35Hz is the optimal frequency for ballast compaction: it breaks up tightly packed ballast particles without causing excessive vibration to rails or sleepers. This results in a denser, more load-resistant ballast bed that can withstand heavy train traffic (up to 25t axle loads) without settlement.
Single-sleeper mode is ideal for narrow sleeper spacings (e.g., subway tracks with 600mm spacing), while double-sleeper mode speeds up operations on mainlines (700mm+ spacing). Switching between modes takes less than 2 minutes via the control panel—no mechanical adjustments needed.
The tamping picks extend 50–100mm below the sleeper bottom, ensuring full compaction of the "critical zone" under sleepers (where false ballast often occurs). It also integrates track lifting and shifting functions: while tamping, it real-time corrects level (±2mm lateral error, ≤3mm longitudinal error) and direction—reducing secondary ballast disturbance and eliminating the need for separate alignment equipment.
A built-in safety protection system shuts down operations if the device deviates from preset parameters (e.g., excessive pressure). Its theoretical operating speed (0–2km/h adjustable) cuts track possession time by 30% compared to standard tamping devices—critical for minimizing disruptions to train schedules.

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 DC-32 Tamping Device is the core operating component of DC-32 Tamping Vehicles—a high-performance solution engineered for large-scale railway maintenance. Unlike basic tamping devices, it supports flexible switching between single-sleeper and double-sleeper tamping modes, adapting to varying sleeper spacings (e.g., 600mm, 700mm) across mainline, subway, and mining railways. Its design combines hydraulic drive, automated control, and safety protection systems to deliver 35Hz high-frequency vibration—rapidly disrupting compacted ballast, enabling tight particle interlocking, and boosting track bed density by 20%. Key advantages include deep sleeper penetration (avoiding false ballast and settlement), real-time track geometry correction, and fast operation (reducing track possession time). With a standard quantity of 1 unit, it is the backbone of efficient, precision-focused tamping projects.
| Theoretical operating speed | 0-2km/h adjustable |
| Longitudinal horizontal error | ≤3mm |
| Lateral horizontal error | ±2mm |
| Operating temperature range | -10℃~+40℃ |
| Applicable track gauge | Supports customized adaptation. We can provide customized product services 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 track construction: Tamping ballast beds for newly laid rails (mainline, subway, mining) to meet operational standards.
• Periodic mainline maintenance: Enhancing ballast density on busy lines (e.g., intercity railways) during quarterly or semi-annual shutdowns.
• Defect repair: Fixing localized issues (e.g., ballast loosening from track repairs) on high-priority lines (e.g., freight railways with daily cargo traffic).
• Overhaul projects: Supporting large-scale track overhauls (e.g., rail replacement) by recompacting ballast around new components and correcting alignment.
