator placed on the tracks, but rather a systematic and safety-oriented redesign specifically for railway working conditions.

The dual-purpose road and rail excavator has both tracked and steel wheel/guide rail wheel walking systems.

Main Application Scenarios

The core value of this type of equipment lies in replacing manual labor and significantly improving efficiency during "maintenance windows" (construction time between train runs):

Railway Overhaul: Mechanized replacement of sleepers, ballast removal/cleaning, track bed tamping, and slope repair.

Emergency Repair: Rapid cleanup and track restoration after track collapses and accidents.

Auxiliary Construction: Excavation of cable trenches along railway lines, and material loading and unloading (e.g., unloading while riding on train carriages, significantly improving efficiency compared to manual labor).

The core advantages of the sleeper changing machine are very clear: it replaces manual labor with machinery, completely changing the traditional railway sleeper changing operation's "slow, dangerous, and tiring" nature.

1. Extremely high efficiency, significantly reducing operation time – this is the most direct advantage of the sleeper changing machine.

2. Significantly improved safety, reducing the risks associated with manual operation.

3. Multifunctionality and strong adaptability, reducing equipment costs.

4. Flexible relocation, with minimal disruption to transportation.

5. Optimized operation quality and environmental friendliness.
