1. 35Hz high-frequency vibration rapidly disrupts the compacted structure of ballast particles, facilitating their re-interlocking into a tight configuration. This significantly enhances the density, load-bearing capacity, and resistance to deformation of the ballast bed. 2. The tamping pick is inserted below the bottom surface of the sleeper to fully compact the ballast under the sleeper, effectively avoiding the problem of track settlement caused by shallow false ballast. |
3. Combined with the function of track lifting and track shifting, while tamping and compacting the ballast, the track's geometric parameters such as level, height, and direction are corrected in real time to reduce secondary disturbances to the ballast.
4. Highly efficient operations, making it suitable for large-scale line maintenance and significantly reducing track possession window operation time.
The DCL-32’s unique hybrid design allows it to operate at a continuous uniform speed for straight track sections, maximizing efficiency, while switching to step-by-step movement for curved or irregular track segments—ensuring precise ballast compaction. This flexibility makes it suitable for both simple and complex track layouts.
Equipped with 35Hz high-frequency vibration technology, the DCL-32 rapidly breaks down compacted ballast particles, allowing them to re-interlock into a dense, stable structure. This process enhances the ballast bed’s load-bearing capacity by up to 25% and reduces long-term deformation, extending the interval between maintenance cycles.
Integrated with track lifting and shifting functions, the DCL-32 corrects track level, height, and direction in real time during tamping. This synchronization minimizes secondary disturbances to the ballast bed, ensuring that the track remains aligned and ready for train operations immediately after maintenance.
The DCL-32 operates reliably in temperatures ranging from -10℃ to +40℃, making it suitable for use in diverse climates—from cold northern regions to warm southern areas. Its components are designed to withstand temperature fluctuations without compromising performance.

The DCL-32 Tamping Device is the core component of the DCL-32 continuous-operation tamping vehicle, engineered for large-scale railway maintenance projects that demand high efficiency and consistency. It features an innovative design that combines continuous uniform-speed operation with step-by-step movement of the working trolley—striking a balance between speed and precision. By integrating a hydraulic drive system, automatic control system, and safety protection devices, the DCL-32 delivers efficient vibratory compaction of ballast under sleepers on both sides of the rail. Unlike smaller tamping devices, it is optimized for long-distance track sections (e.g., intercity railways, freight lines) where minimizing track possession time is critical.
| Theoretical operating speed | 0-2km/h adjustable |
| Longitudinal horizontal error | ≤3mm |
| Lateral horizontal error | ±2mm |
| Operating temperature range | -10℃~+40℃ |
| Applicable Track Gauge | Customized adaptation is supported. Customized product services can be provided according to your needs. |

Specific usage scenarios:
Tamping operation of new railway track bed.
Specific usage scenarios:
Improve the ballast density during periodic maintenance, defect repair and overhaul of existing lines.
• New Railway Construction: Compacting ballast for long-distance new rail lines (e.g., high-speed railways, freight corridors) to establish a stable foundation.
• Existing Line Overhauls: Enhancing ballast density during large-scale overhauls of aging tracks, where extensive sections need to be serviced quickly.
• Periodic Maintenance of High-Traffic Lines: Ideal for busy railways (e.g., commuter lines, freight routes) where track possession windows are short, as it covers more ground in less time.
• Complex Track Sections: Adapts to curved tracks, uneven sleeper spacing, and high-load sections (e.g., near bridges or tunnels) with consistent performance.
